Mossel Bay now has plenty of water

In October 2010 the level of the Wolwedans Dam, the main source of water for the Mossel Bay Municipality, was down to just 14,5 per cent. This week the dam’s level rose to over 101 per cent following more good rain in the dam’s catchment area since last Friday (22 July 2011). The other dams from which the Municipality draws water are also flowing over.




The Wolwedans Dam flowed over for the first time again following the heavy rains in June 2011. Another 69 mm of rain was measured at the Municipality’s sewerage plant at Hartenbos and 43,9 mm at the Sandhoogte sewerage plant nearGreatBrakRiversince last Friday.




On Tuesday, 26 July 2011, the Wolwedans Dam’s level stood at 101,52 per cent, and that of the Ernst Robertson Dam at 101,72 per cent. The Hartebeeskuil Dam stood at 107,91 per cent and Klipheuwel Dam at 107 per cent.




“This means thatMosselBayhas sufficient water to meet the demand for nearly two years if it does not rain again. We are therefore in very good position right now.




“However, while the new water sources, such as the seawater desalination plant which the Municipality developed, now seems to be superfluous, it must be remembered thatMosselBayperiodically suffers severe droughts. Its population has also nearly doubled from twenty years ago and it can be taken for granted that there will again be times that the Municipality will have to rely on these others sources instead of the dams,” said the Municipal Manager, dr Michele Gratz.




Apart from the seawater desalination plant, the Municipality also sunk several boreholes and built a plant to reclaim waste water for industrial purposes. These projects were also carried out at the request of the Department of Water Affairs to reduce the Municipality’s reliance on surface water. The Municipality considered building a seawater desalination plant in 2014 but brought this forward because of the recent drought.
