The City said in a new report released at the beginning of this year that the aquifer water from the Cape Flats Aquifer, which is located in the Philippi Horticultural Area (PHA), “is not suitable for immediate human consumption and must be treated to potable standards before it enters the reticulation system”.
“The issue that we have raised with the City regarding the aquifers is that if you extract water then you must be able to maintain the water and it’s clear that the City has no clear plan in place,” said Delmaine Cottee, ANC councillor and member of the City’s water and sanitation portfolio committee.
According to the City’s report, it was hoped that potable water could be pumped out of the aquifer by last September, but this was reassessed after good autumn rainfall and estimates of the cost of treating the water before piping it into the drinking water system. The boreholes producing the highest yields are the most polluted.
To date, no water from the aquifer has been used to augment the supply of drinking water.
