1 R I C H M O N D I C H M O N D P I P E L I N E Planning No Project No. UI105 Project Status Design (as at January 2011) Project Description In 2005 the Richmond Municipality requested that Umgeni Water consider supplying potable water to the town of Richmond as the existing water supply systems were proving problematic and unsustainable. Umgeni Water has thus proposed the construction of a pipeline from its 61 Pipeline system to serve the town. The project will serve the potable water demands of the greater Richmond area (initially 8.3Ml/day and ultimately 14 Ml/day) and will also tie into Umgeni Water s existing Thornville sub-system (Section 5.2.1), which is currently served from the Thornville Pump Station situated on the 61 Pipeline between ED2 and Umlaas Road. The project will be fed off the 61 Pipeline downstream of the ED4 take-off. A new pump station is required to lift the water to a new reservoir (Liliefontein Reservoir) sited near Thornville. The proposed Richmond Pipeline will run along the R56 main road to Richmond (Figure 7.14). The existing Thornville Pump Station will be decommissioned and the rising main with revert to a back feed gravity main once the Richmond Pipeline is in operation. The pipeline will terminate at the municipal reservoir that serves Richmond. Key information on this project is summarised in Table Table 7.15 Project information: Richmond Pipeline. Project Components: Capacity: m long section of 450 mm diameter pipeline and a new booster pump station. 27 Ml/day. Institutional Arrangements nts Umgeni Water will own, operate and maintain the Richmond Pipeline infrastructure and will sell potable water from this system to The Msunduzi Municipality and Umgungundlovu District Municipality as per existing bulk water supply agreements. Beneficiaries ies The consumers in The Msunduzi Municipal area and in the Richmond Municipality will benefit from this project. Implementation The construction duration of this project is anticipated to be two years. The total cost is anticipated to be R 181 million at 2010 prices. 366

3 U M L A A S M L A A S R O A D R E S E R V O I R U P G R A D E Planning No Project No. Project Status Design (as at January 2011) Project Description Umlaas Road Reservoir initially served as balancing storage for the Umlaas Road WTP. The WTP was decommissioned in 2002 as sufficient potable water could be transferred to the Umlaas Road demand node via the 61 Pipeline. The reservoir complex was retained and currently serves the Outer Western areas of ethekwini Municipality via the 57 Pipeline and the Eston/Umbumbulu and Lion Park pipelines. The reservoir site is situated to the east of the N3 National Road, just north of the N3-R603 interchange (Figure 7.15). The reservoir complex consists of two separate reservoirs, viz. the original 9 Ml reservoir and a later 45 Ml reservoir. The reservoir complex currently serves as both a break pressure and balancing storage facility and can be supplied from Midmar WTP via the 61 Pipeline and from D.V. Harris WTP via the recommissioned 53 Pipeline. It is necessary to provide at least 15 hours of balancing storage at Umlaas Road in order to cope with the peak demands placed on the supply system by the downstream consumers. It is therefore recommended that an additional 45 Ml reservoir be constructed in advance of the commencement of the proposed Western Aqueduct load transfer in This will ensure that there is sufficient storage in place to accommodate the load transfer until at least 2022, by which time the Western Aqueduct demand should have been transferred across to the Mkomazi Water Project (Section 7.2.1). Key information on this project is summarised in Table Table 7.16 Project information: Umlaas Road Reservoir Upgrade. Project Components: Capacity: New 45 Ml reservoir. 45 Ml. Institutional Arrangements Umgeni Water will build, own, operate and maintain all water supply infrastructure pertaining to this project. Beneficiaries The upgrade to the Umlaas Road Reservoir Complex will benefit all consumers downstream of the reservoir. These beneficiaries are primarily the ethekwini Municipality, but also include consumers within the Mkhambathini Municipal areas of Umgungundlovu District Municipality. Implementation The construction duration of this project is anticipated to be one year. The total cost is estimated to be R 81 million at 2010 prices. 368

These local municipalities fall within the jurisdiction of the umgungundlovu District Municipality (UMDM). The bulk water supply to the Greater Eston area as depicted in Figure 7.16 requires three off-takes on the Eston-Umbumbulu Pipeline. The first off-take will supply the umacalagwala area. The second off-take will supply the following areas: Esigodini/Gulube Ismont Mpangisa Embuthweni Inhlazuka Ukhalo The third off-take will supply the Ogagwini area. Key information on this project is summarised in Table Table 7.17 Project information: Greater Greater Eston BWSS. Project Components: Capacity: 19km of 350mm diameter pipe 16km of 200mm diameter pipe 19km of 160mm diameter pipe 14km of 110mm diameter pipe 1 Break Pressure Tank 3.5 Ml Reservoir 2 Pump Stations Scheme to accommodate ultimate demand of 4.4 Ml/day Institutional Arrangements The scheme is jointly funded by DWA, Umgeni Water and Umgungundlovu District Municipality through its MIG allocation. The proposed scheme will be operated and maintained by Umgeni Water. Bulk water contracts will be entered into with Umgungundlovu District Municipality. 370
