The Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) has stepped up measures to monitor the quality of drinking water to prevent contamination during the monsoon season.
Depot engineers and deputy area engineers will monitor residual chlorine level in at least 2,000 locations. In case of contamination, the pipeline system will be segregated and mobile water supply will be arranged for the affected location or street.
If any major leak or burst occurs, the valves will be closed properly to avoid flow of contaminated water.
The process control lab, under the supervision of the chief chemist of water treatment plant, will monitor water quality intensively.
The board has instructed area engineers to monitor water quality on supply days — Tuesdays or Wednesdays — jointly with assistant health officers from the Chennai Corporation and hold review meetings on Friday.
CMWSSB has set up a round-the-clock central complaint cell (Tel: 45674567 and 28454040) at its head office in Chintadripet. Complaints will be conveyed immediately to the respective officer and addressed.
A special committee has been formed to inspect the activities of all areas, the release said.
Following instructions to desilt sewage network where obstructions occur frequently, CMWSSB has desilted 68 km of sewage pipeline and will take up desilting works on 65 km of sewer line from October 25 to November 30.
Instructions have been given that all 218 pumping stations should be in a position to operate continuously and generators kept ready in case of power failure.
