With demand for water expected to increase in the approaching summer months, the Delhi Jal Board (DJB) Tuesday announced its plans to install ammonia treatment plants in water treatment plants (WTPs) to prevent their shutdown due to high levels of the chemical in raw water supply.
While presenting the Board’s ‘summer action plan’, DJB Chairperson Kapil Mishra said ammonia treatment plants ha been installed in Wazirabad and Chandrawal WTPs. Earlier this year, water supply in the capital had been affected after these plants were closed. High levels of ammonia reacts with the chlorine used to treat raw water and leads to the formation of Trihalomethane, a compound considered to be carcinogenic.
To meet the increasing demand, Mishra said two WTPs have started producing more water. Lauding the department for consistently supplying 900 million gallons daily (MGD), Mishra said all colonies will receive piped water supply by 2017. The statement, however, came with a rider. “It will depend on clearance by the urban development department and ministry,” he said.
“The Dwarka plant will be producing 40 MGD and Bawana will be producing 14 to15 MGD,” added Mishra.
In areas where there is no pipeline network, water will be supplied by nearly 700 tankers, he said.
“We have procured 250 new water tankers, apart from the 407 tankers we already have… after holding consultations with MLAs, 25,000 water points have been identified. The schedule of these tankers is available on the website along with additional information like trip diversions… distance covered etc. Last year, these tankers made 5,920 trips per day. This summer, we have a target of 6,400 trips per day. We have established a control room and we will monitor these tankers online,” said Mishra.
Speaking on the “achievements” of the department, the minister said, “We have installed 12 new tubewells at Palla which will increase raw water supply from 20 MGD to 35 MGD. We have also set up 60 new tubewells in various locations”.
He said the Delhi government will set up ‘e-piaos’ (drinking water kiosks) by May 10 and double that number in 10 days. The government plans to set up 100 such kiosks, said Mishra.
The DJB also claimed to have mapped areas ‘vulnerable’ to water deficiency and contamination, for effective monitoring.
