India : Water metering to be introduced in all municipal corporations

‘Supply to households, commercial units will be monitored from control rooms’

In an effort to improve the efficiency of drinking water supply and reduce water loss, the Commissionerate of Municipal Administration (CMA) has decided to adopt the concept of District Metered Area (DMA) in all municipal corporations, including Tiruchi and Thanjavur, in the State.

The move comes after complaints of irregular or improper water supply in various cities and towns across the State.

The complaints are mainly the result of improper design of existing drinking water schemes, G. Prakash, Commissioner of Municipal Administration, told The Hindu. Hence, in order to reduce grievances and improve efficiency of water supply, it has been decided to switch over to DMA concept, a distribution network to monitor supply by water metres, he said.

Under the DMA concept, water supply areas in cities will be divided into zones to ensure effective provision to households and commercial establishments through monitoring from Supervisory Control And Data Acquisition (SCADA) control rooms.

Corporations such as Coimbatore, Tirupur, Erode and Tiruchi have attained pan city coverage in drinking water supply to residents. However, modifications will be made to bring the distribution network under DMAs.

The existing networks will be given value added changes wherever needed. The system will enable officials to gauge the quantum of supply to citizens. Besides, it will ensure optimum pressure and steady flow to households.

The new system, Mr. Prakash said, will have a pressure management mechanism to reduce water losses by decreasing background, reported and unreported leakage.

Unnecessary or excess pressure will be reduced. It will eliminate strong pressure fluctuations and prevent leaks.

Since supply will be monitored on real time basis from SCADA control rooms, leaks can be detected easily and remedial measures taken. Officials of all corporations, including Thanjavur, Dindigul and Tirunelveli, have been asked to take steps to bring their water distribution system under the DMA concept.
