Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) will implement the changes following the delimitation of wards from October 1.

It may be recalled that the Greater Chennai Corporation had notified delimitation of wards in 2018. While there is no difference in the number of wards, boundaries of some of the wards have changed.
Residents may contact the new depot offices for any water and sewage related issues. The changes made would help officials of the GCC and the board to coordinate work efficiently, the release said.
