To sail through water crisis in the city the civic body is looking for several options, one of them is setting up of water filters throughout the city.
Now that the civic corporation will make use of well water for this, the Brihanmumbai Municipal Corporation will set up water filters in different wards so that ground water from borewells and dugwells can be filtered and used.
Currently, the water stock in the six lakes that supply water to the city is 9 lakh million litres. At the same time last year, the stock was 13.2 lakh million litres.
The city is already facing a 15 per cent water cuts, which the civic body could increase t0 25 per cent.
“We have already started cleaning and repairing of different types of wells in the city. Once they are cleaned, we will connect them to these filters,” said Additional Municipal Commissioner Anil Diggikar.
An amount of Rs 48 crore has been provisioned for repair of borewells in the city.
So what exactly will these water filters do?
They will be akin to large-scale Aquaguard units that will filter impurities and dirt from water extracted from wells, said Diggikar. Each filter is expected to have a holding capacity of 4,000 to 5,000 litres.
“The filters will largely benefit areas located at a height where water supply is reduced to a trickle due to low pressure,” Diggikar said. Like Malabar Hill, Wadala and Powai, for instance.
“There is a chance that some wells may have more than one filter plant connected, depending on the capacity of the well,” said Diggikar.
Besides, the filtration plants, setting up of desalination plants and sewage treatment plants is also on the cards as a long-term measure to provide water for non-potable use. “The overall cost for such plants will be between Rs 2 and Rs 5 lakh,” said Diggikar.
He said these plants would be set up as soon as the repairs to the wells are completed.
