Flood control is generally sought to be done with storm water drainage. This always is an expensive proposition, and assumes that the lay of the land is such, that the water can flow down to the lowest spot. Very rarely people seek to use the rain water to recharge the undergound source. This attempt of using rain water to recharge the underground storage is generally termed as rain water harvesing. Many think that rain water harvestin is storing the rainwater in a manually constructed storage system. this would be possible only in some cases, where the rain is scanty, and the construction of the small ponds with bund desing to store th flow of water. The underground charging is simple in many cases, but there can be no universal solution. The logic is to create a clear passage to the existing water level, or to the soil layer which can allow water to probogate laterally in the fastest manner. Thus, it is essential to study the soil layers, know the permeability of the soil at various levels. Various methods include drilling a number of bore wells, and fill them with large pebbles, use existing open wells, which go beyond the exisitng impermeable soil layer, understand the underground water flow, knowledge of the rain fall pattern and reasonable time for allowing the water to drain to the underground. In addition, proper treament of grey water to charge the undergound also ensures that the ground water availablity is assured even in the years of scanty rainfall. By ensuring that more water is charged into the underground than the annual requirement, the whole area would have no water shartage for ever. SECO offers to provide this service at a nominal cost, as a commitment to ecology and for the future of our children and grand children. Ofcourse, where the rain fall is far in excess than can be charged underground, over the land drainange channels would be essential. SECO is proud of the fact that both at its office premise and at the house of Mr.Jayaraman, no water goes outside the premises, and all the water, both used and the rainwater, goes to the underground after required treatment – without any machinary and maintanance.
