Society & RWA Tank Cleaning in Dwarka Sector 9

Society & RWA tanks in Dwarka Sector 9

Sector 9 is a metro-connected sector on the Blue Line with a strong commercial frontage and a cluster of CGHS towers behind it. Those high-rise societies run overhead tanks paired with underground sumps that feed every flat, all managed by their RWAs and AOAs. Its water is the standard Dwarka 50-50 of Sonia Vihar DJB pipeline and DDA borewells, both hard and mineral-laden, so scale and grit settle steadily inside the tanks.

Behind the commercial frontage the residential towers run tall, and our survey counts the full bank of sump and overhead tanks before we schedule a clean that keeps the upper floors supplied. High-rise societies especially benefit from a fixed cycle because a fouled tank at height means weak, discoloured supply to the flats furthest up the riser. Residents can add our water tank cleaning in Dwarka Sector 9 for their own storage on the same visit.

Why high-rise societies in Sector 9 need their tanks kept clear

In the tall CGHS towers of Sector 9, water is pumped from a basement sump up to rooftop overhead tanks and then distributed down the riser, so sediment at either stage travels to every flat. The hard borewell-blended supply keeps depositing scale and grit, and in three to four months a busy tower’s sump can hold a heavy sediment bed. In a high-rise, low pressure from a partly choked outlet hits the top flats first, so a fouled tank shows up quickly as a resident complaint.

A quarterly cycle keeps both the sump and the rooftop tanks clear, so the pumps stay efficient and the flats at height keep full pressure and clean water. For the AOA it is a documented, routine job rather than an emergency call 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 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 9 customers

“Can a high-rise society in Sector 9 be cleaned without cutting supply to the top floors?” Yes. We isolate one tank at a time and work around the pumping schedule, so while a rooftop tank is drained and disinfected the other towers keep supplying their flats. On tall towers we time the work to the low-draw window so the top-floor flats are barely affected. Each tank gets before and after photos.

“How often should a high-rise society here clean its tanks?” Every 3 to 4 months, because the volume these towers turn over combined with hard borewell water builds sediment fast, and the top flats feel a fouled tank first. Societies that have skipped cleaning should begin with a full desludge of sump and overhead tanks. Most AOAs run an annual AMC so the quarterly visits are pre-booked.

“Will you clean the basement sump as well?” Yes. The sump is where most grit settles, so we clean it along with the rooftop tanks as one chain for each tower. Both appear in the certificate and photo record. In a high-rise a silted sump is the usual cause of weak upper-floor supply, so it is central to the job.

“Do you give a certificate for the society file?” Yes. Every job closes with a dated RWA or AOA certificate listing each tank, its capacity, the disinfectant used and the crew, with the photo set. Sector 9 committees keep it in the maintenance file for residents and audits. It is issued the same day.

“What is the bulk rate 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 high-rise sumps sit at the upper end, confirmed on the survey. No call-out fee applies once the society books.
