Society & RWA Tank Cleaning in Dwarka Sector 15

Society & RWA tanks in Dwarka Sector 15

Sector 15 is a calmer residential sector of DDA SFS and HIG blocks alongside several cooperative group housing societies. The DDA blocks use rooftop overhead tanks while the CGHS towers run overhead-plus-sump setups, all managed by their RWAs and AOAs. Water is the standard Dwarka mix of Sonia Vihar DJB pipeline supply and DDA borewells, hard and mineral-rich, so borewell scale collects steadily wherever the tanks sit unused between fills.

Because Sector 15 is quieter and its tanks often sit part-full between fills, sediment settles and scale sets in the still water, which our survey looks for first. We count every overhead and underground tank in the bank, then clean them in sequence so no block loses supply for long. Residents can add our water tank cleaning in Dwarka Sector 15 for their own storage on the same visit.

Why quieter society tanks in Sector 15 still need regular cleaning

It is tempting to think a calmer, lower-draw sector like Sector 15 needs less tank cleaning, but the opposite is often true: when a tank sits part-full between fills, the water is still and sediment settles undisturbed onto the floor. Dwarka’s hard borewell-blended supply keeps dropping calcium and iron, and in still water that scale sets firmly on the walls over three to four months. When the tank is topped up and drawn hard again, that settled layer stirs back into the supply.

A 3–4 month cycle keeps even a quiet society’s tanks clear, because scale removed while soft scrubs off easily, whereas scale set in still water for a year turns stubborn. For the SFS block or society RWA it is a light, predictable job with a documented trail. 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 15 customers

“Do quieter SFS blocks in Sector 15 really need tank cleaning as often?” Yes. In fact a lower-draw block can foul just as fast, because still water in a part-full tank lets sediment settle and scale set undisturbed. We recommend the same 3 to 4 month cycle here as in busier sectors. The difference is that a maintained quiet tank is quick and inexpensive to clean each time.

“Can our society and SFS block tanks be cleaned in one visit?” 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 block is dry for long. Most Sector 15 jobs 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 any other tank keeps supplying its flats. We refill and confirm each tank before opening the next, so the interruption is short. In this calmer sector we simply schedule around the block’s fill times.

“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 set. Sector 15 committees keep it on file for residents and audits. It is issued the same day.

“What is the bulk price for 8 to 10 tanks across a block?” 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. Quiet, maintained tanks often sit at the lower end because there is less sludge, confirmed on the survey. No call-out fee applies once the society books.
