Heritage Cases

At present the bulk of Mandlakazi Bulk Water Supply Scheme water is sourced from Jozini Dam (Pongolapoort). Water supply is currently abstracted via privately owned infrastructure and pumped to the existing Mandlakazi Water Treatment Works (MWTW). When the Mandlakazi raw water demand exceeds 10 Ml/day the privately owned infrastructure will not have sufficient capacity, and as such, the ZDM will require its own infrastructure to abstract and transfer water from the Pongolapoort Dam to ensure adequate supply to the Mandlakazi WTW. In order to reduce the risks associated with relying on a private entity for water supply to supply raw water for basic human consumption, the Zululand District Municipality (ZDM) has there proposed the development of their own dedicated raw water supply to the Mandlakazi WTW. The overall aim is to provide rural communities and homesteads of Mandlakazi with a reliable bulk potable water supply as there is currently limited and rudimentary supply infrastructure. The project therefor provides a reliable link for the passage of raw water from Jozini Dam to the Mandlakazi Water Treatment Works. The project involves the installation of 30km of bulk pipeline from within the Pongola Nature Reserve at 27°30'27.18"S32° 0'11.64"E and will supply the Mandlakazi Water Treatment Works in the south at end point 27°40'49.86"S 31°54'58.33"E. The proposed 30km pipeline will comprise a 1000mm PVC-o rising main from the new abstraction works to the Mandlakazi WTW. The upstream bulk pipeline infrastructure will traverse 13 watercourses, 12 of which are non-perennial, and the Mkuze River being the only perennial river. The Mkuze River crossing will comprise the construction of a new stilted pipe bridge over the Mkuze River, and the alignment will be to the west of the existing road bridge. The proposed infrastructure will include scour, air valve and isolation chambers at predetermined locations along the proposed alignment. An interim reservoir and Interim Pump Station is proposed near the midpoint at 27°38'28.95"S 31°59'13.03"E and 27°38'29.26"S 31°59'11.83"E respectively.
