The amount is limited to 50 percent of the allocation for the first and second quarters to HMWS&SB in 2009-2010 for improvement of water supply in the city’s slum areas under Plan Scheme.

The HMWS&SB should utilise the funds as per the allocation of the works and furnish the expenditure particulars and utilisation certificate to the State Government on monthly basis.

The dirty and contaminated water would be purified in these models and the purity of the so purified water would be displayed to the visitors at the park.

The technology involved in purifying the water would also be explained to the visitors.

This measure is expected to clear the misconceptions about the use of filtered and treated water for various purposes. One of the BWSSB officials said, ``this is the first step to educate the people about the harmlessness of using the treated water for various purposes. All the water sources to the city would be exhausted very soon. Purified and treated sewage is seen as the one of the possible future sources of drinking water to the city.’’ According to the projections, the city would need nearly 2,550 MLD of water by 2040 and even if all the existing sources of water is exploited only1,500 MLD of water can be supplied to the city by then. There are practical and financial constraints in bringing distant water to the city. Treated sewage can meet the water requirements of the city, as more than 70 per cent of the water supplied is discharged as sewage.

It may be recalled that the BWSSB had to postpone its project to supply the purified and treated sewage for drinking purposes due to strong public disfavor. At present, the BWSSB is planning to supply the water that is treated in its sewage treatment plants for washing purposes through separate pipelines that would be laid for that purpose.
