48Ward 4, 5, 6 & 7:A water project for 14 villages in the Tombo area, serving a population of approximately 20000people was recently completed and handed over to the Local Authority on 01 February 2002. 13 Ofthese villages are connected to the bulk supply, fed from the Umgazi River extraction, and theremaining one from a stand alone spring. Management of the system has been contracted out toWSSA until end December 2001. Their contract has subsequently been extended to end March 2002when the Local Authority hopes to have a technician employed. Port St John‟s municipality is theWater Services Provider to these 18 villages and Ward 3 and plans to train people this being a BOTproject.The current project started January 2002 and is earmarked for completion by 17 July 2002. Theproject is being funded by DWAF and the European Union (EU) in the amount of R5,5 mil. Fourvillages with a total current population of approximately 5600 people will benefit from this project.The existing purification plant, that is rated at 13l/s and is currently being upgraded to 22l/s underthe current project.The Tombo Municipal Centre consisting of a clinic, art & culture center, entrepreneur center, and amunicipal office is the only metered supply on this scheme. All schemes has been designedaccording to Level 1 standards, but constructed to RDP (Level 3) standards.The Local Authorities have requested to include an additional village under the current four villageextension, as it could easily be gravitated from the mentioned extension at a minor cost.Ward 8, 1 & 2:Being partly serviced, a technical report was recently compiled for a regional water scheme (namedGqubeni, although only serviced in later phases) that would benefit 82 villages whilst only 6 villageswill form part of Phase 1.The proposed regional water scheme is based on the abstraction of raw water from the MzimvubuRiver approximately 17km from the sea where the supply is non-tidal and non-saline, pumping to awater purification works, a reservoir situated relatively high and gravitation pipe lines to theindividual villages. The scheme can in future be extended by linking up nearby villages withoutsignificant capital investigation.According to a recent study, it was determined that the raw water source (Mzimvubu River) shouldbe sufficient to provide water to the present (Phase 1) and the total development of 82 villages(Phase 2). The river water, at the proposed abstraction point, was analyzed and seems to be freefrom sea water contamination. The suitability of the water source (Mzimvubu River) is subject to theapproval be DWAF of an application to abstract water.It is planned to design all pipework for a 20 year horizon (100l/p/d) and the balance of the works fora 10 year horizon (60l/p/d).A borehole scheme as an alternative raw water source was evaluated, but the widespread location ofthe villages and the variability of an underground water source does not proof sustainable over a 20year period. Existing borehole schemes are presently in disuse.Port St. John‟s Integrated Development PlanChapter 2: Analysis
