Chennai Metrowater will soon be implementing a Rs 245.55 crore sewerage scheme in Kathivakkam, Sholinganallur, Karapakkam and Ramapuram under the Chennai Mega City Development Mission.
A Metro Water spokesman said that work orders had been issued for Kahthivakkam, Sholinganallur and Karapakkam. The work will be taken up shortly at a total cost of `162.33 crore. In the case of Ramapuram, tenders are under evaluation and the work orders are likely to be issued soon, he said and added that more than 46,280 houses were likely to benefit from the sewerage schemes, the spokesman said.
He said that in Kathivakkam, the plan is to build an underground sewerage network. “The area currently has no sewerage system and most of the households are dependent on septic tanks or holding tanks. The sewage water from some houses are directly let into open roadside drains that find their way to the nearest low lying areas,” he said.
Similarly in Sholinganallur and Karapakkam, the plan is to have 3,557 manholes besides construction of 10 sewage pumping stations and providing cast iron pumping main of a length of 12,350 metres.
In Ramapuram where there is no sewerage system, Metro water plans to build a comprehensive underground sewerage scheme for the entire area to stop houses letting out the sewage to roadside drains. “We will be providing collection system with Stoneware pipes and cast iron pipes for a length of 49,104 metres with 1,927 manholes. The plan is also to build five sewage pumping stations,” the Metro Water spokesman said.
The sewerage schemes in the four areas will improve the hygienic and sanitary conditions in the area, the spokesman said.
He said that it will take 30 months to finish the schemes in the four areas and this would benefit a population of 1.26 lakh people, the spokesman added.
