Society & RWA water tank cleaning in Dwarka Sector 20 — we clean the large overhead tanks and sumps in the CGHS towers on the airport side of Dwarka, at about ₹1,500–2,000 per tank for a whole society.
Sector 20 is a newer-developed sector toward the airport side of Dwarka, mixing cooperative group housing societies with institutional and still-developing plots. The society towers rely on large overhead tanks and underground sumps that feed every flat, managed by their RWAs and AOAs. Water follows the Dwarka pattern of Sonia Vihar DJB pipeline supply blended with DDA borewells, hard and high in TDS, so the borewell share leaves scale that builds up between cleanings.
On the airport side, where the sector is still filling in around newer societies, our survey counts the full bank of tanks before we plan a clean that keeps every tower supplied. Newer tanks are not exempt from scale — the hard borewell-blended water lays it down from the first season — so an early fixed cycle keeps them clear from the start. Residents can add our water tank cleaning in Dwarka Sector 20 for their own storage on the same day.
The newer CGHS towers on Dwarka’s airport side draw the same hard borewell-blended supply as the older sectors, so their large sumps and overhead tanks start collecting scale and grit from the first fills. A new tank looks clean, but calcium and iron settle on its walls within weeks, and in three to four months a sediment bed forms at the sump floor. Because the pump draws from near that floor, the settled layer soon recirculates into the supply feeding the flats.
Starting a 3–4 month cycle while a society is new keeps its tanks clear from the outset and avoids the heavy first clean that neglected tanks eventually need. For the AOA it is a light, documented routine and a good habit to lock in early. 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.
No travel charge anywhere in Dwarka Sector 20. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Dwarka Sector 20 — and there’s no travel charge to any of them:
“Does a newer society in Sector 20 really need tank cleaning already?” Yes. New tanks collect borewell scale from the first season, because the hard water here lays down calcium and iron regardless of how new the concrete or plastic is. Starting the 3 to 4 month cycle early keeps a new society’s tanks clear and avoids a heavy first clean later. Each visit on a maintained tank is quick and inexpensive.
“Can our whole society be 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. Newer societies are usually done in a day or two. Every tank gets before and after photos and one certificate.
“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. We schedule around the society’s pumping hours.
“Do you provide a certificate for the AOA 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 20 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 roughly ₹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.
