There is some good news. According to officials from the civic hydraulic department, the Powai lake overflowed at 8.15 pm on Monday.
While the lake does not supply drinking water to Mumbai, it caters to non-potable supplies to industrial units at Aarey Colony and Powai.
Hydraulic department officials said the lake supplies 10 million litres of water to units operating from the Aarey Milk Colony area in Goregoan. It also supplies 1 million litres to the Larsen and Toubro unit at Powai.
Healthy rains during the weekend over reservoirs supplying water to the city also led to a sizeable increase in the water level in these catchments. Officials from the civic hydraulic department said the collective water available in these belts had risen by 11,399 million litres during the weekend. At current supply standards, the added quantity can quench city’s thirst for four days.
Additional municipal commissioner Anil Diggikar welcomed the development. He, however, reiterated that there was still a long way before the water cuts imposed on the city could be lifted. “The catchments presently hold 1.4lakh million litres of water. The comfort margin will be attained when the same touches 8-9 lakh million litres,” Diggikar said.
Hydraulic engineer Vinay Deshpande said the rainfall in the catchments continued to be below par compared to the average witnessed during fair monsoon month in the recent times. The average water content available around this time between 2006 and 2008 was 4.20lakh million litres.
The Vihar reservoir has so far seen the most amount of rainfall. It has witnessed 1,180 mm rainfall, while the Tulsi reservoir has seen the second highest rainfall at 614 mm.
