Society and RWA tank cleaning in Sheikh Sarai, built for the Phase 1 and Phase 2 DDA societies whose shared overhead tanks and plot-level sumps feed every flat. One visit for the whole society, dated certificate for the RWA. From ₹1,500 per tank.
Sheikh Sarai is a genuine society neighbourhood — the DDA flats of Phase 1 and Phase 2 with builder floors mixed in, near Malviya Nagar and Chirag Delhi. Most blocks share a bank of overhead tanks on the terrace and a plot-level underground sump plumbed to serve every flat. On DJB with borewell backup, those shared tanks handle the whole society’s daily water, and because the blocks are large, one neglected tank affects a lot of families at the same time.
Because a single sump and its terrace tanks feed dozens of flats, cleaning them together as a society job is far more sensible than each family sorting its own supply. For a one-off household tank, our general water tank cleaning in Sheikh Sarai page covers it. This page is specifically about society and RWA (whole-building) tank cleaning — the full bank of shared tanks and the sump cleaned in one coordinated visit for the RWA.
A DDA block here runs everything through one sump and a set of terrace tanks, so the combined draw of every family passes through the same water each day. Silt from DJB and minerals from the borewell settle in the sump first, then ride up to the overhead tanks. In three to four months that settled layer becomes sludge and biofilm, and since there is no filter after the terrace tanks, it reaches every flat’s kitchen across the block.
RWAs here juggle parking, lifts and security, and tank cleaning quietly falls off the list for a year or more. Doing the whole society in one booking spreads the cost thinly across all the flats and finishes in a single visit rather than block-by-block disruption. A quarterly AMC takes the decision off the committee, with a dated certificate filed after each round — useful when residents ask about water quality.
No travel charge anywhere in Sheikh Sarai. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Sheikh Sarai — and there’s no travel charge to any of them:
“Do you clean the DDA societies in Sheikh Sarai Phase 1 and Phase 2?” Yes. We regularly service the shared overhead tanks and plot-level sumps across the Sheikh Sarai Phase 1 and Phase 2 DDA blocks and the builder floors toward Chirag Delhi. We survey the terrace tanks and the sump together, clean the whole society in one visit, and give the RWA a dated certificate.
“How much to clean a whole society’s tanks here?” Each shared overhead tank of 2,000 to 3,000 litres is ₹1,500 to ₹2,000, and the underground sump is quoted by capacity. Booked as one whole-society visit, the bulk rate is usually 15 to 20 percent below per-tank pricing. We confirm the figure once the tanks are counted on site.
“Can one flat owner book if the RWA has not arranged it?” Yes. If your society committee has not scheduled cleaning, any resident can call 95603 66362. We can do your individual flat tank, but since the sump and terrace tanks are shared, we usually suggest raising it with the RWA so the whole block benefits from one visit.
“How do you work around the society’s water timings?” We ask the caretaker when the sump fills and when the pumps lift water to the terrace, then plan around that cycle. Tanks are cleaned one at a time and refilled straight after, so supply to the flats is barely interrupted and no block is left without water through the day.
“Is there an AMC for the whole society?” Yes. Our society AMC covers the full bank of overhead tanks and the underground sump four times a year, about quarterly. It is priced 20 to 25 percent below single visits, and after each round the RWA gets before-and-after photos and a dated certificate for the maintenance file.
