The preparation of the draft regulation, a detailed database that will comprise the information on the households receiving filtered water supply from the KMC, is still under way.

"The work on the draft regulation has just started. It will take another three months to prepare the entire list of households receiving the KMC supply," said a senior official of the KMC's Water Supply Department.

Following the Mmic's approval, the water tax proposal was passed in the civic body's budget session on March 15. While 20 Congress councillors and 42 TMC councillors had opposed the proposal, the majority of 72 Left Front councillors had voted in the favour of the proposal. After its passage in the budget, the proposal was to be forwarded to the urban planning department. The water tax can be implemented in the city only after the department gives it a clearance.

At present, the KMC supplies water to 2,68,000 households in Kolkata. On an average, the water being supplied from the 19 KMCrun boosting stations and water treatment plants is around 270 million gallons.

However, to serve a population of 45 lakh, the city needs a supply of 300 million gallons of water per day.
