Chandigarh:The UT Administration has stopped the inflow of drinking water being drawn from seven tubewells into the Sukhna Lake. The water inflow has been stopped citing the drinking water requirement in the city, said UT Chief Engineer Mukesh Anand.
The drinking water from seven tubewells was drawn to feed the Sukhna Lake after the High Court’s intervention of saving rgw lake from drying.
The UT Administration has pumped in 1.5 million gallons of drinking water per Day (mgd), hoping to raise the water level in the Sukhna Lake by about 5 inches every month. There has been no rise in the water table but the UT has wasted Rs 45 lakh public money.
According to the daily monitoring committee of the UT Environment Department, the day-to-day water level observed at the Sukhna Lake and according to the report generated the water table in maintained between 1154.35 feet and 1154.40 feet.
The drinking water input into Sukhna Lake has only maintained the evaporation level in past two months.
UT Environment Department Director Santosh Kumar said, “As per the study report of the National Institute of Hydrology, Roorkee, the 1.5 mgd of water fed into lake monthly is equivalent to the evaporation rate of 4 mm on daily basis. According to the calculations, the water from tubewells fed into the lake is 4 mm per day, hence the water fed is equal to the water evaporated on daily basis.”
According to the interim study report by the National Institute of Hydrology, Roorkee, the water evaporation rate in the Sukhna Lake is 4 mm per day in the months of November, December, January and February. This will rise to 10 mm in March and in April, May and June the evaporation rate rises to 15 mm per day.
The Chandigarh administration had earlier informed the court that around 1.5 million gallons per day (mgd) would be pumped into the lake from seven tubewells since January and an estimated 6-7 inches increase in water level is expected over a month.
