With a water supply crisis imminent in Gurgaon, Gurugram Metropolitan Development Authority (GMDA) has asked power discom Dakshin Haryana Bijli Vitran Nigam to urgently look into the problem of frequent power tripping at the city’s two water treatment plants at Basai and Chandu Budhera.
The GMDA has compiled a detailed tripping report of the past three months — from April to June. The two plants are equipped with more than 50 motors. In the event of tripping, the motors come to a sudden halt.
“This problem has risen to thrice daily over the last 90 days. On days, there are as many as 7 to 8 tripping incidents at the two plants. It has emerged as a big concern for us, as it not only threatens to damage the infrastructure that we have put in place here but also affect supply significantly,” explained a senior GMDA engineer, who didn’t want to be named.
He continued, “When the feeder lines trip, they result in backflow of the water that it supplied through our pipelines. When the power is restored, we cannot start all our motors at one go. They are restarted one after the other for safety reasons. Often, the feeder lines trip just when we are in the process of restarting the motors. As per the report that we have compiled, there have been as many as 150 tripping incidents at our two treatment plants and two boosting stations, at sectors 16 and 51, in the last 90 days. This report was presented at a high-level meeting of GMDA officials. Some residents at nearby villages have even resorted to taking illegal connections from our dedicated feeder lines.”
GMDA officials said pipelines often burst when they restart motors to keep supply in flow after tripping.
Lalit Arora, superintending engineer, Wet Infra, GMDA, said, “We held talks with the DHBVN in this regard and are trying our best to resolve the issue. The supply has improved over the last couple of days. We are trying to augment our electricity infrastructure at the plants as well.”
According to estimates, 150 trippings affected supply of over 100 MGD in the last three months and resulted in several pipeline bursts.
The DHBVN officials have denied any fault in the feeder lines to the two plants and attributed the frequent tripping to squalls and rainfall over the last three months.
Sanjiv Chopra, chief engineer, DHBVN, explained, “We only supply electricity to the external points of these plants. GMDA has its own internal distribution system. So, this tripping is not due to a deficiency in supply at our end.”TAGS: DHBVN / GMDA / deficiency in supply / tripping / Dakshin Haryana Bijli Vitran Nigam / Basai and Chandu Budhera / Pipe bursts
