Water Tank Disinfection Explained

We clean shared and single tanks across Rohini Sector 34 DDA LIG blocks, plotted kothis and market buildings — same day where possible. Starting ₹699.
Sector 34 mixes rows of DDA LIG flats with plotted kothis and a small sector market. The LIG stacks share compact overhead tanks feeding a handful of flats each, and because the tanks are smaller they clog with sediment faster when the DJB pressure is low and residents lean on borewell top-up. The plotted kothis run the familiar sump-plus-rooftop setup. Across both we see moderately hard water leaving scale and a reddish-brown grit at the tank base. Low-lying LIG tanks also tend to trap more airborne dust because the lids are old and loose, so we replace or reseat lids where needed after cleaning.
The LIG blocks have narrow internal lanes, so we bring compact hose runs and coordinate roof access through the block RWA. Sector 34 slots go out mid-morning; a shared LIG tank clean is quick at around 90 minutes.
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 DDA LIG blocks in Sector 34 share smaller overhead tanks than the bigger societies elsewhere, but they clog just as fast because low DJB pressure means more borewell top-up and more grit. A shared LIG-stack tank clean runs ₹2,500-3,000, and split across the flats on the stack that works out to roughly ₹120-180 per flat. We drain, vacuum the reddish sediment, scrub, descale the scale line and disinfect, then reseat or replace the loose lid so dust stays out. Twice-yearly cleaning keeps these compact tanks from silting up.
Sector 34's plotted kothis and the buildings around the sector market run their own tanks separate from the LIG scheme. A single rooftop tank on a kothi starts at ₹699, and a sump-plus-overhead clean for a whole house is ₹2,500-3,000, with a ₹300-500 descaling add-on where the borewell scale is thick. Market buildings with a ground sump feeding shop floors take the same combo band. A single owner can book without waiting for neighbours, which fits the varied ownership on these streets.
“Our Sector 34 LIG tank is small — is it cheaper to clean?” The shared-stack rate is ₹2,500-3,000 regardless of the smaller size, but split across the flats it comes to about ₹120-180 each. A single private rooftop tank starts at ₹699.
“The tank lid on our LIG block is broken — can you fix it?” We reseat or replace loose and broken lids as part of the clean so dust and insects stay out; ask the crew and they will sort it on the visit.
“Do you descale the borewell scaling on Sector 34 kothis?” Yes, descaling is a ₹300-500 add-on on top of the base clean, depending on how heavy the scale line is.
