Kolkata, Sep 27 (UNI) Keeping in view the loss of rain water, the West Bengal government has made it mandatory for all the new constructions to have rain water harvesting (RWH) equipment.

Addressing a workshop ''Rainwater Harvesting and Water Treatment Technologies,'' Environment Minister Sailen Sarkar said several areas in the state, including Kolkata, were facing acute shortage of drinking water despite recieving an annual rainfall of more than 1300 mm.

''Each and every house should have RWH measures like Recharge pit, trench, shaft and well, besides percolation tank to tap this natural resource,''he added.

This would also help in elevating the receeding ground water level, the minister said.

Speaking on the occasion, UN-Habitat Cheif Technical Advisor Dr Kulwant Singh said the organisation, with the approval of Kolkata Municipal Corporation, would start a RWH project involving schools in the state for the first time.

He said about 150 government and private schools have been identified in Kolkata and its adjoining areas, where the rain water would be stored.

The 200,000 US dollar project would start by the year end with Coco Cola as partner, Dr Singh said.

He further said the UN-Habitat have started Water for Asian Cities programmes in Nepal, Vietnam and Cambodia. In India it was started in 2003 and this year the project would begin in Indonesia.

By 2025, India's total water demand will be about 91 per cent of the total available water, Mr Singh said.

''This is alarming as the country's total water resource of 1150 cubic km per year is not being uniformly distributed,'' Dr Singh reiterated.
