Residents of Gurgaon might face water shortage over the next two days as the Haryana Urban Development Authority (Huda) will reduce supply after the district’s water canal recently developed a breach.
On Monday night, walls of the 71-km Gurgaon Water Supply Canal (GWSC) collapsed and hundreds of acres of adjoining agricultural land were submerged.
Although the 50-m breach near Bhadsa village was temporarily repaired on Wednesday morning, Huda and irrigation department officials have partially restored water supply. Huda has decided to reduce water supply to New Gurgaon and parts of Old Gurgaon from 70 million gallons per day (mgd) to 60mgd.
Additionally, it has been releasing water in phases to ensure the mended portion does not collapse again.
“Only three pumps are being used to release water instead of the usual five. The walls might collapse if there is lot of pressure on the canal,” Subash Piplani, sub-divisional engineer of Huda’s division 3, said.
To ensure the crisis is not severe, Huda will supply water from its buffer stock in the Basai water treatment plant. The development authority will use its 280mgd water that covers the demand for about four days. As backup, Huda will supply 5mgd water from its plant at Chandu Budhera.
“There are chances of not getting supply from the canal at all,” Piplani said.
Gurgaon consumes 82mgd water every day, of which 70mgd comes from the GWSC. The canal, which originates from Kakroi village near Sonipat, has a capacity of 175 cusecs. However, half of the water is lost to evaporation and leakages, a report released by the Centre for Science and Environment (CSE) in 2012 stated.
The canal has been in a poor condition for long, which is also why only 40% of the supply reaches the Basai plant. From here, Huda supplies water across Gurgaon in three zones — zones 1 and 2 comprise Sectors 1-44 and Old Gurgaon, while zone 3 comprises Sectors 45-54 and Sohna Road. Zones 1 and 2 get about 60mgd from the Basai treatment plant and nearly 10mgd is supplied from the Chandu Budhera plant to zone 3.
Piplani said the irrigation department has drafted a proposal for repairing the canal and has sent it to the headquarters in Chandigarh for approval.
Meanwhile, Huda administrator Anshaj Singh visited the Basai treatment plant and also the engineering wing to clean the water tank.
He has also told officials concerned to get a wall built from the tank to the treatment unit as it was crucial to maintain hygiene.
