New special grade water treatment plant in Perungudi to supply water for construction sector

Rs 57 lakh plant to be ready by November

Chennai:

In a bid to conserve the ground water resources which is being tapped
by the construction sector, Chennai Metro Water is planning to
construct a special grade water treatment plant in Perungudi to supply
water for construction activities.

A Metro Water spokesman said that the new plant, built at a cost of Rs
56.6 lakh, would produce six lakh litres of special grade per day for
construction purposes and is likely to be commissioned on November.

Metro water will be charging Rs 20 per kilo litre for supply of
special construction grade water at the filling point and
transportation will have to be arranged by the consumers, the
spokesman said.

Interestingly, the scheme was being worked out to protect the ground
water resources. On an average the city requires 20 lakh litres of
water for construction purposes, the spokesman said.

He said the aim of the plant is to cater to the requirements of IT
corridor, where construction activities are in progress for promoting
educational institutions, IT parks, multi-storied buildings,
residential apartments and commercial establishments. It is believed
the requirements of major construction sites in IT corridor is six
lakh litres of water per day, the spokesman said.

Currently, the construction sector is relying on ground water which is
not meeting the required quality specification. This is also resulting
in the depletion of ground water table. This has resulted in the state
government working out alternate source of water which meets the
quality norms for use in concrete industry, the spokesman said.

This will ensure supply of water for construction purpose irrespective
of monsoon failure besides save the amount of fresh water that is
being tapped from lakes, borewells and rainfed lakes.

The spokesman said that the revenue realized from the waste water will
be used to meet the expenditure towards treatment of waste water.

Currently, 100 MLD of secondary treated water is available at
Perungudi sewage treatment plant and the water is being used for
gardening purposes by Chennai corporation and Tamil nadu road
Development Corporation.  Though this water is water is suitable for
construction purpose, Metro water is constructing the additional
treatment plant to treat secondary treated water so as to achieve the
required quality for production of concrete but also safe handling of
water.
