Kardampuri is built up in 4 to 5 storey builder floors between Bhajanpura and Maujpur, and each one carries a plastic Sintex on the roof that a single tank has to feed to many rooms. A borewell-heavy hard-water mix leaves it chalky and full of fine sediment. KaamGenie cleans rooftop Sintex tanks here from ₹699.
The building type here shapes the problem. These are 4 to 5 storey builder floors packed close together, and the standard setup is one plastic Sintex on top supplying every floor below it. Because the supply is a borewell-heavy hard mix, the tank collects a chalky scale on its walls and a layer of fine sediment across the base, and because one tank serves so many rooms it is drawn down and refilled all day. The plastic being translucent, sunlight passes through and adds a green film on top of the scale. So the same tank is fighting hard-water deposits, settled grit and algae at once, which is a lot for a small rooftop tank to carry.
This service is for plastic Sintex and rooftop plastic tanks, the translucent ones that go chalky with scale and cloudy with fine sediment. Our crew drains the tank, scrubs the walls and base with soft pads and an anti-bacterial disinfectant wash, then refills, keeping wire brushes well away from the plastic. If the building also runs an underground sump or a masonry tank, the broader water tank cleaning in Kardampuri covers those. One call books the visit and a standard tank is done in about an hour.
The tank age and buildup are worth watching on these floors. The borewell-heavy hard mix leaves a chalky scale that roughens the inside of the plastic, and once a wall is rough it holds far more sediment and biofilm than a smooth one. Fine grit from the water settles into that rough scale and packs down at the base over the weeks. A clean strips the scale back so the wall is smooth again and the next round of buildup starts slower.
The one-tank-many-rooms setup keeps the muck moving. With every floor drawing from a single rooftop Sintex, the tank refills constantly and the settled grit never gets a long rest to stay put, so it keeps circulating in the water people use. The translucent walls add algae on top wherever sunlight reaches. We clean plastic-safe, jet pressure set for thin plastic and soft pads rather than wire brushes, so we clear the chalk, sediment and green without scratching the tank.
No travel charge anywhere in Kardampuri. The final price is confirmed on the call before we come — it depends only on tank size and access.

“One tank feeds our whole building. How does the pricing work?” You pay one cleaning charge for the tank, starting at ₹699 for up to 500 litres, and the floors usually split that single charge between them. If your building has four or more tanks in total we quote a bulk rate that lowers the per-tank cost.
“The inside of our tank feels chalky and rough. Can you fix that?” Yes. That chalky roughness is hard-water scale, and our scrub with an anti-bacterial disinfectant wash lifts it off so the wall is smooth again. A smooth wall holds far less sediment and algae, so the tank stays cleaner for longer.
“Will jet-washing be too harsh for the plastic tank?” No. The jet pressure is set specifically for plastic and we use soft pads, never wire brushes, so the walls are cleaned without being scratched or weakened. Scratches would only make the tank collect grime faster, which is why we avoid them.
“How often should the rooftop tank be cleaned here?” With one tank feeding several floors and refilling all day, every three to four months works well. The constant turnover keeps stirring scale and sediment back into the supply, so a shorter cycle keeps the water clean.
“How long will our water be off?” Around an hour for a normal rooftop Sintex, covering the drain, scrub, disinfectant wash and refill. We can schedule it for a quieter time of day so the building is not without water at peak hours.
