Replacement of AC secondary water mains Ethekwini Municipality has embarked on a project to replace the old Asbestos Cement (AC) secondary water reticulation mains within the metropolitan municipal area. This project will decrease the huge costs incurred due to the high frequency of burst pipes that causes damage to roads, properties and pavements. High water losses associated with pipe bursts and leaks will also be reduced. S BA has been appointed for the design and construction monitoring for the northern area of Durban, which extends from the Umgeni River to the Tongaat River and inland from the coast to Inanda and Phoenix. The project entails the replacement of the old un-dipped bitumen AC mains with new mPVC mains, including re-connection of the existing consumer connections to the new mains and the installation of new isolating valves and fire hydrants. The scope of work also includes hydraulic analysis of the networks to determine the optimum size of replacement pipes and pressure zoning that will reduce high pressure in these networks.
