Gulsher Panhwar in his letter has quite rightly advocated the use of Solar powered tube wells which will greatly benefit the farmers. The question is, how long will the groundwater last if it is not recharged by the canals which are running dry? DHA Lahore has sent an advisory to the residents not to use hose pipes for washing cars and car aprons but use water from buckets. They have informed that the water table is going down 3 to 4 feet every year. Our only two reservoirs are silting up and no reservoir has bas been built for the last 38 years and is not likely to be built for another 10 years at least if our present government keeps ignoring the writing on the wall.
