Overhead tank cleaning for the large kothis and diplomatic homes of Anand Niketan. On these elegant low-rise plots the big rooftop tank is the last stop before the tap — and being out of sight, it is rarely opened. From ₹699.
Anand Niketan is an elite, low-rise colony of large independent kothis and diplomatic residences near Chanakyapuri, laid out on generous plots in the A, B and C blocks. Homes here run big individual overhead tanks on the terrace, fed mostly on DJB supply and often paired with an underground sump. Because these are old, well-built houses where the water simply works, the rooftop tank tends to be forgotten for years — nobody climbs up to look until something goes wrong.
In an Anand Niketan kothi the rooftop tank is the final stage before the water reaches your kitchen and bathrooms, with no filter after it to catch what has settled. If you would also like the underground sump or the full property assessed, our water tank cleaning in Anand Niketan page covers everything. This page is specifically about the overhead (rooftop) tank — the large individual tank on your terrace.
The danger in Anand Niketan is complacency. These are quiet, low-occupancy homes where the tank is large and the water always flows, so years pass with the lid never lifted. But a big rooftop tank that is only half-drawn each day lets sediment settle undisturbed into a thick, compacted layer, and any biofilm on the walls quietly matures. An unopened kothi tank is often far dirtier inside than a busy builder-floor tank that at least gets churned and refilled.
Anand Niketan sits under mature trees and open sky, and on these spacious terraces the tanks collect blown dust, pollen and falling leaves through old or ill-fitting lids. Many of the original RCC and plastic tanks here are decades old, with worn seals and overflow vents that no longer keep light and insects out. On such a large tank the problem is invisible from below — the water looks fine at the tap while a settled sludge bed grows steadily until the tank is drained and scrubbed.
No travel charge anywhere in Anand Niketan. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Anand Niketan — and there’s no travel charge to any of them:
“Do you service the kothis in Anand Niketan A Block?” Yes. We clean large individual overhead tanks across A, B and C blocks and the plots towards Shanti Niketan. Our crew brings its own equipment up to the terrace and works cleanly around finished roofs and gardens, which matters on these well-kept Anand Niketan properties. A dated certificate follows on WhatsApp.
“What does cleaning a big kothi rooftop tank cost here?” It depends on the tank size. A tank up to 500 litres starts at ₹699, a 1,000-litre tank is ₹899, and the larger 1,001 to 2,000-litre rooftop tanks common in Anand Niketan kothis are ₹1,299 to ₹1,499. We measure on site and confirm the price before starting, with no surprises.
“Can you come the same day in Anand Niketan?” For a single kothi we can usually arrange a same-day or next-morning slot. Because Anand Niketan tanks are often larger and paired with a sump, many owners prefer to book a fixed time so the household water is off for the shortest possible window. Call 95603 66362 to arrange it.
“Our rooftop tank has not been opened in years – how dirty will it be?” Quite likely dirtier than you expect. In a low-use Anand Niketan home the tank is rarely fully drained, so sediment compacts into a firm layer at the base and biofilm matures on the walls. That is normal for a long-unopened kothi tank, and exactly what our full drain, sludge removal, jet-wash and disinfection is built to clear.
“Should an old concrete tank be treated differently from a plastic one?” Yes. Older RCC tanks in Anand Niketan can take a firmer jet on caked scale, while plastic and Sintex tanks get a gentler pressure and soft pads so they are not gouged. We check the material and the seals first, hand-scrub the corners and inlet, then reseat the lid so dust and light stay out afterwards.
