The ongoing dry weather is not the only reason that pipe borne water is salty for about 50,000 families in the Kalutara district, a Water Board official said yesterday.He said riverbed sand mining that has been going on at a rate in Kalu Ganga, Bolgoda Lake and Panadura River with or without the support of local authorities, the Grama Niladharis and others, had caused sea water to flow into the Kalu Ganga, which the Board uses to pump water from.
