Adv M Mbatha Mr P Du Toit Municipal Manager Deputy Manager Water & Sanitation Ehlanzeni District Municipality Ehlanzeni District Municipality Executive Summary Sibange Bulk Water Scheme serves several villages of Nkomazi Local Municipality. The scheme is located in the South-East of the Ehlanzeni District Municipality (EDM). The supply area is predominantly rural with yard stand pipes and ventilation improved pit (VIP) toilets. Current and projected population of the study area is as presented below: Table 1: Executive Summary: Population Projection 2014 2017 2022 2027 2032 2037 Settlement Name Pop Pop Pop Pop Pop Pop Sibange 3 650 3 817 4 112 4 430 4 772 5 141 Sibange A 1 214 1 270 1 368 1 473 1 587 1 710 Madadeni 8 317 8 697 9 369 10 093 10 873 11 714 Sikhwahlane 3 709 3 879 4 178 4 501 4 849 5 224 Ntunda 5 478 5 728 6 171 6 648 7 162 7 715 Phakama 4 920 5 145 5 542 5 971 6 432 6 929 Mgobode 12 398 12 964 13 966 15 046 16 209 17 461 Magudu 4 920 5 145 5 542 5 971 6 432 6 929 Total 44 607 46 644 50 249 54 133 58 316 62 823 From the inception and scoping studies, indications are that the water demand in the study area has exceeded supply and existing system capacity. The study area receives its water from different schemes which are overloaded due to high demand. Calculated summer peak demand for 2017 is 8Ml/d and projected demand for 2037 is 11Ml/d. Existing Water Treatment facilities within the scheme area have a total capacity of 5.3Ml/d, which is less than the current calculated demand for the entire scheme. There is a need to increase water supply into the Sibange scheme so as to meet the demand and to stop the water rationing which is currently being implemented. Nkomazi Local Municipality is authorised to draw 5,820,800m3/a from the Komati River for the Masibekela WTW, this abstraction volume is as a result of combining the different licenses for areas covered by the Sibange Bulk Water Scheme. Nkomazi LM will have to apply for one license for the Sibange Bulk Water Scheme which will combine all available licences into a single one. Below is a summary of the projected water demand for the twenty year study period: Table 2: Executive Summary: Demand Projection Year Population AADD – Ml/d GAADD – Ml/d SPD – Ml/d 2017 46 731 4.39 5.56 8.34 2027 54 133 4.99 6.31 9.46 2037 62 940 5.89 7.45 11.18 The above allocation (5,820,800m3/a) allows for an abstraction of 15.95Ml/d. The allocation when compared with the Masibekela WTW's 2037 GAADD (14Ml/d) shows that the above licenses will be adequate for the proposed full development. However, there will be a need for Nkomazi Local Municipality to apply for one license which combines the available licenses into a single one. LCE is to assist Nkomazi Local Municipality with the application for combining the available licenses into one. Below is the phasing for the proposed works: i | P a g e Sibange Bulk Water Scheme IRS Lubisi Consulting Engineers Table 3: Executive Summary: Project Phasing Phase Description 1 - Construction of 7Ml/d WTW 2 - Construction of Pipelines and Booster Pump Stations 3 - Construction and Upgrade of Reservoirs 4 - Construction and Upgrade of Elevated Storage Tanks The preliminary designs were prepared encompassing the regional scheme concept and viability. This report covers the implementation readiness state of the project. Upgrading of the bulk water supply infrastructure consisting of Masibekela Water Treatment Works, bulk pipelines, pump-stations and storage reservoirs will be implemented in phases as presented above, over the 20 year period aligned to the projected demand patterns. The estimated cost for the entire project is R105 886 805, 18 (VAT Inclusive).
