Narmada-III water to be supplied via HDPE

THE DAYS of water supply disruption and contamination caused by leaky pipes may soon draw to an end. The Project Monitoring Group for ADB-assisted Urban Water Supply and Environment Improvement Project (USWEIP) is mulling over a proposal to use High Density Polyethylene Pipes (HDPE) for supplying water under phase three of the Narmada project.

THE DAYS of water supply disruption and contamination caused by leaky pipes may soon draw to an end. The Project Monitoring Group for ADB-assisted Urban Water Supply and Environment Improvement Project (USWEIP) is mulling over a proposal to use High Density Polyethylene Pipes (HDPE) for supplying water under phase three of the Narmada project.

The HDPE pipes offer innumerable advantages over their asbestos and iron counterparts, as they are corrosion resistant and excellent in water hammer characteristics. Furthermore, the pipes are normally joined by heat fusion at a distance of every 100 feet making them virtually leak free.

A factor that is expected to reduce maintenance costs considerably as leak detection and rectification currently takes up a lot of the Narmada official’s time and budget. Besides, the excellent flow rate in the HDPE pipe can maintain good volumetric flow rate at high pressure.

According to PHE sources engineers from the four ADB beneficiary cities - Indore, Bhopal, Jabalpur and Gwalior- recently visited Nasik, Vadodara and other cities to gauge the utility of HDPE pipes.  Although, the ADB Project Monitoring Unit (PMU) has yet not finalised the type of pipe to be used advantages over iron, asbestos and cement pipes may lead the unit to vote in favour of HDPE.

While admitting that offers had been received from various pipe manufacturers Project Director of ADB Project Gulshan Bamra said approval hinged on getting a nod from the ADB.
