Society & RWA water tank cleaning across Kasturba Nagar. We survey and clean the whole building’s bank of shared overhead tanks and underground sumps in one coordinated visit, with a dated RWA certificate for the maintenance file. Bulk pricing for the entire block — typically ₹1,500–2,000 per tank when six or more are done together.
Kasturba Nagar is a settled residential colony of independent houses and builder floors near Lajpat Nagar and South Extension, where rebuilt floor-blocks and small apartment buildings commonly share a tank bank. Supply is predominantly DJB pipeline water with borewell backup, and quality is generally moderate. Building committees and RWAs here run rooftop overhead tanks with underground sumps that feed several flats from one point.
Ordinary sediment and dust make routine cleaning worthwhile even with moderate water, and one neglected sump reaches every floor above it. We clean the whole bank in one planned visit, the same crew and standard behind our water tank cleaning in Kasturba Nagar, scaled up for society-sized storage. One survey, one schedule and a dated certificate for the RWA.
Even on moderate DJB water, a shared sump feeding several flats accumulates sediment and dust that settles at the bottom where booster pumps draw from. Redeveloped builder floors here often add tanks without anyone taking charge of cleaning them, so the storage sits untouched for years. Cleaning every 3–4 months keeps the shared bank clear rather than letting a hidden sludge layer form.
For an RWA, doing it once for the whole building beats flat-by-flat cleaning. We survey and count the tanks, isolate and drain each in turn so supply is never cut off across the block, strip the sediment, jet-wash and hand-scrub, then disinfect each tank with food-grade solution. Before-and-after photos and a dated certificate make the quarterly clean an easy approval at the RWA meeting.
No travel charge anywhere in Kasturba Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Kasturba Nagar — and there’s no travel charge to any of them:
“Can you clean our whole building’s tanks in one visit in Kasturba Nagar?” Yes. We survey to count every overhead tank and sump the block shares, then clean them all in one coordinated visit. For a typical rebuilt builder floor with two or three shared tanks that is a single half-day. The RWA gets one certificate covering the whole building.
“Will the flats lose water while you clean the tanks?” No. We isolate and drain one tank at a time and keep the others feeding the block, so no flat is fully cut off. Most Kasturba Nagar buildings hold enough overhead buffer that residents do not notice. We time it around the DJB supply hours so pumps refill normally.
“The water here is fairly clean — do we still need regular cleaning?” Yes. Even on moderate DJB water, a shared sump feeding several flats collects sediment and dust at the bottom where the pump draws from. We recommend every 3–4 months so the shared bank never develops a hidden sludge layer. Redeveloped floors that added tanks without a cleaning plan especially benefit.
“Do you provide an RWA certificate for the maintenance file?” Yes. Every job ends with a dated cleaning certificate listing each tank cleaned plus before-and-after photos. RWAs near Andrewsganj use it to show residents the shared storage is maintained and to keep a record between cleans. It is issued in the society’s name.
“What is the bulk price for six to eight shared tanks?” For a full bank of six or more tanks we charge roughly ₹1,500–2,000 per tank rather than one flat figure, since sizes differ. Doing the whole building together lowers the per-tank rate. We give the RWA a firm quote after the survey, and an AMC locks the rate for the year.
