Water Tank Cleaning in Rohini Sector 25

What we see most in Rohini Sector 25

Sector 25 is one of Rohini's quieter, more plotted stretches — rows of independent kothis and low-rise DDA MIG blocks off the main road, with fewer big societies than its neighbours. Most kothis run a rooftop overhead tank plus a ground sump, and because these are single-family homes the tanks often get forgotten for a couple of years until the water starts smelling. The DJB supply reaches most lanes but pressure dips at the far ends, so several homes lean on a borewell that leaves the walls scaly. On the DDA MIG side the shared tanks are mid-sized, feeding a handful of flats each.

Sector 25's lanes are calm and easy to work in, so our crews can usually get a kothi done within a day of the call. We ask the owner to keep the terrace and sump-chamber clear so we can start straight away.

How long does it take?

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.

Two-year kothi tanks in Sector 25

A typical Sector 25 call is a family kothi where the overhead tank hasn't been opened in a year or two and the water has picked up an earthy smell — a sure sign of a sludge layer and biofilm on the walls. We drain the tank, hand-scrub every surface to lift the biofilm, vacuum the sludge, then sanitise so the smell is gone for good. A single kothi overhead tank is ₹699-1,499 by size. If the ground sump hasn't been touched either, we clean both together and the pair runs ₹1,500-2,500 more depending on the sump's capacity.

Borewell descaling for far-end lanes

Homes at the far ends of Sector 25 where DJB pressure drops often run a borewell, and that hard water leaves a stubborn chalky scale on tank walls and float valves that a plain wash won't shift. We add a proper descaling step — a mild acid treatment on the walls and fittings — so the float works freely and the water stops tasting metallic. Descaling is ₹300-500 on top of the standard clean, depending on how thick the crust is. For a DDA MIG shared tank on the same lanes, the clean is ₹2,500-3,000 before any descale.

Common questions from Rohini Sector 25 customers

“My kothi tank smells earthy — what's wrong?” That earthy smell is biofilm and sludge from a tank that's gone too long between cleans. A full scrub-and-sanitise of a single Sector 25 kothi tank is ₹699-1,499 and removes it completely.

“We're on a borewell at the lane's far end — do we need extra?” Likely yes. Borewell hard water in those pockets leaves scale that needs descaling, which we add for ₹300-500 depending on buildup, on top of the standard clean.

“Should I clean the sump at the same time as the roof tank?” Yes, it's more efficient and stops the sump re-dirtying the clean roof tank. Doing both together adds ₹1,500-2,500 for the sump depending on its size.
