Overhead (rooftop) tank cleaning in Dwarka Sector 20 — drained, desludged and disinfected across its newer society towers toward the airport side. From ₹699.
Sector 20 is a newer-developed sector toward the airport side of Dwarka, mixing cooperative group housing society towers with institutional and still-developing plots. On those newer terraces the overhead (rooftop) tank is the last stop before your tap, and no filter cleans the water once it leaves the tank. Even in a modern building, the hard Dwarka borewell supply leaves a chalky scale on the walls and a gritty sludge at the base between cleanings. Our crew drains, scoops and jet-washes each tank back to a clean floor.
The tanks here run the standard Dwarka pattern of Sonia Vihar DJB pipeline supply blended with DDA borewells, hard and high in TDS, so a new tank starts collecting sediment from its first season. In a society tower toward the airport side, one large rooftop tank feeds many flats, so its condition affects a whole line of homes. We service the big society overheads and any DDA-side tanks alike, bookable with our wider water tank cleaning in Dwarka Sector 20. Every job ends with before and after photos and a dated certificate.
A newer sector like 20 often has residents assuming a modern tank stays clean on its own, but it draws the same hard, high-TDS Dwarka borewell mix as the older sectors, and those dissolved minerals settle out as scale the moment the water is still. In still-developing pockets the pipeline pressure can be uneven, so tanks lean more on the borewell share that carries the most sediment. The tanks sit exposed on the terraces toward the open airport side, where dust from ongoing construction settles readily into the lids. A new tank is clean only until its first few fills.
Because the rooftop tank is the last barrier before the tap, that scale and construction-borne grit are not filtered out — they reach kitchens and bathrooms directly, and settled sludge is where biofilm and bacteria establish. We clear it fully: drain the tank, hand-scoop the sludge, high-pressure jet wash the walls and base, hand-scrub the hardened scale, then disinfect with a food-grade solution. We finish with before and after photos and a dated certificate so a society committee in a new tower can start proper maintenance records from the very first clean.
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 brand-new rooftop tank in a Sector 20 society really need cleaning?” Yes. Even a new tank in a Sector 20 tower fills with the same hard, high-TDS Dwarka borewell water, and scale and sediment start settling from the first few fills. In a still-developing pocket, construction dust adds to the grit collecting in the tank. Since the rooftop tank is the last stop before your tap with no filter after it, that buildup reaches you directly. We recommend the first clean within a few months of occupancy and every three to four months after.
“How much does rooftop tank cleaning cost in a Sector 20 flat?” For a standard 1000-litre overhead tank in a Sector 20 society flat, cleaning starts from ₹699. The price depends on tank size and how much borewell sludge and construction grit have built up since the last clean. A single rooftop tank is usually finished within an hour, with before and after photos and a dated certificate included. Larger shared society master tanks are quoted after we see the terrace.
“Do you clean the big shared tanks in the newer Sector 20 towers?” Yes. The newer CGHS society towers in Sector 20 run large shared rooftop tanks feeding many flats, and we clean those as well as individual flat tanks. The managing committee usually books one coordinated visit so the supply is off briefly for everyone at once. We drain, desludge, jet wash and disinfect the full tank, then provide before and after photos and a dated certificate to start the new society’s maintenance records.
“Can you reach Sector 20 for same-day cleaning even though it is on the airport side?” Usually yes — Sector 20 is part of our regular Dwarka route despite sitting toward the airport side, so same-day or next-day slots are commonly available. A morning appointment works best because the tank must be drained before we clean it. The clean of a single rooftop tank is quick once the crew is on the terrace. We confirm the time window at booking so your supply is off only briefly.
“We just moved into a new Sector 20 tower — how do we start proper tank maintenance?” The best start is a first clean of your rooftop tank within a few months of moving in, because the tank has already taken on borewell scale and construction dust from its early fills. From there, cleaning every three to four months keeps the hard Dwarka water from laying down heavy scale. Since the overhead tank is the last point before your tap, this is the single most important step for water quality in a new tower. We give you before and after photos and a dated certificate each time so the society can keep a clean record from the outset.
