4 Gladman Developments Ltd Wilburton Road, Haddenham NON-TECHNICAL SUMMARY The Site The study site lies south-west of Ely, to the south of Wilburton Road and is approximately 4.12 hectares in area. It has a significant fall to the south of around 5m from Wilburton Road South. Currently the site is Greenfield, naturally draining agricultural land. It is intended to construct up to 100 houses and associated infrastructure on around 3.14 hectares of the site. Flood Risk The study area is located within the Environment Agency s Flood Zone 1 - lowest risk of flooding and, as such, the residential development is considered appropriate and no sequential test is necessary. The EA and East Cambridgeshire District Council have no record of historical flooding for the study area. Pedestrian and vehicular safe access to and from the development will be achievable under all conditions via the proposed access road off Wilburton Road and a formal evacuation plan is not therefore required. Ground floor levels for the properties should nevertheless be set above proposed surrounding levels across the development to provide a nominal freeboard to allow overland flow under exceptional conditions. Drainage The ground conditions may rule out infiltration techniques for surface water disposal but further site investigation would be required to determine local permeability. Anglian Water has confirmed that surface water flows can be accepted into their surface water sewer at a rate not exceeding 20l/s and this should be confirmed as acceptable to the EA following detailed design as the outfall discharges directly to a watercourse. The outline drainage strategy presents attenuation and storage of surface water in underground storage systems and balancing ponds as the most appropriate surface water drainage solution for the development. Foul sewage may be discharged into the existing public foul sewers that cross the site subject to confirmation with Anglian Water following detailed design. LK Consult January 2014 Ref: FRA Final

5 Gladman Developments Ltd Wilburton Road, Haddenham 1. INTRODUCTION 1.1 Brief LK Consult Ltd (LKC) has been commissioned by Gladman Developments Ltd to undertake a Flood Risk Assessment and outline drainage strategy in support of the Outline Planning Application for a proposed residential development off Wilburton Road, Haddenham. 1.2 Planning Policy Context Government policy with respect to development in flood risk areas is contained within the Department of Communities and Local Government The National Planning Policy Framework 3 (DCLG, 2012) and accompanying Technical Guidance of March 2012 (DCLG 2012) which supersedes Planning Policy Statement 25 (PPS25) Development and Flood Risk which was issued in December 2006 and revised in April However, guidance for the NPPF is brief and the principles and requirements of PPS25 remain largely unchanged. PPS25 practice guides on flood risk and coastal change remain in place until Government chooses to replace them. LK Consult January 2014 Ref: FRA Final 1

The study area is located at National Grid Reference E, N and is approximately 4.12 ha in area. 2.2 Study Area Description and A walkover visit was undertaken in Appendix E. Surroundings on 25th June 2013 and key photographs are providedd The study area is 100% Greenfield, naturally draining and is currently used for agricultural land, currently the field is planted with wheat. The study area slopes to the South. The northern section of thee study area is significantly elevated when compared to the southern boundary. Access too the study area is gained via a break in the hedgerow of Wilburton Road (see photo 1) and dense hedgerows surrounded the northernn boundary, with all other boundaries open. 2.3 Topography No topographic survey has been supplied but the site has a significant fall from Wilburton Road South. The fall is estimate at around 5m. 2.4 Ground Conditions The geological map for the location (see screenshot) shows the study area has bedrock geology of the West Walton formation, clays to the south and the Greensand Group to the north consisting of Mudstone, Siltstone and Sandstone. Screenshot of geological solid and drift map. m In order to ascertain shallow ground conditions, LKC undertook thee hand excavation of 3 trial auger holes to the study areaa as part of the walkover visit. The trial holes generally found ground conditions across the site to be a slightly sandy clay, with frequent fine rounded gravel. LK Consult Ref: FRA Final 2 January 2014

7 Gladman Developments Ltd Wilburton Road, Haddenham Such ground conditions are likely to constrain the use of infiltration based SuDS techniques across the study area but further study would be able to confirm this. Further details of the study area s geology are presented in LKC s Preliminary Risk Assessment report of July 2013 (document ref. CL-602-LKC ) Water and Drainage Environment Public Sewerage Foul and Surface Water drainage is present within the plot. There is a 150mm dia. foul sewer running across the northern area to the south of number 18 Wilburton Road. Along the western boundary there is a 300mm dia. surface water sewer running parallel to a 150mm dia. Foul sewer these enter the plot slightly to the east of the western boundary Private Drainage Based on available information, there is no known private drainage within the boundary of the study area. There will be some private drainage adjacent to 18 Wilburton Road this is likely to connect to the public drainage network. Any land drainage located during construction should be either removed if proven to be redundant or diverted to suit the location of new residential dwellings Watercourses There are no watercourses within the development but there is an outfall for the public surface water sewer 200m to the south of the plot boundary Groundwater Information on the Environment Agency website shows the study area is not in a groundwater protection zone area, however the Northern edge of the site indicates that the bedrock is classed as a principal aquifer.

INFORMATION GATHERED This section contains the responses received to enquiries submitted to obtain information relevant to preparing this Flood Risk Assessment. These responses are summarised below with complete copies contained within Appendices B and C. A summary of other relevant information obtained from documentary sources is also included in this section. 3.1 Environment Agency The responses received from the Environment Agency are summarised below: The study area is located within Flood Zone 1. There are no records of flooding are available. 3.2 Anglian Water A commercial water enquiry and a pre-planning assessment report have been received from Anglian Water. These show both foul and surface water public sewers crossing the site. 3.3 East Cambridgeshire District Council (ECDC) ECDC confirmed no flooding has been recorded on the site but flooding has been recorded at the treatment works 300m south of the development, they have contacted Anglian Water for details but so far have not received any response. 3.4 Strategic Flood Risk Assessment The Strategic Flood Risk Assessment 5 for ECDC was prepared to help identify those areas in the County most at risk of flooding and to provide the basis from which to apply the NPPF to planning applications. The SFRA indicates that the study area is not within a postcode area that has suffered from flooding from any source up to This corresponds with the EA and Council responses. LK Consult January 2014 Ref: FRA Final 4

DEVELOPMENT PROPOSALS On the study area it is proposed to construct up to a hundred residential units with associated roadways, parking, gardens and landscaped areas. Access will be from Wilburton Road at the northern boundary of the study area. 4.1 Sequential Test The NPPF 3 requires that the Sequential Test be applied to development proposals in Flood Zones 2 and 3 to determine if there are any reasonably available and suitable alternative sites at lower flood risk. Since the study area is located in Flood Zone 1, a sequential test should not be required for planning as the more vulnerable residential end-use is appropriate in Flood Zone 1. As the area of the study area is greater than one hectare, the FRA should address the vulnerability to flooding from all possible sources and also consider the impact of the development on surface water runoff accounting for climate change and the potential to increase flood risk elsewhere. The outline drainage strategy in section 6 provides an overview of the SuDS techniques which may be applicable to the study area. The issues of actual flood risk are discussed in section Exception Test Although an exception test is not required for planning, the issues of safety and reduction in flood risk to others required by an Exception Test are addressed in this document. LK Consult January 2014 Ref: FRA Final 5

10 Gladman Developments Ltd Wilburton Road, Haddenham 5. ASSESSMENT OF FLOOD RISK 5.1 Sources of flooding The risk of flooding from the following flood sources has been considered: Fluvial The Environment Agency has confirmed the study area is within Flood Zone 1. Therefore the flood risk associated with this source is considered negligible. Tidal The study area is remote from the sea and tidally influenced water bodies; therefore, the flood risk associated with this source is considered negligible. Pluvial (Rainfall) The only impermeable area at a level generally above that of the study area is Wilburton Road and this is served by a positive drainage system by means of gullies within the carriageway. It is therefore unlikely that this source will affect the site. Groundwater The ECC Strategic Flood Risk Assessment 5 refers to there being limited aquifers in at the Northern edge of the site but the EA website refers to a principal aquifer in this location. Due to the nature of the soils the amount of groundwater emergence will be limited. Sewers Anglian Water sewerage records indicate the presence of a number of sewers crossing the study area. No reference has been made in the predevelopment enquiry to any known sewerage flooding problems in the area and they have indicated that they have some spare capacity. Therefore, the flood risk associated with this source is considered negligible. Artificial sources There are a number of water pipes running along Wilburton Road the road generally falls towards the east for all but a catastrophic failure of the largest 10inch main the water would be contained within the road. There is also a water tower on the opposite side of the road behind number 19 Wilburton Road, the ground generally falls to the south and the east a catastrophic failure of the tower could potentially allow water to cross the road and enter the site but the volume would be limited and the tower would be regularly inspected and drawn down if any problems were encountered. There is an artificial source located close to the study site in the form of a pond at approximately 200m south of the site and at a lower ground level. The flood risk associated with artificial sources is therefore considered negligible due to the topography and the water company s maintenance regime. LK Consult January 2014 Ref: FRA Final 6

11 Gladman Developments Ltd Wilburton Road, Haddenham 6. FLOOD MITIGATION MEASURES 6.1 Safe Access Safe and dry access is available onto Wilburton Road via the Northern Boundary of the study area (located on Flood Zone 1). In this situation, a formal emergency evacuation plan will not be necessary and no mitigation is proposed. 6.2 Flood Resistance and Resilience The development proposed may be subject to flooding at more extreme events than those considered. However the risk appears to be sufficiently low that flood resilience measures need not be included in ground floor construction of the properties. 6.3 Groundwater Flooding Groundwater flooding is not considered to be a risk to the development 6.4 Residual Risks It is impossible to completely guard against flooding since extreme events greater than the 1:1000 year event are possible. However, the study area s location in Flood Zone 1 and the elevated position of the development will safeguard it from localised fluvial flooding during extreme rainfall events and fluvial flooding events outside the scope of this assessment. Ground floor levels of the properties should be set nominally above proposed surrounding levels across the development in order to provide a freeboard to allow overland flow away from the properties under exceptional conditions.

12 Gladman Developments Ltd Wilburton Road, Haddenham 7. OUTLINE DRAINAGE STRATEGY 7.1 Existing Drainage The study area has existing drainage pipes crossing the site but there are no other features to convey surface water runoff towards sewers or a watercourse. 7.2 Proposed Foul Drainage Anglian Water has confirmed that it is acceptable to connect the foul flows from the site into their existing drainage system. There are two locations for the foul flows to be connected from the development by gravity fed systems. The first location is the 150mm dia. pipe between manholes 9002 and 7002 that crosses the plot to the north of the development where 20 properties could be connected. The second is to connect to manhole 6802 where the remainder of the 100 properties could connect. This foul sewer enters the plot behind number 27 Orchard Way before heading towards the western boundary where it turns southwards and continues within the western boundary of the plot. The development is within the catchment of the Haddenham Water Recycling Centre which has the capacity to treat the flows from the development. The guidance in Sewers for Adoption 7th Edition 5 would require sewers to be designed for a capacity based on 4000 litres per dwelling per day. In this case therefore, 100 houses would give an instantaneous flow rate of 4.63 l/s from the study area. This is considerably greater than the water consumption expected, which would be based conservatively on 180 litres per head per day at an average occupancy of 4 people per house (also conservative). This would equate to 720 litres per dwelling per day and a total predicted flow of 72.0m3 per day for the development. 7.3 Proposed Surface Water Drainage Requirements for surface water drainage at the study area. PPS25 recognises that flood risk and other environmental damage can be managed by minimising changes in the volume and rate of surface run-off from development sites through the use of Sustainable Drainage Systems (SuDS), this being complementary to the control of development within the floodplain. SuDS will not alleviate flooding in an area prone to flooding; however, properly designed SuDS have the potential to prevent the surface water runoff from new development worsening the flood risk. PPS25 Annex F paragraph F5 states that The effective disposal of surface water from development is a material planning consideration in determining proposals for the development and use of land. PPS25 Annex F paragraph F6 states that Surface water arising from a developed area should, as far as practicable, be managed in a sustainable manner to mimic the surface water flows arising from the site prior to the proposed development, while reducing the flood risk to the site itself and elsewhere, taking climate change into account. This should be demonstrated as part of the flood risk assessment. The Building Regulations Requirement H3 stipulates that rainwater from roofs and paved areas is carried away from the surface to discharge to one of the following, listed in order of priority: LK Consult January 2014 Ref: FRA Final 8

13 Gladman Developments Ltd Wilburton Road, Haddenham a) an adequate soakaway or other adequate infiltration system, b) a watercourse or, where that is not practicable, c) a sewer SuDS selection The aim of the SUDS scheme is to ensure that the proposed drainage from the development does not cause or add to any existing flooding issues in the area. It is essential that such schemes do not compromise the new properties. The topography of the study area should be taken into account in order to maximise the benefits of potential storage at low-points. The detailed design of the drainage scheme should follow on from consideration of the planning application. The detailed designs must ensure below ground storage of the runoff for the critical rainfall event (typically the 1:30 year storm) whilst incorporating failsafe devices/features for rainfall events falling outside of this category, i.e. the 1:100 year storm + 30% allowance for climate change. The sandy clay nature of the site (see sections 2.4 and 2.5.4) indicate that the use of infiltration SuDS may not be feasible for the development, but further ground investigation would be needed to confirm if it is achievable. As such, the outline drainage strategy considers the use of attenuation and storage based SuDS to be the most appropriate technique at this time. There are no watercourses within the vicinity of the study area boundary in which to discharge surface water, so an outfall to the public surface water drainage system will be required. In terms of the potential pollution risk to controlled waters, the residential development should incorporate two treatment stages for roads and parking areas as part of the SuDS management train (in accordance with CIRIA guidance 6 ). Roof waters can generally be discharged without treatment. It is anticipated that the surface water drainage system will be offered for adoption by Anglian Water. The table below provides a summary of the SuDS options appraisal for the development: SuDS Option Appropriate Comments to Development Soakaways * Due to the nature of the ground conditions, the use of infiltration systems is unlikely to be feasible at the development. Infiltration basin * Depressions that store and dispose of water via infiltration. Unlikely to be appropriate given the ground conditions. Sand filter * Treatment devices using sand beds as filter media. Filter strip Engineered filters that use vegetation to remove and treat runoff. The filter strip is sloped to allow sheet flow across the vegetated strip. A filter strip offers no storage and is used solely to remove pollutants from surface water. Filter drains * Linear trenches filled with a permeable granular material, often with a perforated pipe in the base of the trench. Detention basin * Dry depressions designed to hold water for a specific retention time. Swales X Swales are shallow grass-lined channels that provide capacity for conveying flows at a controlled rate into ponds and watercourses. The use of swales is not considered appropriate to the study area due to the relatively steep site gradients. LK Consult January 2014 Ref: FRA Final 9

14 Gladman Developments Ltd Wilburton Road, Haddenham Rain water harvesting * Rainwater harvesting collects the rain which falls onto roofs, then stores it in a tank until required for a non-potable use. When required, the water is pumped to the point of use, thus displacing what would otherwise be a demand for mains-water. In the process, a volume of water is kept out of the storm-water management system, thereby helping to reduce flooding risks. Rainwater harvesting systems are currently not included in the development proposals. Green roofs * Green roof installations can help to reduce surface water runoff from roof areas depending on the system specified. Green roofs are not currently included in the development proposals. Geo-cellular storage systems Permeable Pavements - constructed in conjunction with granular and geo-cellular storage systems Modular block systems can be used to provide an underground storage facility. Any geo-cellular storage systems should be tanked with a geo-membrane to provide attenuation storage rather than infiltration at the development. Permeable pavements allow inflow of rainwater into underlying construction. Areas of permeable macadam/paving have been considered to accommodate climate change flows, connecting to geo-cellular storage before out falling to the private drainage network (given that ground conditions are not considered suitable for infiltration systems). Any geo-cellular storage systems would have to be lined with an impermeable membrane to provide storage rather than infiltration. Ponds Attenuation ponds will be used to offset the increase in surface water flows attributable to climate change and increased area of hardstanding, in order to minimise the risk of flooding to and from the proposed development. Ponds will attenuate the surface water flow prior to a pumped discharge to the public surface water sewers. The storage volume afforded by these features should not include any permanent water in the pond. Oversized Pipes * Oversizing the pipes that make up the on-site drainage network is a cost effective method for providing attenuation storage within the network. Such systems could be considered on the parts of the development where gradients are relatively flat; however the shallow bedrock on the study area is likely to constrain the use of oversized pipes. Tanks * Prefabricated underground tanks could be considered at the in order to provide storage to attenuate surface water runoff. The shallow bedrock on the study area is however likely to constrain the use of tanks. Flow control devices Key: Suitable for use given the nature and scale of the development The peak flow rates will be controlled by flow control devices e.g. hydrobrakes, pump stations and restricted orifices. Flow control devices enable the discharge to be restricted to a constant rate from the development. Discharge rates are to be in line with the Greenfield runoff rate for the study area or as instructed by Anglian Water. * Possibly suitable for use not included in the client and architect design proposal at present X Not suitable Figure 1 LK Consult January 2014 Ref: FRA Final 10

15 Gladman Developments Ltd Wilburton Road, Haddenham Surface Water Storage Requirements Surface water storage and Greenfield Runoff calculations based on the HR Wallingford procedure (IH 124 Greenfield runoff method) have been undertaken for the 4.12 Ha development and the output report is presented in Appendix D. Assuming a total area of, an area of significant public open space comprising 0.96Ha and a development impermeable area of 0.96Ha, the Wallingford report provides the following key information for the development: 1 in 1 year Greenfield runoff rate: l/s 1 in 30 year Greenfield runoff rate: 46.77/s 1 in 100 year Greenfield runoff rate: l/s Attenuation storage volume: m 3 (1 in 30 year storage) Long term storage volume: 0 m 3 (1 in 100 year + climate change storage less the 1 in 30 year) Attenuation storage aims to limit the peak rate of runoff from the development to the receiving sewer to the corresponding Greenfield runoff for a range of annual flow rate probabilities. Long-term storage aims specifically to address the additional volume of runoff caused by the development. This is particularly critical for catchments that are susceptible to flooding downstream of the proposed development. The basis for sizing this storage is the 100 year 6 hour rainfall event. The calculations therefore show that the total required volume of attenuation storage with long term storage is m 3. The potential SuDS components that could provide this volume of storage for the development are indicated on Figure 1. These features comprise a series of tanks or geocellular (lined) systems and a balancing pond situated at areas of low elevation. Permeable paving should also be considered for use where possible on driveways and public parking areas. To ensure that no surface flooding occurs during a 1 in 30 year storm event, a series of tanks or geocellular (lined) systems with a total storage volume of m 3 are to be provided at the development. It is anticipated that surface water will flow at a controlled rate from the storage system into the existing surface water sewer. For storms events with a return period of greater than 1 in 30 years up to the 1 in 100 year (plus 30% for climate change), flows would be transferred from the tanks or geocellular systems and via overland flow routes into the balancing ponds (to be constructed with appropriate freeboard) so that flood water is temporarily retained on the development. Flow control devices such as hydrobrakes and/or restricted orifice plates would be required downstream of each of the storage features. The use of a surface water pumping station downstream may be necessary depending on relative levels of the surface water sewer and attenuation features. Anglian Water has stated that it is acceptable to discharge a flow of 20l/s into the surface water sewer at manhole This is more than the calculated 1 in 1 year Greenfield Runoff value in the calculations. There are a number of easement requirements stated within the report from Anglian Water that may have an effect upon the layout of the development depending upon the exact location of the existing drainage network.

17 Gladman Developments Ltd Wilburton Road, Haddenham 8. CONCLUSIONS AND RECOMENDATIONS The study area is shown on published mapping to be located within the Environment Agency s Flood Zone 1 - lowest risk of flooding. As such, the residential development is considered appropriate in terms of the sequential test. The EA and East Cambridgeshire District Council have no historical flooding records for the study area. Pedestrian and vehicular safe access to and from the development will be achievable under all conditions via the proposed access road off Wilburton Road. A formal evacuation plan is not required. Ground floor levels for the properties should be set above proposed surrounding levels across the development to provide a nominal freeboard to allow overland flow under exceptional conditions. The clay content encountered within the trial holes and the mudstone bedrock at the southern part of the study area may rule out SuDs infiltration techniques but further site investigation would be required to determine local permeability. The northern half is underlain by a principal aquifer so infiltration techniques may not be considered appropriate. Surface water flow from the development will need to be attenuated to a rate of 20l/s to discharge into the public SW sewer that crosses the site in the absence of a suitable watercourse within the vicinity of the study area; this has been confirmed as acceptable to Anglian Water, this should be confirmed as acceptable to the EA following detailed design as the outfall discharges directly to a watercourse. The outline drainage strategy presents attenuation and storage of surface water in underground storage systems and balancing ponds as the most appropriate surface water drainage solution for the development. Foul sewage may be discharged into the existing public foul sewers that cross the site. Flows from 20 properties for the most run parallel to Wilburton Road and the remaining 80 properties into the foul sewer running inside the western boundary subject to confirmation with Anglian Water following detailed design.

45 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 1 Answer Informative Where relevant, please include a copy of an extract from the public sewer map A copy of an extract of the public sewer map is included, showing the public sewers, disposal mains and lateral drains in the vicinity of the property. Public Sewers are defined as those for which the Sewerage Undertaker holds statutory responsibility under the Water Industry Act Anglian Water Services Limited is not generally responsible for rivers, watercourses, ponds, culverts or highway drains. If any of these are shown on the copy extract they are shown for information only. An extract from the public sewer map is enclosed. This will show known public sewers in the vicinity of the property and it should be possible to estimate the likely length and route of any private drains and/or sewers connecting the property to the public sewerage system. Assets other than public sewers may be shown on the copy extract for information. Question 2 Answer Informative Where relevant, please include a copy of an extract from the map of waterworks A copy of an extract of the map of waterworks is included, showing water mains, resource mains or discharge pipes in the vicinity of the property. The map of the waterworks has been supplied by: Anglian Water Services Limited PO Box 770 Lincoln LN5 7WX Tel: The 'water mains' in this context are those which are vested in and maintainable by the water company under statute. Assets other than public water mains may be shown on the plan, for information only. Water companies are not responsible for private supply pipes connecting the property to the public water main and do not hold details of these. These may pass through land outside of the control of the seller, or may be shared with adjacent properties. The buyer may wish to investigate whether separate rights or easements are needed for their inspection, repair or renewal, please refer to Question 23. The enclosed extract of the public water main record shows known public water mains in the vicinity of the property. It should be possible to estimate the likely length and route of any private water supply pipe connecting the property to the public water network. Question 3 Answer Informative Does foul water from the property drain to a public sewer? This enquiry appears to relate to a plot of land or a recently built property. It is recommended that drainage proposals are checked with the developer. Anglian Water Services Limited is not responsible for any private drains and sewers that connect the property to the public sewerage system, and does not hold details of these. The property owner will normally have sole responsibility for private drains serving the property. If foul water does not drain to the public sewerage system the property may have private facilities in the form of a cesspit, septic tank or other type of treatment plant. An extract from the public sewer map is enclosed. This will show known public sewers in the vicinity of the property and it should be possible to estimate the likely length and route of any private drains and/or sewers connecting the property to the public sewerage system. Question 4 Answer Informative Does surface water from the property drain to a public sewer? This enquiry appears to relate to a plot of land or a recently built property. It is recommended that drainage proposals are checked with the developer. Anglian Water Services Limited is not responsible for private drains and sewers that connect the property to the public sewerage system, and do not hold details of these. The property owner will normally have sole responsibility for private drains serving the property. If on inspection the buyer finds that the property is not connected for surface water drainage, the property may be eligible for a rebate of the surface water drainage charge. Details can be obtained from the company tel: If surface water does not drain to the public sewerage system the property may have private facilities in the form of a soakaway or private connection to a watercourse. Ref: Land off, Wilburton Road, Haddenham, ELY,

46 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 5 Answer Informative Is a surface water drainage charge payable? Records confirm that a surface water drainage charge is not payable for the property. Where surface water from a property does not drain to the public sewerage system no surface water drainage charges are payable. Where surface water charges are payable but upon inspection the property owners believe that surface water does not drain to the public sewerage system, application can be made to the water company to end surface water charges (freephone for more details). Question 6 Answer Informative Does the public sewer map indicate any public sewer, disposal main or lateral drain within the boundaries of the property? The public sewer map included indicates that there is a public sewer, disposal main or lateral drain within the boundaries of the property. On 1 October 2011, private sewers that serve a single property and lie outside the boundary of that property, were transferred into public ownership. Therefore there may be additional public sewers, disposal mains or lateral drains which are not recorded on the public sewer map but which may prevent or restrict development of the property. The boundary of the property has been determined by reference to the Ordnance Survey record. The presence of a public sewer running within the boundary may restrict further development. Anglian Water has a statutory right of access to carry out work on its assets, subject to notice. This may result in employees of the company or its contractors needing to enter the property to carry out work. Sewers indicated on the extract of the public sewer map as being subject to an agreement under Section 104 of the Water Industry Act 1991 are not an 'as constructed' record. It is recommended that these details are checked with the developer, if any. Question 7 Answer Informative Does the public sewer map indicate any public sewer within metres (100 feet) of any buildings within the property? The public sewer map indicates that there are no public sewers within metres (100 feet) of a building within the property. However, it has not always been a requirement for such public sewers to be recorded on the public sewer map. It is therefore possible for unidentified sewers or public sewers to exist within the boundaries of the property. However, on 1 October 2011 private sewers were transfered into public ownership, therefore there may be additional lateral drains and/or public sewers which are not recorded on the public sewer map but are also within metres (100 feet) of a building within the property. The measure is estimated from the Ordnance Survey record, between any building within the boundary of the property and the nearest public sewer. Sewers indicated on the extract of the public sewer map as being subject to an agreement under Section 104 of the Water Industry Act 1991 are not an 'as constructed' record. It is recommended that these details are checked with the developer. Question 8 Answer Informative Are any sewers or lateral drains serving or which are proposed to serve the property the subject of an existing adoption agreement or an application for such an agreement? Records confirm that sewers serving the development, of which the property forms part, are not the subject of an existing adoption agreement or an application for such an agreement. This enquiry is of interest to purchasers of new properties who will want to know whether or not the property will be linked to a public sewer. Where the property is part of a very recent or ongoing development and the sewers are not the subject of an adoption application, buyers should consult with the developer to ascertain the extent of public drains and sewers for which they will hold maintenance and renewal liabilities. Ref: Land off, Wilburton Road, Haddenham, ELY,

47 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 9 Answer Informative Has a Sewerage Undertaker approved or been consulted about any plans to erect a building or extension on the property over or in the vicinity of a public sewer, disposal main or drain? The company's records confirm that there is not a statutory agreement or consent in respect of building over/near a public sewer at this property. For historical reasons the company may not be aware of some agreements or consents which have been entered into by the local authority. Whilst an 'agreement' may not exist, current Building Regulation guidance permits building over/near sewers in certain circumstances. Consent without an agreement may have been issued by Anglian Water or independently by the Building Control Body. As long as the extension has a valid building regulations certificate then this should prove adequate assurance to the purchaser. Anglian Water Services Limited is obliged to maintain its sewers. If any problem were to arise, Anglian Water Services Limited would investigate the problem and has a statutory right of access to carry out work on its assets, subject to notice. This may result in employees of the company or its contractors needing to enter the property. In advance of any problem it is difficult to predict the effect the works would have on the property. Similarly, the position as to liability of both the property owner and Anglian Water Services Limited would need to be ascertained. On 1 October 2011 private sewers were transfered into public ownership, therefore there may be additional public sewers, disposal mains or lateral drains which are not recorded on the public sewer map but which may further prevent or restrict development of the property. Question 10 Is any building within the property at risk of internal flooding due to overloaded public sewers? Answer Informative The property is not recorded as being at risk of internal flooding due to overloaded public sewers. On 1 October 2011 private sewers, disposal mains and lateral drains were transferred into public ownership. It is therefore possible that a property may be at risk of internal flooding due to an overloaded public sewer which Anglian Water may not be aware of. For further information it is recommended that enquiries are made of the vendor as to any previous flooding occurances. A sewer is "overloaded" when the flow from a storm is unable to pass through it due to a permanent problem (eg. Flat gradient, small diameter). Flooding as a result of temporary problems such as blockage, siltation, collapses, and equipment or operational failures are excluded. "Internal flooding" from public sewers is defined as flooding which enters a building or passes below a suspended floor. For reporting purposes, buildings are restricted to those normally occupied and used for residential, public, commercial, business or industrial purposes. "At Risk" properties are those that the water company is required to include in the Regulatory Register that is reported annually to the Director General of Water Services. These are defined as properties that have suffered, or are likely to suffer, internal flooding from public foul, combined or surface water sewers due to overloading of the sewerage system more frequently than the relevant reference period (either once or twice in ten years) as determined by the Company's reporting procedure. Flooding as a result of storm events proven to be exceptional and beyond the reference period of one in ten years are not included on the At Risk register. Properties may be at risk of flooding but not included on the Register where flooding incidents have not been reported to the company. Public sewers are defined as those for which the company holds statutory responsibility under the Water Industry Act It should be noted that flooding can occur from private sewers and drains which are not the responsibility of Anglian Water Services Limited. This report excluded flooding from private sewers and drains and Anglian Water Services Limited makes no comment upon this matter. Question 11 Please state the distance from the property to the nearest boundary of the nearest sewage treatment works Answer Informative The nearest sewage treatment works is 0.41 kilometres to the South of the property. The name of the sewage treatment works is HADDENHAM STW (Anglian Water Services Ltd). The nearest sewage treatment works will not always be the sewage treatment works serving the catchment within which the property is situated. The Sewerage Undertaker's records were inspected to determine the nearest sewage treatment works. It should be noted, therefore, that there may be a private sewage treatment works closer than the one detailed above that has not been identified. Ref: Land off, Wilburton Road, Haddenham, ELY,

48 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 12 Is the property connected to mains water supply? Answer This enquiry appears to relate to a plot of land or a recently built property. It is recommended that the water supply proposals are checked with the developer. Question 13 Are there any water mains, resource mains or discharge pipes within the boundaries of the property? Answer Informative The map of waterworks does not indicate any water mains, resource mains or discharge pipes within the boundaries of the property. The boundary of the property has been determined by reference to the Ordnance Survey record. Question 14 Is any water main or service pipe serving, or which is proposed to serve the property, the subject of an existing adoption agreement or an application for such an agreement? Answer Informative This enquiry appears to relate to a plot of land or a recently built property. It is recommended that water supply proposals are checked with the developer. This enquiry is of interest to purchasers of properties who will want to know whether or not the property will be linked to the mains water supply. Question 15 Is the property at risk of receiving low water pressure or flow? Answer Informative Records confirm that the property is not recorded on a register kept by the water undertaker as being at risk of receiving low water pressure or flow. "Low water pressure" means water pressure below the regulatory reference level which is the minimum pressure when demand on the system is not abnormal. Water Companies are required to include in the Regulatory Register that is reported annually to the Director General of Water Services properties receiving pressure below the reference level, provided that allowable exclusions do not apply. (i.e. events which can cause pressure to temporarily fall below the reference level). The reference level of service is a flow of 9 litres/minute at a pressure of 10 metres head on the customer's side of the main stop tap (mst). The reference level of service must be applied on the customer's side of a meter or any other company fittings that are on the customer's side of the main stop tap. The reference level applies to a single property. Where more than one property is served by a common service pipe, the flow assumed in the reference level must be appropriately increased to take account of the total number of properties served.for two properties, a flow of 18 litres/minute at a pressure of 10 metres head on the customers' side of the mst is appropriate. For three or more properties the appropriate flow should be calculated from the standard loadings provided in BS6700 or Institute of Plumbing handbook. Allowable exclusions: The Company is required to include in the Regulatory Register properties receiving pressure below the reference level, provided that allowable exclusions listed below do not apply. Abnormal demand: This exclusion is intended to cover abnormal peaks in demand and not the daily, weekly or monthly peaks in demand which are normally expected. Water Undertakers should exclude from the reported DG2 figures, properties which are affected by low pressure only on those days with the highest peak demands. During the report year companies may exclude, for each property, up to five days of low pressure caused by peak demand. Planned maintenance: Water Undertakers should not report under DG2 low pressures caused by planned maintenance. It is not intended that water undertakers identify the number of properties affected in each instance. However, water undertakers must maintain sufficiently accurate records to verify that low pressure incidents that are excluded from DG2 because of planned maintenance are actually caused by maintenance. One-off incidents: This exclusion covers a number of causes of low pressure: mains bursts; failures of company equipment (such as PRVs or booster pumps); firefighting; and action by a third party. However, if problems of this type affect a property frequently, they cannot be classed as one-off events and further investigation will be required before they can be excluded. Low pressure incident of a short duration: Properties affected by low pressure which only occur for a short period, and for which there is evidence that incidents of a longer duration would not occur during the course of the year, may be excluded from the reported DG2 figures.

49 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 16 Please include details of a water quality analysis made by the water undertaker for the water supply zone in respect of the most recent calendar year Answer Informative The analysis confirmed that all tests met the standards prescribed by the 2000 Regulations or the 2001 Regulations. Anglian Water investigates all infringements of drinking water quality standards thoroughly and takes appropriate corrective actions to resolve any problems. If there was any risk to public health from the quality of drinking water supplied, the Company would inform customers immediately, advise them not to drink the water until the risk had been removed and would take appropriate steps to advise and protect their customers. The information provided above is based on a full calendar year. For more up to date and detailed information please see the water quality report provided at the back of this search. You can also visit or telephone or write to Geodesys, PO Box 485, Huntingdon, Cambridgeshire, PE29 6YB. Water companies have a duty to provide wholesome water that meets the standards of the Water Supply (Water Quality) Regulations Water quality is normally tested at the tap used for domestic consumption, usually the kitchen. However, the owner/occupier is responsible for any deterioration in water quality that is a result of the supply pipe and the plumbing within the property and results in the standards not being met. In England and Wales these regulations implement the requirements of the European Drinking Directive 98/83/EC. The 2000 Regulations impose standards for a range of parameters, which are either health based to ensure the water is safe to drink or ensure the water is aesthetically acceptable. They also require that drinking water should not contain any element, organism or substance (whether or not a parameter) at a concentration or value which would be detrimental to public health. If there are concerns that lead pipes within the property may be causing high levels of lead in your drinking water please contact your water company for further advice (Telephone Anglian Water Customer Services on: ). The water company undertakes a monitoring programme to establish water quality that includes random sampling from properties. It will notify the consumers of any failures to meet the water quality standards that are due to the condition or maintenance of the supply pipe and the plumbing within the property. Samples are taken from a random selection of addresses within a water supply zone and the results of these samples represent the zonal performance. Water Quality zones are allowed to have a population equivalent of up to 86,000 and can cover large geographical areas. There is only a small possibility that the results of samples reported were taken from the property in question. The data collected by the company is subject to external review by the drinking water inspectorate (DWI) and by local and health authorities. In addition to reviewing quality data the DWI also carry out audits during which any area of the company's operations can be examined. Question 17 Please include details of any departures, authorised by the Secretary of State under Part 6 of the 2000 Regulations from the provisions of Part 3 of those Regulations. Answer Informative There are no such authorised departures for the water supply zone. Authorised departures are not permitted if the extent of the departure from the standard is likely to constitute a potential danger to human health. Please contact your water company if you require further information. Question 18 Please include details of the location of any water meter serving the property Answer Records indicate that this enquiry relates to a plot of land or recently built property. It is recommended that the charging proposals are checked with the developer. Question 19 Who are the sewerage and water undertakers for the area? Answer Anglian Water Services Limited, PO Box 770, Lincoln, LN5 7WX, Tel: , is the sewerage undertaker for the area and Anglian Water Services Limited, PO Box 770, Lincoln, LN5 7WX, Tel: , is the water undertaker for the area. Question 20 Who bills the property for sewerage services? Answer Records indicate that this enquiry relates to a plot of land or a recently built property. It is recommended that the charging proposals are checked with the developer. Ref: Land off, Wilburton Road, Haddenham, ELY,

50 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 21 Who bills the property for water services? Answer Records indicate that this enquiry relates to a plot of land or a recently built property. It is recommended that the charging proposals are checked with the developer. Question 22 What is the current basis for charging for sewerage and water services at the property? Answer Informative Records indicate that this enquiry relates to a plot of land or a recently built property. Water and sewerage companies full charges are set out in their charge schemes which are available from the company free of charge upon request. Unless we consider it impracticable to fit a Meter, we will require a Meter to be fitted to our specification to measure the volume of water supplied for charging purposes to all Non-Household premises or to any other premises where the principal use of the premises is not as a person's home. (For the purposes of assessing whether the principal use of the premises is otherwise than as a person's home account will be taken of whether a business is registered for V.A.T. purposes at the premises.) Non-Household Customers will be charged for fitting a Meter. Non-Household Measured Tariffs will automatically apply and be fixed in respect of all Non-Household Premises to which a Meter has been fitted to our specification to measure the volume of water supplied for charging purposes. Otherwise, the Unmeasured Tariffs will apply. Mixed use premises are premises used partly as a person's house or dwelling and partly for business purposes, eg. a supply serving both a farmhouse occupied as a sole or principal dwelling and a farm; or, a shop and a flat occupied as a sole or principal dwelling. If the principal use of the premises is for business purposes, measured charges will apply as if the whole of the premises were Non-Household premises. If the principal use of the premises is as a person's sole or principal dwelling, measured charges will apply when fixed in accordance with our Meter policy for Household Customers. Otherwise, Customers will be charged unmeasured tariffs. Occupiers of Mixed Use Premises may choose whether the premises are charged under Household Charges or Non-Household Charges. Choosing to pay Non-Household Charges will not affect your statutory rights if you are occupying the premises as your home or as your sole or principal dwelling, but may otherwise affect your entitlement, eg. for a leakage rebate. If at a later date separate supplies are provided to separate parts of the premises, those parts will be charged according to their use, ie. Household or Non-Household. Question 23 Is there any easement giving Anglian Water the right of access to defined assets located within the boundary of the property? Answer Informative Records indicate that the property is subject to such an agreement. This question relates to private agreements between Anglian Water acting in a private capacity and a landowner. Such contracts may often be part of a conveyance or land transfer, or a deed of grant of easement. If there is no formal easement, then a sewer or water main may have been constructed following the service of notice under the provisions of the Public Health Act 1936, Water Act 1945, Water Act 1989 or Water Industry Act 1991 as applicable. The company does not hold copies of these notices. However, in the absence of evidence to the contrary there is a legal presumption that all matters were properly dealt with. All rights and obligations relating to sewers and water mains are now covered by the Water Industry Act Where rights exist at the boundary of the property, but we are not sure of the exact correlation, we will answer 'yes' to this question. A documentary right can exist even if the physical asset itself has not yet been laid, or has been moved, or removed. Likewise the position of the right and of the asset may differ. You may also find that an asset is protected both with contractual rights and statutory rights. Please consult your solicitor as to why this may happen, and its effects. We refer to 'defined' assets for the following reasons: Often a contract may give Anglian Water an expressed right to install and maintain assets within an area but without stating the exact position or route of such assets. Also, the law may imply rights where none have been mentioned specifically in a related contract, such as a conveyance. Finally, rights may come into being through long use. In any of these cases the rights are undefined, and although Anglian Water may need to rely on them from time to time, as we cannot map the rights accurately, we will answer 'no' to this question. Information obtainable from physical inspection (including Trial Bore Holes) overides information contained in the report. Any error in answering this question is not to be regarded as a waiver of Anglian Water's rights or title, or an agreement or representation that Anglian Water is prepared to vary or discharge any of its rights or title. As a general rule, easement widths are as follows: Pipe Diameter Width or Strip Up to 149mm 4.5m mm 6.0m mm 9.0m 750 and above 12.0m If you require a copy of an agreement please contact Savills, Trinity Court, Trinity Street, Peterborough, PE1 1DA.

51 Geodesys Commercial Drainage & Water Enquiry:B Requested: 01 July 2013 Completed: 01 July 2013 Question 24 Are there any trade effluent consents relating to this site/property Answer Informative Records indicate that there are no trade effluent consents relating to this site/property. The Trade effluent consent applies to premises in the vicinity of the premises the subject of this search, but it is for the applicant to satisfy itself as to the suitability of the consent for its client's requirements. If, in the case of any trade premises, any trade effluent is discharged without such consent or other authorisation, the occupier of the premises shall be guilty of an offence. The occupier of any trade premises in the area of Anglian Water Services Limited may only discharge any trade effluent proceeding from those premises into Anglian Water Services Limited's sewers if he does so with Anglian Water Services Limited's consent. Please note any existing consent is dependant on the business being carried out at the property and will not transfer automatically upon change of ownership. For further information, including copies of consent, please contact Anglian Water, Water Quality and Environmental Performance Department, Environmental Standards Team, Anglian House, Ambury Road South, Huntingdon, Cambridgeshire, PE29 3NZ or telephone Ref: Land off, Wilburton Road, Haddenham, ELY,

57 Your drinking water supply Drinking Water Quality Report for the Ely Public Water Supply Zone Report period: January 2013 to March 2013 Anglian Water s region is divided into 160 water supply areas called Public Water Supply Zones, each providing our customers with an excellent drinking water supply. We carry out around 146,000 tests each year on drinking water samples taken from customer taps. The number of drinking water samples we take, and the tests we carry out, are specified in the current Water Supply (Water Quality) Regulations and our regulator, the Drinking Water Inspectorate, carry out regular audits to make sure we comply with these regulations. During the period of this report, all samples taken in this Public Water Supply Zone fully met all the legal limits specified in the current Water Supply (Water Quality) Regulations. Source: Your drinking water supply comes from a groundwater source (borehole). Hardness: Your drinking water supply is classified as hard. We've included the following information to help you set your domestic appliances, the hardness has been shown in different units below: Calcium (mg/l) Calcium carbonate (mg/l) Degrees Clark ( C) Degrees French ( f) Degrees German ( dh) millimoles (mmol/l of Ca) (mg/l = milligrammes per litre or the same as parts per million) Fluoride: We don t add fluoride to your drinking water supply, but there is naturally occurring fluoride present in all drinking water supplies. Chlorine: Disinfection is important to ensure there are no harmful organisms in the water. We use chlorine to disinfect drinking water supplies. We don t add ammonia in this process, so your drinking water supply is not chloraminated. Lead: If you live in a house built before 1970, you may have lead pipework. If you think you may have lead pipework, call our Lead Advice Line on to arrange for a free lead test. Work in your area: To make sure the quality of the drinking water we supply remains excellent, we sometimes need to carry out work to ensure we continue to meet the legal limits specified in the Water Supply (Water Quality) Regulations 2000 (as amended). This work is known as a Programme of Work. Our Regulator, the Drinking Water Inspectorate closely monitors the progress of this work and will formally sign it off when it is completed. The table below shows what we are doing in your area: Parameter Programme of Work Completion Date Cryptosporidium Monitoring 30/04/2013 Lead Installation of uprated orthophosphoric acid dosing 30/09/2013 Lead Drinking water sample results: Package of measures for High Risk PWSZs, output includes replacement of lead communication pipes and customer education and awareness programme 31/03/2015 Unacceptable risk from PFOS and fuels New water source and associated treatment 31/03/2015 The results of tests carried out on drinking water samples taken from customer taps in this Public Water Supply Zone for the period are shown in the following table:

Use of polyacrylamide is tightly controlled. Alkalinity is the amount of calcium and magnesium salts dissolved in the water. Known as temporary hardness and removed by boiling. Naturally present in some water sources. Can be used in water treatment processes but is then removed. Anglian Water do not use aluminium in any water treatment process. Naturally present in most water sources. Can be added as part of the disinfection process to maintain chlorine in the distribution system (known as chloramination). Not found naturally in drinking water. Traces found in water are likely to be due to contact with brass fittings or lead solder. Low levels can occur naturally in some groundwater sources. Arsenic is removed by water treatment. Used in the petrochemical and plastics industry. May be present in water sources due to industrial pollution but is removed by treatment. One of several compounds known as poly aromatic hydrocarbons (PAHs). Coal tar was historically used to line water mains to prevent corrosion; trace levels can be found in drinking water where coal tar linings are still present.

60 Enterococci Epichlorohydrin Fluoride Gross alpha activity Gross beta activity Hardness (total) Iron Lead indicates possible contamination and requires investigation. Not found naturally in water but found in polyamine which can be used for water treatment. Use of polyamines is tightly controlled. Occurs naturally in many water sources at varying concentrations. Fluoride is added to some drinking water supplies at the request of the local Health Authority. Both of these are measured as part of the calculation of the Total Indicative Dose (TID) for radiation (see below). Hardness is due to the calcium and magnesium salts dissolved in the water. The geology of the Anglian Water area means all our water is hard. Naturally occurring in many water sources. Can be present in drinking water due to the corrosion of iron water mains. Can also be used in water treatment processes but is then removed. Lead is very occasionally found in water sources. It is more usually found in drinking water due to contact with lead pipes in properties built before Anglian Water dose phosphate to water supplies in areas where lead could leach from pipework, but the only permanent solution for householders is replacement of any lead pipework. 0.1 µg/l 1.5 mg/l 0.1 Bq/l 1 Bq/l No legal limit applies 200 µg/l 25 µg/l to Then 10 µg/l on and after 25/12/2013.

63 YOUR DEVELOPMENT SITE: Wilburton Road, HADDENHAM The information provided within this report has been generated based on the following information provided in your application form: The grid reference for the site is TL The site currently does not have planning permission and is located on a Greenfield site. The development site will contain 150 dwellings across 4.94 Hectares. The anticipated residential build rate is: Year Build rate The comments contained within this report relate to the public water mains and sewers indicated on our records. Your attention is drawn to the disclaimer in the useful information section of this report. Due to the recent adoption of private sewers in October 2011 many newly adopted public wastewater assets and their history are not indicated on our records. You also need to be aware that your development site may contain private water mains, drains or other assets not shown on our records. These are private assets and not the responsibility of Anglian Water but that of the landowner. ASSETS AFFECTED Our records indicate that we have public water mains, public foul and surface water sewers within the boundary of your development site. Additionally, it is highly recommended that you carry out a thorough investigation of your proposed working area to establish whether any unmapped public or private sewers and lateral drains are in existence. We are unable to permit development either over or within the easement strip without prior consent. The extent of the easement is provided in the table below. Please be aware that the existing underground assets should be located in highway or open space and not in private gardens. This is to ensure available access for any future maintenance and repair. This should be taken into consideration when planning your site layout.

64 Wastewater Easement Information Sewer Size (mm) Foul: 150 Surface: 300 Total Easement Required (m) 3m either side of the centre line 3m either side of the centre line If it is not possible to avoid our asset(s) then the water main and/or sewer(s) may need to be diverted in accordance with Section 185 of the Water Industry Act (1991). We have a duty to divert our sewerage infrastructure if requested to do so although this would be at your expense. You will need to make a formal application if you would like a diversion to be considered. A copy of the section 185 diversion application form can be found at /developers Anglian Water notes the proximity of this development to the Haddenham water recycling centre (WRC), from which odour emissions and noise may be detectable at neighbouring property. The treatment of wastewater is inherently odorous and needs to operate on a 24hr basis; therefore, some disturbance to adjacent property is unavoidable. However, our initial assessment indicates that this development lies beyond the range at which detectable noise and odour from the WRC operation would normally be anticipated. As such we would conclude that the risk of a loss of amenity at the development due to operations at the WRC is low and therefore this development is considered acceptable. WASTEWATER SERVICES In examining the wastewater system we assess the ability for your site to connect to the public sewerage network without causing a detriment to the operation of the system. We also assess the receiving sewage works and determine whether the sewage works can cope with the increased flow and influent quality arising from your development. Wastewater Treatment The foul drainage from this development is in the catchment of Haddenham Water Recycling Centre (WRC), which has capacity to treat the flows from your development site. Anglian Water cannot reserve capacity at this WRC and you are recommended to formally apply for a connection at your earliest convenience. Please note that capacity at the WRC can be reduced at any time due to increased requirements from existing businesses and houses, from new housing and new commercial developments as well as from environmental and regulation driven changes. Foul Sewerage Network As per your request we have assessed a gravity solution to the nearest connection point. We can confirm that this is acceptable as the foul sewerage system, at present, has available capacity for your site. The first 20 dwellings can be connected to the foul sewer that crosses the north of the site at national grid reference (NGR) TL The remaining 130 dwellings can be accommodated via a gravity connection manhole reference 6802 at the west edge of the site at NGR TL Pre Planning Report Page 3 Wednesday, 16 October 2013

65 Surface Water Disposal In principle, the proposed method of surface water disposal is acceptable to Anglian Water. It is our understanding that the evidence to confirm your site assumptions are not available. You must liaise with the Environment Agency and they must confirm acceptance of the proposed discharge, their rates may be lower and the more stringent would apply. Once the evidence has been confirmed, then a connection point would be to manhole 6853 at the west edge of the site at NGR TL Anglian Water could accept a maximum rate of 20 litres per second, however, as above the Environment Agency may have a more stringent rate. It is your responsibility to provide the evidence to support your assumptions and these will be required before your connection can be agreed. As you may be aware, Anglian Water will consider the adoption of SuDs provided that they meet the criteria outline in our SuDs adoption manual. This can be found on our website at We will adopt features located in public open space that are designed and constructed, in conjunction with the future SuDs Approving Body, to the criteria within our SuDs adoption manual. Specifically, developers must be able to demonstrate: 1. Effective upstream source control, 2. Effective exceedance design, and 3. Effective maintenance schedule demonstrating than the assets can be maintained both now and in the future with adequate access. Our preference is that the Local Authority is requested to adopt in the first instance as duty will pass to them in future legislation. Consequently as part of your submission, evidence will need to be provided to show that you have approached the local authority. If you wish to look at the adoption of any SuDs then an expression of interest form can be found on our website at Wastewater Budget Costs It has been assumed that the onsite foul network will be provided under a section 104 Water Industry Act application. It is recommended that you also budget for both infrastructure charges and connection costs. The 2013/14 charges are: Infrastructure Charge S104 Supervision and inspection costs S104 Surety costs per connection 2.5% of estimated construction costs 10% of estimated construction costs Pre Planning Report Page 4 Wednesday, 16 October 2013

68 USEFUL INFORMATION Sustainable Drainage Systems: Many existing urban drainage systems can cause problems of flooding, pollution or damage to the environment and are resilient to climate change in the long term. Therefore our preferred method of surface water disposal is through the use of Sustainable Drainage Systems (SuDS). SuDS are a range of techniques that aim to mimic the way surface water drains in natural systems within urban areas. For more information on SuDS, please visit our website at We also recommend that you contact the future SuDS Approving Body (SAB) for the area to discuss your application. Water Industry Act Key Wastewater Sections: Section 98: This provides you with the right to requisition a new public sewer. The new public sewer can be constructed by Anglian Water on your behalf. Alternatively, you can construct the sewer yourself under section 30 of the Anglian Water Authority Act Section 102: This provides you with the right to have an existing sewerage asset vested by us. It is your responsibility to bring the infrastructure to an adoptable condition ahead of the asset being vested. Section 104: This provides you with the right to have a design technically vetted and an agreement reached that will see us adopt your assets following their satisfactory construction and connection to the public sewer. Section 106: This provides you with the right to have your constructed sewer connected to the public sewer. Section 185: This provides you with the right to have a public sewerage asset diverted. Details on how to make a formal application for a new sewer, new connection or diversion are available on our website at application-form or via our Developer Services team on Private Sewer Transfers: Sewers and lateral drains connected to the public sewer on the 1 July 2011 transferred into Water Company ownership on the 1 October This follows the implementation of the Floods and Water Management Act (FWMA). This included sewers and lateral drains that were subject to an existing Section 104 Adoption Agreement and those that were not. There were exemptions and the main non-transferable assets were as follows: Surface water sewers and lateral drains that did not discharge to the public sewer, e.g. those that discharged to a watercourse. Foul sewers and lateral drains that discharged to a privately owned sewage treatment/collection facility. Pumping stations and rising mains will transfer between 1 October 2011 and 1 October The implementation of Section 42 of the FWMA will ensure that future private sewers will not be created. It is anticipated that all new sewer applications will need to have an approved section 104 application ahead of a section 106 connection. Pre Planning Report Page 7 Wednesday, 16 October 2013

69 Encroachment: Anglian Water operates a risk based approach to development encroaching close to our wastewater infrastructure. We assess the issue of encroachment if you are planning to build within 400 metres of a Sewage Treatment Works or, within 15 metres to 100 metres of a pumping station. We have more information available on our website at encroachment.aspx Locating our assets: Maps detailing the location of our water and wastewater infrastructure including both underground assets and above ground assets such as pumping stations and treatment works are available from All requests from members of the public or non-statutory bodies for maps showing the location of our assets will be subject to an appropriate administrative charge. We have more information on our website at: Summary of charges: A summary of this year s water and wastewater connection and infrastructure charges can be found at /charges/ Disclaimer: The information provided within this report is based on the best data currently recorded, recorded within the last 12 months or provided by a third party. The position must be regarded as approximate. If there is further development in the area or for other reasons the position may change. The accuracy of this report is therefore not guaranteed and does not obviate the need to make additional appropriate searches, inspections and enquiries.
