Sector 21 is established Noida with a mix of older cooperative group-housing blocks and independent plotted homes — we clean society sumps and rooftop tanks alongside individual house tanks across Sector 21 Noida, from ₹699 onwards.
Sector 21 is one of Noida’s older residential sectors, and besides the usual plotted kothis and builder floors it holds some of the early cooperative group-housing blocks — modest low-rise societies that have been lived in for years. These aren’t the tall tower setups of newer Noida; they’re smaller blocks with an underground sump and a few rooftop tanks shared between the flats, run by a residents’ committee rather than a big facility team.
Those older co-op tanks tend to fall between the cracks — small committees, tight maintenance budgets, and water that’s often been stored and forgotten. We handle them properly: the shared sump and the block’s rooftop tanks cleaned and documented for the committee. And we do the independent plotted homes of Sector 21 the same way — their own overhead tank and sump — so both kinds of household here are covered.
For an older Sector 21 co-op block, a proper clean covers the shared underground sump and the rooftop tanks the flats draw from — drained, scrubbed, vacuumed and disinfected with food-grade chlorine, with a dated record handed to the residents’ committee. These small societies don’t have a facility team to chase it, so we keep it simple: one visit, every shared tank done, and paperwork the committee can show its members. A modest co-op block is usually a half-day job, not the multi-day affair a high-rise needs.
The independent plotted homes of Sector 21 we handle the usual way — the overhead tank from ₹699 and the underground sump priced higher for its size, ideally done together so the whole line is clean. Whether it’s a co-op committee booking the shared tanks or a single kothi owner booking their own, the process and the before/after photos are the same; only the number of tanks changes.
Standard Sector 21 tank: about 90 minutes door-to-door for an overhead tank, 2-3 hours for a combined sump + overhead, and longer for high-rise society reservoirs. We bring everything — vacuums, jet pumps, food-grade chlorine disinfectant, scrubbing brushes, rinse water. After cleaning, before-and-after WhatsApp photos and a GST invoice.
"We’re a small co-op committee in Sector 21 — can you clean our shared sump and rooftop tanks?" Yes — older co-op blocks are a regular part of our Sector 21 work. We clean the shared underground sump and the rooftop tanks in one visit, all drained, scrubbed, vacuumed and disinfected with food-grade chlorine, and hand the committee a dated record to show members. A modest block is usually a half-day job; we’ll quote it on the number and size of tanks.
"Our co-op tanks haven’t been cleaned in a long time — is that a problem?" It’s common in older Sector 21 societies where a small committee has had other priorities, and no, it’s not a problem for us — it’s exactly the kind of neglected tank we open and clear. We’ll show you what was at the bottom before and after, so members can see it was genuinely done, and you can set a sensible schedule from there.
"Do you also clean individual plotted homes in Sector 21, not just societies?" Yes — independent kothis and builder floors are just as much our work here. It’s the overhead tank from ₹699, about 90 minutes, and the underground sump priced higher for its size; doing both together is the sensible way for a plotted home. You get before/after photos and a GST invoice either way.
