Water Tank Cleaning Methods Explained

We clean individual builder-floor tanks, plotted-house tanks and society sumps across the plotted and group-housing pockets of Dwarka Sector 28, same day where possible. Starting ₹699.
Sector 28 is a plotted-and-builder-floor sector with rows of independent floors, some plotted kothis and a handful of CGHS societies at the edges. The plotted floors mostly carry their own 500-1,500L terrace or loft tank, one per floor, while the societies keep the standard shared overhead tank and sump. Supply is DJB piped with borewell backup, and on the plotted side we regularly open tanks that were filled at possession and never cleaned since, thick with sediment and, where lids don't seal, algae. Because ownership is per-floor, no single person feels responsible for the tank until the water goes bad.
Sector 28's tightly packed plotted rows suit same-day individual bookings — the crew can clean four or five floor tanks in one street on a single visit. For the edge societies we plan the shared-tank work a little ahead so the block gets notice of the water cut.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.
The defining Sector 28 job is a builder floor whose terrace tank hasn't been opened since the building was handed over, sitting on years of sediment. We open and fully drain it, scrub the walls and floor, vacuum out the sludge, clear any scale and sanitise before refilling. An individual floor tank is ₹699-1,499 depending on size and access, and we can nearly always do it same day. When neighbours on a row book together, or a plot owner wants all its floors done, we chain them in one visit at a per-tank rate — which brings the cost down and gets the whole building fresh at once.
The CGHS societies at the edges of Sector 28 run the usual shared overhead tank and underground sump, and their RWAs book either the overhead alone at ₹2,500-3,000 or the overhead-plus-sump combo at ₹4,500-6,000, roughly ₹120-180 a flat for the year. Move-in cleans are common across Sector 28 because plotted floors change hands often — we get the tank drained, scrubbed and sanitised before the new family shifts in. We finish every job with a food-safe sanitising step and hand over photos so owners have a record.
“Our floor's tank was never cleaned since possession — is that bad?” It usually means years of sediment at the bottom; we drain, scrub, vacuum the sludge and sanitise. An individual floor tank is ₹699-1,499, usually same day.
“Can several floors on our row book together?” Yes, we chain neighbouring floor tanks in one visit at a per-tank rate, which lowers the cost and gets the whole row done at once.
“Do you clean before a new tenant or buyer moves in?” Yes, a move-in clean is a full drain, scrub, sludge removal and sanitise so the tank is fresh; we can usually fit it same day.
