Kouga's search for extra groundwater to increase the water supply to towns is bearing fruit.
Almost 30 exploratory boreholes have been sunk over the past year at Jeffreys Bay, Humansdorp, Oyster Bay, Hankey and Patensie.
"Of the 26 target sites that have already been explored, 18 delivered water, although not always in quantities that make it viable as an alternative supply," Kouga Executive Mayor Horatio Hendricks said.
Eight exploratory boreholes have been drilled in the vicinity of Hankey, with three delivering yields.
Two probe holes and two boreholes, delivering a combined total of 820kl per day, were drilled at Humansdorp during the previous financial year. A third borehole was completed last week, with drilling at another potential site currently in progress.
