Very pertinent point, Sir, in several states of US, harnessing rainwater has been banned just because that rainwater is needed to be infiltrated into everybody's land so that it can emerge in some water body or other by natural distribution. While we are fighting for the right to the scarce quantum of ground water and the scant little in our river systems, it is ironical that rainwater harvesting is still being relegated as one of the obligations the property developer must address, nothing more. Creation of underground buffers at shallow depths for reuse later, can provide an answer to the undue stress we are creating on our water bodies. Communities can hold rainwater under sand bed filters in much cleaner state using Geocellular blocks lined with HDPE to make such tanks with humongous capacity. Shallow storage under engineered soil beds shall allow the rainwater to stay sterile, devoid of the contaminants like Arsenic, Cadmium, Chromates etc that have actually made most of our ground water in the water stressed areas unfit for human consumption. Unlike surface storage in ponds, rainwater harvested in such underground private aquifers shall also stay protected from evaporation losses, dust contamination and algae/ invasive plant infestation.
