Society & RWA Tank Cleaning in Dwarka Sector 19

Society & RWA tanks in Dwarka Sector 19

Sector 19 mixes DDA housing with cooperative group housing societies on the sub-city’s western side, part residential and part institutional. The DDA blocks use rooftop overhead tanks and the CGHS towers use overhead-plus-sump systems, all managed by their RWAs and AOAs. Its water is the usual Dwarka 50-50 of Sonia Vihar DJB pipeline and DDA borewells, both hard and mineral-heavy, so the tanks trap borewell sediment and scale over time.

On the western side, where the sector runs part residential and part institutional, our survey counts every tank in the bank before we plan a clean that keeps each set of flats supplied. Both the rooftop block tanks and the society sumps foul on a predictable rhythm here, which a fixed cycle keeps in check. Residents can add our water tank cleaning in Dwarka Sector 19 for their own storage on the same visit.

Why western-side societies in Sector 19 should not let tanks silt up

On the western edge of the sub-city, Sector 19’s societies and DDA blocks all draw the same hard borewell-blended supply into shared sumps and overhead tanks. That water keeps depositing scale and grit, and in three to four months a society sump builds a sediment bed while a rooftop tank builds a sludge floor. Because the pumps draw from near the bottom, once that layer forms it recirculates into the supply feeding the flats.

A 3–4 month cycle keeps every tank in the sector clear and each cleaning quick, since sediment removed early never hardens into a crust. For the RWA it is a routine, documented line item rather than a reactive scramble when a tank fouls. 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 19 customers

“Can our western-side society in Sector 19 be cleaned in one booking?” Yes. On the survey we count the sumps and overhead tanks across the society’s towers and the rooftop tanks on any DDA blocks, then plan a running order so no set of flats is dry for long. Most jobs here finish in a day or two. Every tank gets before and after photos and one certificate.

“Will supply be cut during the clean?” Only the tank being cleaned 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 RWA 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 19 committees keep it on file for residents and audits. It is issued the same day.

“How often should a society here clean its tanks?” Every 3 to 4 months, because the hard borewell-blended water lays scale down quickly in both the block and society tanks. Those 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 and rate-locked.

“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.
