Metro Water supply-day desk
Editorial patterns by north / central / south / OMR / west. Confirm today’s shutdown on the CMWSSB site.
Disclaimer: Civic guidance for residents of Greater Chennai. Official zone, ward, tax, and complaint data live on GCC and agency portals. We do not replace municipal applications or claim live complaint status. Not an official CMWSSB schedule. Area notices on the Corporation / Metro Water sites win.
Editorial supply-day patterns — not today’s valve timings. Confirm shutdowns on the CMWSSB site. Helpline 044 4567 4567 (verify on your bill).
North (Tondiarpet–Manali belt)
Many pockets still run on notified supply days rather than 24×7. Overhead tanks and sumps are the household buffer.
Watch: Industrial demand nearby; summer notices often tighten hours first here.
Tip: Note your depot / area name as printed on CMWSSB bills — “north Chennai” is too wide for a complaint.
Central (Anna Nagar–Kilpauk–Egmore)
Older piped network with mixed pressure. Flats on higher floors feel cuts first.
Watch: Maintenance shutdowns on trunk mains show up as a morning miss, not a tweet.
Tip: Ask the association if the sump filled; a building pump failure is not a city cut.
South (Adyar–Thiruvanmiyur–Velachery)
Better coverage than the far south-west, still not uniform 24×7 in every lane.
Watch: Canal / lake restoration work can reroute mains for days.
Tip: Keep one day’s drinking water; don’t assume the next tanker is “official” without a CMWSSB marking.
IT corridor (Perungudi–Sholinganallur)
Layout growth outruns mains. Many apartments mix Metro Water days with private tankers.
Watch: New layouts: confirm whether the connection is CMWSSB or a local body / private.
Tip: Tanker receipts should name the supplier. Unmarked tankers are a quality risk, not a city schedule.
West (Porur–Ambattur–Maduravoyal)
Suburban expansion; supply hours vary by scheme and booster.
Watch: Monsoon turbidity complaints after the first heavy spell.
Tip: Boil or filter if the water looks muddy after rain — then file with CMWSSB, don’t only WhatsApp the group.

Separate building vs city
If the street has water and your overhead tank is empty, start with the association pump / plumber.

FAQ
Do you publish today’s valve timings?
No. Timings change with maintenance. Use CMWSSB notices. This page explains how Chennai supply usually works by corridor.
Is tanker water the same as Metro Water?
Not always. Official CMWSSB tankers and private tankers are different. Ask for the supplier name and don’t pay cash to an unmarked lorry for “Corporation water”.
