NMMC will make Rs 494 cr in 15 years, MIDC to save precious drinking water

NAVI MUMBAI, Oct 18 (The CONNECT) - Perhaps for the first time in the country, 40 MLD (million-litres a day) of urban recycled sewer water and treated with ultra-filtration and ultra-violet technology will be supplied for industrial use in Navi Mumbai, thus saving precious drinking water.

Environment-focused NatConnect Foundation has suggested to the Government and the civic body to save drinking water by supplying the recycled water for industrial and non-potable uses. NatConnect has also suggested a one-time investment in a separate pipeline and storage facilities for this purpose.

Navi Mumbai Municipal Corporation will supply the recycled water to the units in the estate run by the Maharashtra Industrial Development Corporation (MIDC) at Rs 18 per cubic metre.

For the uninitiated, the MIDC has been supplying the same drinking water drawn from the Barvi dam to industrial as well as residential areas. For long, Navi Mumbai has been buying MIDC water until the City got own dam at Morbe in 2002. The dam was built by Water Supply and Sanitation Department of the Government of Maharashtra which transferred the project to NMMC.

NMMC administers part of the planned city that falls under Thane district, while the rest of the area is under Raigad district and is still largely managed by CIDCO.

NMMC area generates 450 MLD of sewer water and the civic body built seven treatment plants to recycle 100% scientifically, a civic body spokesperson said.

Additionally, NMMC built two tertiary treatment plants with the capacity to handle 20 MLD each with ultra -filtration and ultra-violet facility at Kopar Khairane and Airoli respectively. The civic body will start supplying this quantity to MIDC units within three months.

NMMC will earn about Rs 494 crores in 15 years, while MIDC will be able to save 40 MLD of drinking water which it can supply to other urban areas.

The quality of the treated water at the two stations is above the benchmarks set by the central as well as the state pollution control boards, NMMC claimed.

The trend-setter plants have been commissioned under AMRUT (Atal Mission for Rejuvenation and Urban Transformation) which is reincarnation of JNNRUM (Jawaharlal Nehru National Urban Renewal Mission) of the Congress regime.
