Water Tank Cleaning in Dwarka Sector 21

What we see most in Dwarka Sector 21

Sector 21 sits right on the Blue Line terminus, so it mixes big CGHS group-housing societies with commercial and institutional blocks near the station. Most societies run a shared overhead tank of 5,000-10,000L feeding each stack, plus an underground sump that the booster pump draws from. Supply is DJB piped with society borewell backup, and that borewell water leaves a fine grey sediment and some scaling on tank walls within a few months. We usually find the sump neglected more than the overhead tank because residents rarely see it.

Because Sector 21 is a transit hub, we schedule society jobs early morning or mid-afternoon to work around the pump timings and parking near the station. RWAs here tend to book the whole block at once, so we send a two-person crew and clear a full riser of tanks in one visit.

How long does it take?

For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.

Society overhead-plus-sump cleaning near Sector 21 Metro

A typical request here is from an RWA that hasn't touched the underground sump in over a year while the overhead tank gets a quick rinse now and then. We drain the sump, remove the settled silt and biofilm, scrub the walls, vacuum out the slurry and finish with a food-safe sanitising fog before refilling. A single shared overhead tank runs ₹2,500-3,000; doing the overhead and the sump together as a combo lands around ₹4,500-6,000 depending on sump size. Split across 12-16 flats that is roughly ₹120-180 a flat for the year. We hand the secretary before-and-after photos for the society records.

Individual flats and station-side offices

Not everyone in Sector 21 is on a shared tank — some resale flats and the commercial units near the Metro have their own 500-1,000L loft or terrace tanks. For a single individual tank we charge ₹699-1,499 depending on size and access, and we can usually fit it in same day. Small offices and shops on the market side often want a quiet mid-morning slot so we don't disturb footfall. If a flat is a fresh move-in we do a full drain, scrub and sanitise so the new family starts clean.

Common questions from Dwarka Sector 21 customers

“Do you clean the underground sump as well as the overhead tank?” Yes — the sump is usually the dirtier of the two. A combo overhead-plus-sump clean is ₹4,500-6,000; an overhead tank alone is ₹2,500-3,000.

“How much per flat if our whole society books together?” For a shared overhead tank split across the block it works out to about ₹120-180 per flat for the year, and we clear the full riser in one visit.

“Can you work around the Metro-side parking and pump timings?” Yes, we schedule early morning or mid-afternoon around your booster-pump cycle, and our two-person crew carries its own equipment so we don't block station-side lanes.
