Society & RWA Tank Cleaning in Dwarka Sector 11

Society & RWA tanks in Dwarka Sector 11

Well connected by its Blue Line metro station and sitting beside the Sector 12 district centre, Sector 11 is largely cooperative group housing society towers with some DDA housing. Those societies run large overhead tanks and underground sumps that feed every flat under continuous high use, all managed by their RWAs and AOAs. The supply is the standard Dwarka blend of Sonia Vihar DJB pipeline water and DDA borewells, consistently hard and high-TDS, so borewell scale and sediment collect steadily.

With the district centre and metro next door, Sector 11’s societies keep their tanks in constant use, and our survey counts the full bank before we plan a clean that keeps every tower supplied. Continuous high use is precisely what silts a large tank on a predictable schedule, so a fixed cycle keeps the water clear and the pumps healthy. Residents can add our water tank cleaning in Dwarka Sector 11 for their own storage on the same day.

Why continuously used society tanks in Sector 11 build sediment on schedule

The large CGHS towers beside the Sector 12 district centre keep their sumps and overhead tanks working almost around the clock, so a large volume of hard borewell-blended water passes through them daily. That constant flow keeps depositing calcium, iron and grit, and in three to four months a busy society’s sump holds a substantial sediment bed. Because the pump draws from near the sump floor, once that bed forms it recirculates into the supply the flats rely on.

A quarterly cycle matches the pace at which these tanks silt, keeping the water clear and each cleaning short because the sediment never hardens into a crust. For the AOA it is a routine, minuted line item with photographic proof, priced ahead rather than paid for in a crisis. 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 tank in the bank.

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 11 customers

“Can a large Sector 11 society be cleaned without interrupting residents?” Yes. We isolate one tank at a time and work around the pumping schedule, so while a tank is drained and disinfected the other towers keep supplying their flats. Large societies beside the district centre are usually spread over two days to keep each riser’s downtime short. Every tank gets before and after photos.

“How often should a continuously used society here clean its tanks?” Every 3 to 4 months, because the near-constant use combined with hard borewell water builds sediment fast. Societies that have skipped cleaning should start with a full desludge of sump and overhead tanks, then hold the quarterly cycle. Most AOAs run an annual AMC so the visits are booked and rate-locked in advance.

“Will you clean the underground sumps as well as the overhead tanks?” Yes. The sump is where most sediment settles, so we clean it along with the rooftop tanks as one chain for each tower. Both appear in the certificate and photo set. In continuously used towers the sump silts fastest, so it is central to the job.

“Do you give a certificate for the society maintenance file?” Yes. Each job closes with a dated RWA or AOA certificate listing every tank cleaned, its capacity, the disinfectant used and the crew, with the photo record. Sector 11 committees keep it on file for residents and audits. It is issued the same day.

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