From the DDA Janta and LIG flats to the plotted kothis and small builder floors of Rohini Sector 2, we clean overhead tanks and sumps — same day where possible. Starting ₹699.
Sector 2 leans towards the smaller DDA Janta and LIG flats mixed with self-built plotted kothis on the inner lanes, so tank sizes here vary a lot — from tiny 500L poly tanks on a two-storey kothi to 2,000L shared tanks over a flat block. The DJB supply in these pockets is noticeably hard, and descaling is the single most common add-on we do in Sector 2 because float valves jam and heating elements fur up fast. The older Janta-flat tanks are often the original fittings and carry years of orange-brown sediment when we first open them. Kothi owners frequently have a ground sump plus an overhead tank, and the sump is what usually gets forgotten.
Bookings here are more owner-driven than RWA-driven because of all the independent kothis, so we run a lot of single-address same-day jobs. We keep a crew circulating through Sector 2 most mornings, which means a same-day slot is realistic if you call early.
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.
Because Sector 2's supply is hard, a very common call is a kothi where the overhead tank has visible white-grey scale and the ball valve keeps sticking. We drain and de-silt the tank, scrub the walls, then run a descaling treatment to strip the mineral crust before disinfecting and refilling. A standard 500-1,000L kothi overhead tank is ₹699-1,499 to clean, with the descaling add-on at ₹300-500 on top. For a 2,000L Janta-flat shared tank the band is ₹2,500-3,000. Doing the descale properly means the float and fittings behave for months afterwards.
Plenty of Sector 2 kothis have an underground sump feeding a rooftop tank via a pump, and the sump collects the heaviest sediment because everything settles there first. A combined sump-and-overhead clean runs ₹4,500-6,000 depending on sump size, and it is the job we most recommend for older kothis that have never had the sump touched. A sump on its own is ₹1,500-2,500. We seal and disinfect the sump lid properly on the way out so grit and insects stay out. Tenants moving into a rented kothi floor often book this before shifting in.
“My tank has white scale — can you remove it?” Yes, that is hard-water mineral scaling, very common in Sector 2. We add a descaling treatment for ₹300-500 on top of the normal clean, which frees up stuck float valves and clears the crust from the walls.
“Do you clean underground sumps as well as rooftop tanks?” We do both. A sump on its own is ₹1,500-2,500, and a combined sump-plus-overhead clean for a kothi is ₹4,500-6,000. The sump usually holds the most sediment, so it is worth doing together.
“Can you come to a single kothi the same day?” Yes — most of our Sector 2 work is single-address, and we keep a crew in the area, so a same-day slot is usually possible if you call in the morning.
