Society & RWA Tank Cleaning in Dwarka Sector 13

Society & RWA tanks in Dwarka Sector 13

Sector 13 carries its own Blue Line metro station and the landmark Radisson Blu hotel, with cooperative group housing societies forming the residential bulk. Those society towers use overhead tanks combined with large underground sumps that feed every flat, all managed by their RWAs and AOAs. Water comes as the standard Dwarka 50-50 of Sonia Vihar DJB pipeline and DDA borewells, hard and high-TDS, so borewell hardness leaves scale that thickens quickly at the base.

Around the Radisson Blu and metro, Sector 13’s societies keep their tanks steadily loaded, and our survey counts the full bank before we plan a clean that keeps every tower supplied. Large sumps are where borewell scale settles thickest, so a fixed cycle stops that buildup before it hardens into a crust. Residents can add our water tank cleaning in Dwarka Sector 13 for their own storage on the same day.

Why large society sumps in Sector 13 build scale that hardens fast

The CGHS towers near the Radisson Blu store water in large underground sumps before pumping up to rooftop tanks, and those sumps sit in constant contact with hard borewell-blended water. Calcium and iron drop out of that water onto the sump walls and floor, and in three to four months a firm scale crust plus a soft sludge bed forms. Because the pump draws from near the floor, that sediment gets stirred back into the supply feeding every flat.

On a 3–4 month cycle the scale is lifted while it is still soft, so cleaning is quick and the water stays clear; left for a year it hardens into a crust that has to be chipped out over long downtime. For the AOA the quarterly job is a documented, predictable line item rather than a crisis. We isolate and drain each tank in turn, desludge, jet wash and hand-scrub the walls, apply food-grade disinfectant, then refill and confirm supply before moving on.

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 13 customers

“Can a society near the Radisson Blu be fully cleaned in one booking?” Yes. On the survey we count the large sumps and overhead tanks across the society’s towers and plan a running order so no block loses supply for long. Larger societies are spread over two days, with one certificate covering the job. Every tank gets before and after photos.

“Will hardened scale in our sump be fully removed?” Yes. Even a firm crust from a long-neglected sump comes off with our jet wash and hand-scrub, though the first clean takes longer than a maintained one. That is why we recommend a fixed cycle afterward, so the scale never rebuilds to that thickness. You see the result in the before and after photos.

“Will supply be cut to the flats 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 long. Near the metro and hotel we schedule around the society’s pumping hours.

“Do you give a certificate for the society 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 13 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 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.
