Usually the corporation would start gradually reducing the duration of water supply and quantity from mid-February in order to maintain minimum distribution till the onset of southwest monsoon by first week of June.

Because the water level in Siruvani dam, the major water source to the city and certain roadside panchayats, would start dipping slowly from February.

The civic body would also advise the residents to use water judiciously during peak summer.

This year, Tamil Nadu Water and Drainage Maintenance (TWAD) Board, which is maintaining the Siruvani dam and supplying water to the corporation for distribution on payment, has taken precautionary measures one month in advance by reducing 10 per cent water release to ensure steady supply till arrival of summer rains/SW monsoon.

The State government had asked the TWAD Board to take special care of water supply in Coimbatore advising that there would not be complaints from the residents against erratic water supply/much reduction in quantity.

P Gopalakrishnan, Executive Engineer, TWAD Board, incharge of Siruvani dam, told Express: “It is natural that the dam level will decrease inch by inch on daily basis during non-rain season (from February to May).

The TWAD Board will start reducing the supply to the corporation either by mid- February or March and there may be severe cut in supply during peak summer months-April and May depending upon the situation.”
