Since the southwest monsoon set in over Pune district, the catchment areas of four dams supplying drinking water to Pune has received heavy rainfall for the first time in the season on Thursday and Friday, taking the water stock up to 32.14 per cent.

PUNE: Since the southwest monsoon set in over Pune district, the catchment areas of four dams supplying drinking water to Pune has received heavy rainfall for the first time in the season on Thursday and Friday, taking the water stock up to 32.14 per cent. The mere 36 hour rainfall in the catchment areas of Khadakwasla, Panshet, Varasgaon and Temghar resulted in the inflow of total 1.31 thousand million cubic (TMC) feet in the four dams.

According to the Maharashtra Water Resources Department, the rainfall is still continuing with intermittently heavy showers. With the heavy rainfall, the water stock in all the four dams swelled up to 32.14 per cent. By 8 am on Friday, the total water stock in Khadakwasla division was 9.37 TMC. However, last year on the same day, the water stock in the four dams was 13.75 TMC, which was almost more by 4.38 TMC and the dams were filled up to 47.14 per cent. Interestingly, till recently, Temghar and Varasgaon dams had zero per cent water stock, but now both the dams have 0.40 TMC and 3.13 TMC water stock respectively.

As per data released by the State water resources department, during last 36 hours, Khadakwasla dam received total 27 mm rainfall, Panshet 74 mm, Varasgaon total 80 mm and Temghar 111 mm and from June 1, the total rainfall occurred in the catchment areas of all the four dams is 2,681 mm against the average rainfall of around 7,000 mm. Although the rainfall occurred on Thursday and Friday, the inflow of water will keep gathering in the dams for the next few days.

The State water resources department planned the use of available water in the dams for providing drinking water to Pune in such a way that the water stock will last till mid-August, but with increased water stock in all the four dams and still more than two-and-a-half month of monsoon yet to go, the present water stock would last for three more months.

Everyday, the PMC lifts 1,250 MLD water to supply the population of more than 35 lakh and for supplying water for the entire year, the water supply department of the PMC needs around 14 TMC water, which is almost half storage capacity of the four dams.
