AECOM 15 Commerce Valley Drive West, Floor 7 95 886 722 tel Markham, ON, Canada L3T 7W3 95 886 9494 fax www.aecom.com Technical Memorandum To Martin Pendlebury, Kolsoom Motamedi (Region of Peel) Page 1 of 1 CC Subject From Chris Hamel (AECOM) Water Design Criteria and Starting Point Review Miriam Polga Date December 5, 211 Project Number 6216517 This technical memorandum provides a review of the Region s existing water design criteria to determine the criteria to be used in the 212 Peel Region Water and Wastewater Master Plan. In addition, the document provides an overview of the methodology for determining future water demand projections. This technical memorandum is structured as follows: 1. Introduction 2. Existing Water Design Criteria 3. Historical Demand Analysis 4. Starting Point Methodology 5. Summary and Recommendations The goals of this review include: Determine if the existing water design criteria is appropriate for the long term planning and design of the Region s water system Identify any considerations or changes needed moving forward 1. Introduction The Region of Peel has engaged AECOM to update the Water and Wastewater Master Plan. As part of this project, AECOM undertook a review of the water design criteria, the derivation of the starting point to represent historical consumption, and a sensitivity analysis on future demand projections. This review is common practice within a Master Plan study and ensures that the projected water demands are not only accurate but also reflect new trends to support decision making for the sizing and timing of future infrastructure including pipes and facilities. 2. Existing Water Design Criteria Table 1 shows the current water design criteria used at a master planning level within the Region of Peel. M1-211-11-3-Final Wdc Review Peel -Final

Page 2 Memorandum December 5, 211 Table 1 Existing Water Design Criteria Used within the Peel Region Type Average Day Demand Max Day Peaking Factor Residential 28 L/cap/d 2. Employment 28 L/emp/d 1.4 Historical data demonstrates that average day flows equated to 28 L/cap/d for residential and 417 L/cap/d for equivalent Industrial / Commercial / Institutional (ICI) population. The equivalent area-based ICI consumption equates to approximately 13,5 L/ha/d. The combined maximum day peaking factor was calculated at 1.54, based on historical max day versus average day plant production data. Based on the format of planning projections received from the Region of Peel, it is considered appropriate to utilize the employment (ICI) design criteria as a function of employees. Based on employment land criteria for lot coverage and employee density, it was determined using an employment density of 48 employees/ha, that the employment consumption rate equates to 28 L/emp/d. New development can often generate higher water requirements, for uses such as new sod watering and due to changes in resident demographics and water use patterns. In the previous Master Plan Update, potential short term water demand criteria for new development was identified and is summarized in Table 2. The higher peaking factor used for new ICI development makes the max day demand criteria for ICI comparable to the historical max day flows for ICI. Table 2 Potential Short Term Water Demand Criteria for New Development Type Average Day Demand Max Day Peaking Factor Residential 49 L/cap/d 2. ICI 9,123 L/ha/d 2. This short term water demand criteria was utilized for isolated analyses such as the Northwest Brampton analysis. Nevertheless, over the long term, it would be inappropriate to use this elevated value considering that the water use is lower once residents are established in their home and don t have higher requirements and it is also estimated that water use would ultimately be decrease through water conservation programs and other factors attributed to declining rates of consumption. As such, for the purposes of projecting long term water requirements in the Master Plan, the water demand criteria in Table 1 will continue to be utilized. 2.1 Design Criteria for System Components and Operation The following sections describe the existing design criteria for the water system s components and operation, including pumping, storage, transmission, distribution and treatment capacity. 2.1.1 Pumping Capacity Pumping stations are rated on their firm capacity to supply water. In the Peel system, the traditional approach has been to establish firm capacity based on the largest pump out of service between the M1-211-11-3-Final Wdc Review Peel -Final

Page 3 Memorandum December 5, 211 stations servicing the east and west sub-zones given that, typically, multiple stations supply each pressure zone. However, based on system performance and recent facility implementation requirements, it is recommended that the traditional pumping station firm capacity with the largest pump out of service for each pumping station be utilized. For each pressure zone, the east and west trunk pumping stations must provide local peak hour demands in the immediate serviced zone and have sufficient capacity to transfer maximum day demands for the subsequent zones to the north. 2.1.2 Storage Capacity In Peel, reservoir storage capacity at each pumping station is based on typical MOE criteria and fire underwriter s survey criteria as identified. Equalization storage at 25% of the maximum day demand for the lower pressure zone at the reservoir s Hydraulic Grade Line (HGL) Fire storage in accordance with the Standard of Municipal Fire Protection of the Canada Underwriters Association. Typically 33 L/s for 4 hours in each zone Emergency storage at 25% of the equalization plus fire storage for the lower pressure zone at the reservoir s HGL. However, as outlined in the previous Master Plan Update, given that the existing Peel system typically operates under pumped supply, the reservoirs do not typically supply the pressure zone at the reservoir s HGL, but do however float the lower zone and control the system s operating pressure. As such, the typical storage capacity criteria is also cross-referenced against storage volumes required for the pressure zones supplied by pumping from the given facility. The northern pressure zones in the Peel system operate under slightly different circumstances, as there is no floating storage to support meeting the current system demands. Therefore the previous Master Plan Update provided for an additional 5% of the average day demand over and above the standard calculation within the emergency storage for the pumped zone. The additional equalization storage was identified for the Alloa and North Brampton facilities since there was no floating Zone 6 storage identified. In the last Master Plan Update, it was noted through operating records, that it has been difficult to maintain reservoir levels and maintain typical operating procedures, particularly in the northern zones. This may be a result of insufficient storage volume or delayed implementation of system upgrades (including new facilities and capacity upgrades). Following on from these recommendations and based on the previous Master Plan Update, it was recommended that floating storage meeting MOE guidelines be provided for Zones 6 and 7. 2.1.3 Capacity The trunk capacities are required to convey the total pumping capacity requirements of the receiving pumping station to the north. As noted, this capacity is based on the component of the peak hour demand for the local zone and the maximum day demand requirements for each subsequent zone to the north. M1-211-11-3-Final Wdc Review Peel -Final

Page 4 Memorandum December 5, 211 Theoretical capacities have been approximated using capacity calculations with a reasonable allowable head loss. For larger s, a factor of 1.5 m/km of headloss has been typically used. Further refinement of capacities was undertaken using the existing Peel hydraulic model. Additional criteria developed with Peel staff and utilized to establish existing and future Transmission Main capacities are as follows: The s must be capable of transferring flow within acceptable HGL and typically below 1 psi The s are typically fed from the low lift pumps which also directly feed the local distribution system. As such, maximum flow is based on current pump capacities and pressure head and the need to operate these pumps within acceptable HGL Velocities within the s should be maintained below 2 m/s 2.1.4 Distribution Capacity The distribution system is sized to convey the greater of peak hour flows or maximum day plus fire flows. Within each pressure zone in the distribution system, the range of acceptable pressures under normal conditions is approximately 4 psi (275 kpa) to 1 psi (69 kpa). Under fire flow conditions, it is acceptable for pressures to drop to 2 psi (14 kpa). 2.1.5 Treatment Capacity Water treatment capacity is based on providing maximum day water demand requirements. Plant expansions have been traditionally scheduled on a just in time basis. Additional capacity has been scheduled and installed in steps based on growth projections and in order to stagger capital expenditures. With potential fluctuations in demand requirements and the potential fluctuations in plant capacities due to operating conditions, equipment performance and emergency conditions, it has been noted that plant capacity can be reached sooner than anticipated. It has been determined, that scheduling of plant expansions should be based on, where possible, not exceeding approximately 85-9% of full capacity. This approach should establish scheduling the future expansions before water demand projections meet available capacity. M1-211-11-3-Final Wdc Review Peel -Final

Page 5 Memorandum December 5, 211 3. Historical Demand Analysis 3.1 Average Day Demand Historical demand data as well as population and employment data was reviewed for the years 1999 to 21. In order to determine the consumption trends within the Region of Peel, the supply to York Region was subtracted from the flow data prior to the analysis being undertaken. Population and employees figures for the years 26 to 21 were taken from the SGU (Small Geographic Unit) data supplied by the Region. The 21 population and employment figures were taken from the previous Master Plan Update and interim years were interpolated using the 21 and 26 population and employment figures. It was also assumed that residential and employment consumption would continue to be the same (28 L/cap/d or L/emp/d). The average day per capita/employee consumption for each year and each plant were calculated using the population and flow datasets. The results are presented in Figure 1. Figure 1 Graph of Average Day Consumption for Residential and Employees in South Peel 4 Consumption L/cap/d 38 36 34 32 3 28 26 South Peel Lorne Park Lakeview South Peel Trendline 24 22 2 1998 2 22 24 26 28 21 Year It can be seen from Figure 1 that the current trend of water consumption is declining, however there are peaks occurring within this trend which are likely to be caused by warmer years. The 5- and 1- year average day per capita consumption are summarized in Table 3.

Up until 211, the greatest maximum day value on record was 28, at a combined total actual max day value of 95.1 MLD. Recent flow records show that 211 has surpassed this value at 976.5 MLD.

The maximum day peaking factor is the ratio between the maximum day WTP flows and the average day WTP flows. Max day peaking factors were reviewed for the South Peel system. The Region currently uses separate residential and ICI peaking factors for projecting future demands. In order to compare the observed peaking factors at the plants with the Region s current peaking factor, a composite peaking factor was calculated using historical daily flows and maximum day flows at the plants. This is shown in Table 5 as the Historical 5 and 1-year Average. Similarly, a combined peaking factor was also calculated by utilizing the Region s current design criteria to determine the M1-211-11-3-Final Wdc Review Peel -Final

Page 7 Memorandum December 5, 211 average day and maximum day demands and then back calculate the ratio. Table 5 shows these values under the Calculated 5 and 1-year Average.

This is reasonably expected and is considered beneficial in terms of providing the flexibility to provide a security buffer when projecting future water demands. 4. Starting Point Methodology The approach moving forward is based on establishing a yearly starting point, calculated from historical flows, and projecting growth flows from this starting point forward. Projected water demands will be determined using the planning data for residential and non-residential users and applying the design criteria. Under this approach, the design criteria will be applied to the residential and employment growth only and added to the starting point to project interval year flows. As such, the design criteria must estimate what will be consumed/generated and not necessarily what was consumed/generated. An overall guiding principle for the design criteria is to ensure that the flow projections are adequately predicted with an appropriate level of safety and risk management. This is to ensure that the infrastructure has sufficient capacity to meet the servicing requirements and that the timing of key infrastructure does not compromise operation of the facilities or impede planned and approved growth. On this basis, for Master Planning purposes, the design criteria should reflect a total water production need which includes consumption and non-revenue water use. As a basis for projecting future demands at the treatment facilities, a baseline 21 maximum day demand was calculated at each WTP using historical demands. Equivalent per capita consumption was calculated for each year by dividing the year s maximum day demand production by the year s population (based on the planning data). An average per capita consumption was calculated for each plant over the last five and ten years. This represents the 5-year Rolling Average and 1-year Rolling Average. The intent is to update these rolling averages every year moving forward. M1-211-11-3-Final Wdc Review Peel -Final

Page 8 Memorandum December 5, 211 The 21 Max Day Starting Point was defined as the 211 Serviced Population multiplied by the 5- year or 1-year Rolling Average. Residential and employment growth was then added to this baseline using the water design criteria presented in Table 1. Historically the Region has applied the design criteria directly to the population and employment data to determine the water demand projections. The rolling average methodology will take into account yearly fluctuations between dry/warm years and wet years (In dry/warm years consumption will be higher due to increased water usage). A sensitivity analysis was done on the projected demands to 231 by comparing different methodologies and evaluating its impact on the 231 demands. Six scenarios were reviewed using the 27 Master Plan demand calculation methodology and the rolling average methodology and applying different design criteria to each. The scenarios are described as follows: 1. SGU planning data x 28 L/cap/d 2. SGU planning data x 275 L/cap/d 3. 5-yr Rolling Average Starting Point + 28 L/cap/d x Growth (SGU planning data) 4. 5-yr Rolling Average Starting Point + 275 L/cap/d x Growth (SGU planning data) 5. 1-yr Rolling Average Starting Point + 28 L/cap/d x Growth (SGU planning data) 6. 1-yr Rolling Average Starting Point + 275 L/cap/d x Growth (SGU planning data) York Region has an agreement with the Region of Peel which allows them to take a maximum daily volume. flows to York were subtracted from the plant s production data to obtain a maximum day demand within the Region of Peel. This was used to calculate the 5-year and 1-year rolling averages for each of the plants and the overall system. To determine the starting point, these averages were added to the maximum allowable demand for York Region as per the current agreement. The Region s current max day peaking factors were used in this analysis. The results are presented in Table 6.

The max day demand flows at the plants are typically observed during the summer months; therefore we were able to determine a 211 starting point using summer 211 measured plant flow data. The recorded flow for 211 is now the highest on record, and using the proposed starting point methodology, it was noted that the projected starting point demand is very close to the measured flow which also matches well with the 211 demand projected from the 21 starting point.

It also shows how the calculated 21 starting point is between 12% and 2% higher than the actual 21 plant production and that the calculated 211 starting point is very close to the actual production observed at the plants under max day conditions. This indicates that the proposed methodology provides a level of reasonable accuracy in obtaining a starting point which is to be used in projecting demands to 231 and potentially build-out..

Page 1 Memorandum December 5, 211 5. Summary and Recommendations 5.1 System Components Design Criteria The 212 Region of Peel Water and Wastewater Master Plan will be the 4th generation of a line of Master Plans and Master Plan Updates dating back to 1999. Design criteria has been an element that has undergone review under each of these studies and has evolved as a result over the years. However, over the past 12 years, design criteria governing the planning, design, and operation of system components, such as pumping stations, storage facilities, transmission mains and distribution system has remain unchanged. This is primarily due to the fact that the design premises have resulted in efficient system operation, as well as proper scheduling and implementation of infrastructure improvements to service capacity requirements in a timely manner. As such, it is recommended that the existing design criteria for system components be maintained for the 212 Peel Region Water and Wastewater Master Plan Update. 5.2 Water Consumption Design Criteria Review of the water consumption criteria for projecting future water demands was also undertaken. From the analysis undertaken for the average day demand criteria, it can be seen that on a Region wide level the 5- and 1-year averages of 275 L/cap/d and 28 L/cap/d are similar to those presently in use by the Region of Peel, 28 L/cap/d for residential demand and 28 L/emp/d for employment. This confirms that the existing consumption criteria is representative of historical trends in the Region and supports validation of the criteria. As such, it is recommended that the Region continue to utilize the average day consumption design criteria of 28 L per person/employee per day. The existing residential and employment max day peaking factors are 2. and 1.4, respectively. The max day peaking factors that are used by the Region are higher than those that have been observed in the last 1 years on a Region wide basis. The existing max day peaking factors, although higher than the observed trends, should be retained as they will take into consideration the effects of warmer-than-average summers. 5.3 Methodology for Projection of Future Water Demands A review and sensitivity analysis on various methodologies for projecting future water demands was undertaken to determine the most appropriate methodology for the 212 Peel Region Water and Wastewater Master Plan Update. From the sensitivity analysis performed on the starting point it can be seen that the scenarios which apply the 5-year rolling average have the lowest projected demand. Results from Scenarios 1 and 2 indicate that a reduction in the design criteria has a very limited impact on the total projected demand. Furthermore, the rolling average methodology has the largest impact on the demand projections, due to the fact that the per capita average daily consumption over the last 1 years is declining and the observed max day factors are lower than those currently in use by the Region. This occurs because the per capita average daily consumption over the last 1 years is declining and the observed max day factors are lower than those currently in use by the Region.

Page 11 Memorandum December 5, 211 For the 212 Peel Region Water and Wastewater Master Plan Update it is recommended that a 211 starting point of 955.17 MLD which corresponds to the 5-year rolling average methodology (Scenario 3). The 5-year rolling average was considered more appropriate than the 1-year average for the reason that the 1-year rolling average takes into account additional historical data when consumption was higher than today and therefore would produce overly conservative demands. The 5 year rolling average will enable an accurate baseline demand to be established. M1-211-11-3-Final Wdc Review Peel -Final

Appendix 3F Unit Costs

AECOM 15 Commerce Valley Drive West, Floor 7 95 886 722 tel Markham, ON, Canada L3T 7W3 95 886 9494 fax www.aecom.com Memorandum To Martin Pendlebury and Kolsoom Motamedi (Region of Peel) Page 1 CC Subject Update of Linear Unit Rates From Fiona Macdonald (AECOM) Date July 24, 212 Project Number 6216517 1. Introduction This memorandum summarizes the peer review of linear unit rates carried out as part of the 212 Region of Peel Water and Wastewater Master Plan. It summarizes the results of the review and the subsequent recommended adjustments to the rates. The proposed unit rates will be used as a basis to develop estimates for each of the projects identified in the Master Plan. The rates were initially developed as part of the Quick Start program at the beginning of the Master Plan project. 1 As the Master Plan focuses on trunk water and wastewater infrastructure, the emphasis of the peer review was on the unit rates for this size of infrastructure. 2. Peer Review The unit rates used in the Quick Start program were provided to Estimating Services Incorporated (ESI) for review. The focus of the review was to determine whether the Master Plan unit rates provided a sound basis for project estimates. As part of the review, ESI developed their own unit rates for comparison, based on consultation with suppliers as well as recent project experience. These rates are provided in Appendix C of this memorandum. ESI observed that recent tenders have varied widely in price. The ESI rates are an average case for May 212, and do not include contingency, restoration, disinfection or traffic management. The ESI and Quick Start unit rates were compared to determine if the Quick Start values fell within a reasonable range of the ESI values. It is not expected that the rates should be identical, as ESI rates are based on May 212 construction conditions and are not necessarily conservative enough for a Master Planning study; whereas the Quick Start rates were developed to represent general unit rates in 211, for Master Planning purposes. The rates were not directly comparable (for example, AECOM rates included for restoration and appurtenances), therefore the extra items were removed from the AECOM rates so that a fair comparison could be made. The following specific comments were made: 1 Memorandum - Peel Quick Start. AECOM, August 211. M-212-7-24-Mp Unit Rate Update Draft-6216517M-212-7-17-MP Unit Rate Update Postqa-6216517

Page 2 Memorandum The individual project costing sheets provided an appropriate level of detail for project costing. AECOM pipe supply and install rates for forcemains and watermains did not allow for any extra factors. ESI recommended that 2% should be allowed for short pipes, restraints and closures, and that in cases with additional fittings required (elbows, chambers, etc) an additional 3% markup should be applied. AECOM installation costs were based on a percentage of pipe cost. This resulted in installation costs that are relatively low for smaller pipe diameters. AECOM and ESI excavation volume assumptions were different for wastewater pipes. 3. Master Plan Unit Rates The results of the peer review were used to adjust the 211 Quick Start unit rates for use in the 212 Master Plan. The following adjustments were made: The pipe supply rates for forcemains and watermains were increased by 2%. The 3% factor will be be applied in the individual project costing sheets where appropriate. A minimum installation cost of $4/m was used to prevent unrealistically low installation costs being carried. The formulae used to calculate excavation volume were adjusted. For the 5m deep wastewater pipe, a 5m deep trench box was assumed i.e. the excavated volume was calculated as depth x width i.e. 5m x width, per metre of pipe. For the 1m deep wastewater pipe, a 5m deep trench box was assumed, with the next 5m banked at 1:1 slope. This resulted in lower excavation volumes for the 5m deep pipes, and higher volumes for the 1m deep pipes. The rates will be adjusted to 213$ when the inflation factor is available. Appendix A includes the recommended Master Plan Unit Rates, while Appendix B compares these rates with those used in the Quick Start. It is noted that these rates have changed significantly since the 27 Master Plan. Factors that have contributed to the change in unit costs include inflation, the fact that pipe pricing is considerably higher now, excavation and granular costs have increased, and increasing gas prices have had an effect in many areas. 4. Conclusion It is the opinion of AECOM and ESI that the revised unit costs are appropriate for Master Planning purposes, and within the range of costs to be expected on competitively tendered jobs in the Region of Peel, taking into account the fact that other add-ons may be applied on a project specific basis e.g. for urban areas, difficult construction conditions, and project-specific considerations. 5.
