The 'no power' shit hit the fan, 20-Mill to make a plan

The City of Cape Town is looking to spend up to R20-million urgently on back-up generators to prevent sewage spills from pump-stations during power failures. The city has 393 pump stations that fail when their power supply is cut.

Normally the sewage is pumped from these stations to a waste-water treatment plant. Because they are gravity fed from residential areas, sewage continues to flow into the pump stations even when their pumps are off.

When they are full, overflow sewage is diverted into the stormwater system, which feeds into rivers, wetlands and vleis, so that it does not spill into and contaminate residential areas. Full Story
