Emergency programmes under way to assist municipalities — Creamer Media’s Engineering News
Engineering and environmental consultants SSI has devised a number of emergency projects to assist the municipalities of the southern Cape coastal belt, in light of the severe drought that the area is experiencing.
SSI communications manager Robin Hayes says that during December, tourists flood the region, swelling the resident population by up to five times, exacerbating the existing critical shortage of water.
SSI water sector head Francis Gibbons says that, in Sedgefield, the company specified a 1Ml/day mobile desalination reverse-osmosis plant, together with an upgraded membrane bioreactor wastewater treatment works (WWTW) that enables the indirect reuse of final effluent. New boreholes have also been installed to augment ground and surface water supplies.
SSI’s medium term solution for Knysna and George also involves indirect effluent reuse, where final WWTW effluent is polished by an ultrafiltration process and then pumped into the towns’ storage dams where it combines with fresh water from the rivers.
