The long Karawal Nagar main road runs through one of north-east Delhi's biggest colony belts, where every rooftop carries plastic tanks fed by very hard borewell. KaamGenie de-scales and disinfects those overhead tanks that fur up within months. From ₹699.
Across the Wazirabad canal, Karawal Nagar spreads out as one of the largest unauthorised-colony belts in the city, an endless run of three and four storey builder floors strung along its busy main road. DJB barely reaches the interiors, so the colony lives almost entirely on private borewell, and that groundwater is very hard and noticeably iron-tinged. Nearly every roof holds two or three 500 to 1,000 litre plastic tanks, and on water this hard they scale up within a few months of a clean. With the floors heavily tenanted and turning over often, the tank cleaning schedule is a job nobody clearly owns.
We take on that neglected tank directly: drain it, break the hard scale off the plastic walls, bail out the iron sediment on the base, jet and scrub, then disinfect with a anti-bacterial wash and refill. On tanks that fur up this fast, the before-and-after photos make the build-up obvious, and the dated quality report helps whoever manages the let-out floors. This overhead page sits under the fuller water tank cleaning in Karawal Nagar service. Tell us how many tanks are on the roof and we will do them in one visit off the main road.
The borewell water is the whole story here. It is among the hardest and most iron-heavy in north-east Delhi, and on a warm plastic rooftop tank the minerals crust the walls and the iron settles as a rust-coloured layer remarkably quickly. A tank cleaned in spring can show visible scale again by the end of summer. Because the colony has no real DJB alternative, there is no softer supply to dilute that load, so the tanks take the full hardness every day.
The tenant churn makes it worse. Floors change hands often, and each incoming tenant assumes the tank is somebody else's responsibility, so it goes uncleaned across several occupancies. Meanwhile the iron sediment and biofilm keep building, discolouring the water and giving it a metallic edge, and flakes of scale foul the pump and valves the whole building shares. For a Karawal Nagar building on hard borewell, a clean every four to six months is realistic, because the water simply does not let a tank stay clear for a year.
No travel charge anywhere in Karawal Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our tank scales up again within months; is cleaning even worth it?” Yes, because the alternative is scale that keeps thickening and iron sediment building unchecked. On Karawal Nagar's very hard borewell we suggest cleaning every four to six months rather than yearly, which keeps the scale thin and easy to remove each time. Leaving it for a year lets the crust harden and the base fill, which is a bigger job and worse water in between.
“There are three tanks on our roof; do you do them all in one visit?” Yes. We clean all the rooftop tanks on a building in a single visit, which is quicker and cheaper than separate trips. Each is drained, de-scaled, scrubbed, disinfected and refilled in turn, and a bulk rate applies when we do several together. Tell us the number and sizes when you book.
“The water has a metallic taste and rusty tint; will a clean fix it?” A clean removes the iron sediment and scale that have settled in the tank, which reduces the tint and taste noticeably. If the borewell water is very high in iron at the source, the tank clean will not change that, and we will suggest an iron filter alongside. But a scaled, iron-lined tank always makes the problem worse, so clearing it is the first step.
“The floors are all rented; who should arrange the cleaning?” Any tenant can book it, but the building owner is the natural person since the rooftop tank is shared property. Where owners are absent, tenants often club together, book the clean and split the cost, and we send one report they can share. We are happy to coordinate with whoever holds the roof access.
“What does a standard rooftop plastic tank cost here?” A 500-litre plastic tank is ₹699 and a 1,000-litre one is ₹899. With two or three tanks common on Karawal Nagar roofs, booking them together brings a bulk discount. The heavy scaling does not change the rate, though it is the reason a shorter cleaning cycle pays off.
