The Coimbatore Corporation has shown the yellow card on the water supply front. The Siruvani Reservoir has only 2.72 feet water and that will last for about 10 days at the current rate of supply of over 40 million litres a day (mld).

For the last few days, the water level in the reservoir has been coming down gradually. On June 12 the water level stood at 3.28 feet. The next day there was no change. And since then there has been a gradual decline in the level — 3.11 feet on June 14 and 2.90 feet on June 15 as the Tamil Nadu Water Supply and Drainage Board had maintained a supply of over 40 mld to the corporation.

But there has been no rain of any significance in the reservoir. Data available with the corporation reveals that on June 13 the reservoir received 10mm rain. The entry for the subsequent days at the daily register has been nought.

Sources in the corporation say that at the current level of usage, the water will last just 10 days. Once the water touches the dead storage level, the corporation will be forced to rely on Pilloor water for compensating the residents who received Siruvani water.

The corporation supplied the Siruvani water to 26 Wards in full, and another nine Wards in part. For the rest of the 100 Wards the corporation supplied Pilloor, Bhavani, and Aliyar waters.

Once the Siruvani water dry up, the corporation would supply Pilloor water. Enough pipeline linkages have been established to divert the Pilloor water to the Siruvani-fed areas, the corporation sources said and added that they had asked people to make judicious use of the available water.

The corporation faced a similar situation at this time of last year too as the Siruvani catchment areas did not receive adequate rain.
