BASIC ASSESSMENT PROCESS FOR THE PROPOSED CONSTRUCTION OF AN OXIDATION POND SYSTEM AND TWO GRAVITY OUTFALL SEWER LINES NEAR SCHWEIZER-RENEKE, NORTH WEST PROVINCE.

Moedi Consulting Engineers proposes to construct an oxidation pond system and two gravity outfall sewer lines near Schweizer-Reneke, North West Province. The configuration of the existing sewer system entails that all wastewater generated in Ipelegeng gravitates to five (5) pumping stations. The current pumping system installed on site is not sufficient to convey wastewater to the Waste Water Treatment Plant (WWTP) and this results in spillages occurring due to the overloading of infrastructure. The motivation for the proposed project is twofold. Firstly, it will address the current capacity shortfall by reducing the inflow volume at pumping stations, and secondly, it will optimise the current sewer network to operate more efficiently by decreasing the pumping and repumping of sewage. It is proposed that two “cut-off” gravity outfall lines be installed to reduce the load on the pumping stations and furthermore, it is proposed that an oxidation pond be constructed to decommission Pumping Station A.
