The Table Mountain Group Aquifers (TMGA) have the potential to develop a large scale scheme to augment the City of Cape Town’s water supply on a more permanent basis, mayor Patricia de Lille said on Sunday. De Lille on Sunday visited the site of a pilot project for the abstraction of water from the TMGA at the Steenbras catchment area near Somersel West. The Table Mountain Group (TMG) is a deep-lying group of rock formations or layers that extends from Van Rynsdorp to Cape Town and from Cape Town to Port Elizabeth. “The TMG aquifers have the potential to develop a large scale scheme to augment the city’s water supply on a more permanent basis,” De Lille said. The city was currently drilling test abstraction boreholes in the Steenbras catchment area, which would inform the design of a full-scale well-field and support a water use licence application for full-scale production.
