oa Civil Engineering = Siviele Ingenieurswese - Innovative approach to treating variable water quality in North West
The Mmabatho Waterworks had to accommodate a relatively high proportion of treated sewage inflow and the pollutants washed from the town directly into the dam The Mafikeng-Mmabatho conurbation has been served with dolomitic water from the Molopo Eye for countless decades. As the demand increased beyond the surface outflow from the eye, boreholes were sunk into another aquifer, the Grootfontein compartment. At the same time, local farmers have been tapping these sources for irrigation water, significantly increasing the total withdrawal, resulting in over-utilisation.
