Society & RWA Tank Cleaning in Dwarka Sector 17

Society & RWA tanks in Dwarka Sector 17

Sector 17 is a mixed residential sector of DDA flats and cooperative group housing societies set among institutional plots. Rooftop overhead tanks serve the DDA housing while the society towers use larger overhead and underground sump systems, all managed by their RWAs and AOAs. The supply is the familiar Dwarka blend of Sonia Vihar DJB pipeline and DDA borewells, leaving it hard and high in dissolved solids, so every tank is prone to borewell scale buildup.

With DDA blocks and society towers side by side, Sector 17 has a mix of tank types, and our survey counts them all before we plan a clean that keeps each set of flats supplied. Whether rooftop tank or basement sump, the hard water here lays scale on a predictable rhythm that a fixed cycle keeps in check. Residents can add our water tank cleaning in Dwarka Sector 17 for their own storage on the same visit.

Why the mixed DDA and society tanks of Sector 17 all need routine cleaning

Sector 17 runs two kinds of shared storage side by side — the rooftop overhead tanks on the DDA blocks and the sump-plus-overhead systems in the CGHS towers — and both draw the same hard borewell-blended supply. That water keeps depositing scale and grit, and in three to four months a rooftop tank builds a soft sludge floor while a society sump builds a heavier sediment bed. In each case the settled layer stirs back into the supply feeding the flats above.

A 3–4 month cycle keeps every tank type in the sector clear, and because the block and society tanks foul at similar rates it is easy to book them on a shared schedule. For the RWA it is a routine, documented job rather than a reactive one. We isolate and drain each tank in turn, desludge, jet wash and hand-scrub, apply food-grade disinfectant, then refill and confirm supply before moving to the next.

How we do it — our 8-step process

• 1. Site survey & schedule We count the tanks, check access and the water-supply timing, and agree a slot that doesn’t cut off the building.
• 2. Isolate & drain Each tank is isolated and drained in turn so supply to flats is disrupted as little as possible.
• 3. Sludge & sediment removal Settled sludge is scooped and wet-vacuumed from every overhead and underground tank.
• 4. High-pressure jet wash Walls, floor and ceiling of each tank are jet-washed to remove scale and biofilm.
• 5. Manual scrub Corners, joints and inlet/outlet mouths are hand-scrubbed across all tanks.
• 6. Anti-bacterial treatment A food-grade disinfectant wash sanitises every tank before refill.
• 7. Refill & supply check Tanks are refilled and we confirm supply to the flats is back to normal.
• 8. Photos & RWA certificate Before/after photos of each tank and a dated certificate for the society’s maintenance file.

Common questions from Dwarka Sector 17 customers

“Can both the DDA block tanks and the society tanks in Sector 17 be booked together?” Yes. On the survey we count the rooftop tanks on the DDA blocks and the sump-and-overhead systems in the CGHS towers, and plan a running order so no set of flats loses supply for long. Booking them together means one coordinated visit. Each tank gets before and after photos and one certificate.

“Will supply be cut to the flats during the clean?” Only the tank being worked on is isolated at any time, while every other tank keeps supplying its flats. We refill and confirm each tank before opening the next, so no riser stays dry for more than an hour or two. We schedule around the block or society pumping hours.

“Do you give a certificate for the maintenance file?” Yes. Every job closes with a dated RWA or AOA certificate listing each tank cleaned, its capacity, the disinfectant used and the crew, with the photo record. Sector 17 committees keep it on file for residents and audits. It is issued the same day.

“How often should societies and DDA blocks here clean their tanks?” Every 3 to 4 months, because the hard borewell-blended water lays scale down quickly in both tank types. Blocks and societies that have skipped cleaning should begin with a full desludge, then hold the quarterly cycle. Most RWAs run an annual AMC so the visits are pre-booked.

“What is the bulk price for 8 to 10 tanks?” At about ₹1,500–2,000 per tank, a bank of 8 to 10 done together is quoted at a bundled rate below the per-tank total. Society sumps sit at the upper end and rooftop block tanks lower, confirmed on the survey. No call-out fee applies once the job is booked.
