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.
