CAPpings - India - Water Distribution - Loss of around 1.5 lakh litres of water daily through pipeline leaks leading to drinking water shortage in Kochi, Kerala

Loss of around 1.5 lakh litres of water daily through pipeline leaks. With the per capita requirement fixed by KWA at 150 litres, the loss of 1.5 lakh litres means that around 1,000 consumers are deprived of water due to the said leaks alone


KOCHI: After a long wait, the Kerala Water Authority (KWA) has started using SmartBall and Sahara technologies to detect leaks in the supply network. Initially, they have started inspecting the 42-inch pipeline, one among the three main pipelines that supply water to the city from KWA's treatment plant at Aluva, using the SmartBall technology.

When they completed a 5km stretch of the around 20km-long pipeline, three leaks were detected last week. Each leak results in a loss of 35 litres per minute. This translates into a loss of around 1.5 lakh litres of water daily through these leaks. With the per capita requirement fixed by KWA at 150 litres, the loss of 1.5 lakh litres means that around 1,000 consumers are deprived of water due to the said leaks alone.

Many parts of Kochi such as Fort Kochi, Mattancherry, Thevara, Cheranelloor and Vypeen islands are facing drinking water shortage even though the monsoon has not departed yet. "In Soorya Nagar, Maydina and Thevara colonies, residents went up in arms after they were made to wait for days for drinking water supply. The KWA would always cite one or the other reason for supply shortage," said Thevara division councilor Ranish P R.

In Fort Kochi and Mattancherry areas, chikungunya has become a major cause of worry after health officials found that water stored by local residents in vessels without covers had turned into breeding grounds for mosquitoes. The residents of west Kochi are forced to store water as the same is in short supply. The KWA will continue to conduct checks using SmartBall and Sahara technologies in the coming days. "We have found that water generated from our Aluva plant is not reaching many parts of Kochi. But we were not able to detect how water is lost in between. That's why we decided to introduce SmartBall and Sahara technologies," said KWA chief engineer A K Ramani.

According to KWA officials, they have always taken steps to plug leaks whenever such cases are reported to them. "There are problems in detecting leaks. There is a control room functioning round-the-clock to address complaints regarding leaks and pipe bursts. Once a problem is reported, we would soon deploy our maintenance contractors for repair works," insisted KWA superintending engineer Jolly Thomas.

  1. Loss of 1.5 lakh litres of water per day is an alarming level. Leak detection through advanced monitoring technique is one way to spot the leak spots for further maintenance. But this is not the only solution to reduce water losses. Considering the profound loss, the day to day monitoring of water supplied to the public needs to be stepped up and detect the parameters responsible for generating leak spots. There is no specific focus on corrosion control applied for the aged pipeline network. Water management authorities have to find a suitable corrosion management and maintenance program for these old assets and take immediate solutions for minimizing the leak rate and contamination threats.
