TWAD to soon take up Pilloor Phase I diversion project
The Tamil Nadu Water Supply and Drainage (TWAD) Board will soon implement a project to divert the Pilloor Phase I project water to Palladam Municipality, 23 town panchayats and 965 wayside habitations.
It will start the project once the Coimbatore Corporation makes the Pilloor Phase II drinking water scheme operational and brings to naught its dependence on the Phase I scheme water. Sources said the TWAD Board was implementing the project at Rs. 224 crore to replace the water supply main pipeline with bigger ones, change, wherever necessary, distribution supply network and build overhead tanks. It was necessary to increase the capacity of the supply mains up to 1,020 mm because the Board would increase the water supply from 65 to 125 million litres a day (mld).
The replacement, repair and refurbishment of the Pilloor Phase I scheme would involve digging for around 600 km to lay pipelines, including nearly 50 km for the main supply line and construction of 102 overhead tanks, including 77 in urban areas.
The sources said the Board would construct the tanks to replace the existing ones with tanks of bigger capacity.
The Board would use pipes made out of mild steel or ductile iron for main lines and those made of polyvinylchloride in distribution networks.
The sources further said the work would be completed by either the end of 2013 or early 2014. At present, the Board was scrutinising the bids submitted by five persons. The Coimbatore Corporation now gets the 65 mld to meet the drinking water needs of residents in East and South Zones. It is implementing Pilloor Phase II scheme, under the Jawaharlal Nehru Urban Renewal Mission project, to provide around 125 mld.
