Society and RWA tank cleaning for the kothis and builder floors of Defence Colony — per-floor overhead tanks and older shared sumps under the parking, cleaned in one coordinated visit with a dated certificate. From ₹1,500 per tank.
Defence Colony is an upmarket A-to-D block colony of independent kothis and premium builder floors laid out along a central nallah. Supply is mainly DJB with some borewells. Each builder floor typically keeps its own overhead tank, while the plot shares an older underground sump tucked under the parking. These are compact shared systems — a few floors per plot rather than a big society — but the sumps are among the oldest tanks in the colony and are opened far too rarely, so silt and scale accumulate quietly beneath the cars.
KaamGenie cleans the whole plot in one visit — the older underground sump under the parking with full confined-space safety, and each builder floor’s rooftop tank — coordinated with the owners or the plot RWA. We ventilate and test the sump before entry, clear the settled silt, jet and scrub the walls, disinfect, and hand over one dated certificate the floors can share. For a single tank, see water tank cleaning in Defence Colony. This page is specifically about society and RWA whole-building tank cleaning.
The shared sump under a Defence Colony plot sits below the parking, out of sight and out of mind, which is exactly why it silts up. It takes the first DJB fill and any borewell water, so sediment and hardness settle thickest there before the pump lifts it to each floor’s rooftop tank. A neglected sump quietly feeds cloudy water to every household on the plot. Cleaning the sump and floor tanks every three to four months keeps the shared supply clear for all the floors.
With several independent builder-floor owners on one Defence Colony plot, tank cleaning tends to fall through the cracks — nobody owns the shared sump, so it goes unopened for years. We take the coordination off their hands: one survey, one visit that clears the sump and every floor tank, and a single certificate the owners split. Doing it all together is cheaper than separate call-outs, and an annual AMC of four visits keeps the old sump under the parking from ever silting up badly again.
No travel charge anywhere in Defence Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Defence Colony — and there’s no travel charge to any of them:
“Do you clean shared plot tanks in the C Block of Defence Colony?” Yes. We regularly clean Defence Colony builder-floor plots across the A-to-D blocks, covering the older underground sump beneath the parking and each floor’s rooftop tank. A short survey checks the sump’s age and access before we agree a single coordinated visit with the plot owners or RWA.
“What does it cost to clean a whole plot in Defence Colony?” Rooftop tanks of 2,000 to 3,000 litres are ₹1,500 to ₹2,000 each, and the shared sump is quoted by capacity. Since a Defence Colony plot has one sump plus a few floor tanks, we bulk-quote them together, usually 15 to 20 percent off the per-tank rate for cleaning the whole plot in one visit.
“Can one builder-floor owner book if the others have not?” Yes. A single owner can book their own rooftop tank without waiting for the plot to agree, and we give a dated certificate. The shared sump under the parking needs the owners to agree jointly, since it feeds every floor, and we can bring one quote covering the sump plus all the floor tanks.
“How do you work around the plot’s water schedule?” We isolate and drain one tank at a time around the DJB fill and pump timing noted during the survey, so the floors above keep supply. We typically clean the shared sump first, refill it, then take each floor’s rooftop tank in turn, finishing a Defence Colony plot in a day and confirming supply is normal.
“Do you offer an AMC for Defence Colony plots?” Yes. The AMC covers four visits a year for the plot’s sump and all rooftop tanks at 20 to 25 percent off the per-visit rate. Because these old under-parking sumps silt up when ignored, quarterly cleaning is worth it, and each visit ends with a dated certificate the builder-floor owners can keep on file.
