We clean overhead tanks and sumps for Sector 29's plotted kothis, DDA MIG blocks and builder floors — same day where possible. Starting ₹699.
Sector 29 is a plotted-heavy pocket of Rohini — independent kothis, some DDA MIG blocks and a growing number of builder floors replacing older plots. The kothis run a personal overhead tank plus a ground sump, and being individually owned they often go long stretches without a clean. The MIG blocks share mid-sized tanks between a handful of flats. Water is DJB piped and moderately hard, and the recurring headache in Sector 29 is float-valve and wall scaling from the harder pockets, which stiffens the ballcock so tanks overflow or run dry. Builder floors add the usual post-construction dust in new tanks.
Sector 29's plotted lanes are easy to service, so kothi and builder-floor jobs usually go same-day when booked in the morning. For MIG blocks we ask one flat-owner to open the terrace and coordinate the neighbours.
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.
A very common Sector 29 problem is a tank that either overflows or won't fill because the float valve has seized up with hard-water scale — the ballcock can't move freely against the chalky crust. When we clean a kothi overhead tank here we scrub the walls, vacuum the sludge, and descale the float valve and inlet so the ballcock swings freely again. A single kothi overhead tank is ₹699-1,499 by size, with the descaling step adding ₹300-500 where the scaling is heavy. Sorting the float at the same time saves a separate plumber visit.
For Sector 29 kothis that haven't touched their ground sump in years, we do the overhead tank and sump together so the clean roof tank isn't re-contaminated from below — a combo runs ₹4,500-6,000 depending on capacities, or the sump alone is ₹1,500-2,500. On the builder-floor side, a new owner should get a move-in clean before shifting, since fresh tanks carry construction dust and pipe offcuts; a single builder-floor tank is ₹699-1,499 and we can usually fit it within a day of the call.
“Our Sector 29 tank keeps overflowing — is that a cleaning issue?” Often yes. Hard-water scale seizes the float valve so it can't shut off. We descale the valve and inlet during the clean for ₹300-500 on top of the ₹699-1,499 tank clean, so the ballcock moves freely again.
“Should the kothi sump be cleaned with the roof tank?” Yes, together is best — otherwise the sump re-dirties the clean roof tank. The combo is ₹4,500-6,000, or the sump on its own is ₹1,500-2,500.
“Is same-day possible for a builder floor in Sector 29?” Usually, if you call in the morning. The plotted lanes are quick to reach, and a move-in clean of a single builder-floor tank is ₹699-1,499 by size.
