WITH 212 IT units in Hinjewadi using 13 MLD water and over 2,000 units in Pimpri-Chinchwad using nearly 100 MLD water, the Maharashtra government is mulling mandatory recycling of water for these units in a bid to curb wastage of water.

Senior officials from the Maharashtra Industrial Development Corporation (MIDC) have said that it is high time that the state government initiates quick action to take care of the looming water crisis.

Industries minister Subhash Desai had instructed authorities to study the feasibility of raising the height of dams, desilting and deepening of lakes under its jurisdiction as part of its watershed management plan and bringing a law which will make it mandatory for industries to use recycled water.

“The change in laws, which will make some rules mandatory, will bring down the consumption that will bring about a whole new approach of usage of water for industries,’’ said senior officials from MIDC in Pune district.

In Pune district, the MIDC authorities said while in the Hinjewadi area, they normally lift about 24 MLD water from the river for water treatment, they have been lifting only 13 MLD this year due to water crisis and while some units have their own recycling plants, the MIDC has a 4 MLD capacity Sewage Treatment Plant that treats water released, which in turn is used for gardening of plants.

In the Hinjewadi area, there are 91 units in Phase 1 sector, followed by 40 in Phase 2 and 81 in Phase 3, of which 151 units are in operation. “While the rules are mandatory for a zero discharge, most of them do their own treatment of water,” said the official.

In the PCMC area, with the 2,000 additional units in the area, the requirement is about 100 MLD. “The goverment’s initiative to ensure compulsory recycling of water will definitely ensure that there is no wastage,’’ said a senior official who handles water distribution in the area.

On the same lines, Pune environment experts had even demanded for a revision of the industry policy on rainwater harvesting. While rainwater harvesting is allowed, they continue to use water from the Maharashtra Industrial Development Corporation. Experts have called upon a change in this policy as these industries are calling for tanker water services from MIDC instead of using the harvested water. According to statistics, the MIDC has about 233 industrial complexes spread over 1,30,000 acres of land all over the state.

Rainwater harvesting expert Col SG Dalvi, from the climate reality project, said that even as the industry is permitted to have rainwater harvesting system, it was not allowed to use the harvested rain water, making it a lame policy.
