On the narrow lanes between Patparganj and Mandawali, three and four storey builder floors run almost entirely on hard, iron-tinged borewell, and the multiple small plastic tanks on each roof stain and scale fast. KaamGenie drains, scrubs and disinfects them, from ₹699.
Mandawali Fazalpur is a dense unauthorised-regularised belt, wall-to-wall three and four storey builder floors packed onto narrow lanes between Patparganj and Mandawali. Water is overwhelmingly private borewell, hard and often iron-tinged, with the DJB pipeline reaching only the main roads. Every roof carries several small plastic tanks, one per floor or landlord, and the iron in the water leaves a brown tinge as well as scale on the plastic. With most floors rented, those tanks go uncleaned for long stretches, so grit and biofilm build inside unseen.
We drain each tank, wet-vacuum the iron-stained sludge off the base, scrub the plastic walls with soft pads to lift the tinge and biofilm, then finish with a anti-bacterial disinfectant wash and photographs for the record. Buildings with an underground store as well add it under our full water tank cleaning in Mandawali Fazalpur. On this page the work is the small rooftop Sintex and plastic tanks that crowd every roof.
The borewell here does two things to a plastic tank. Being hard, it lays a scale on the walls and floor; being iron-tinged, it stains the plastic a brownish shade and leaves a rusty sediment. On top of that, the translucent Sintex wall lets daylight warm the water, so an algal film grows over the stained, scaled surface. A concrete tank hides none of this because it never lets the light in to begin with.
With several small tanks per roof, each feeding a single floor, none holds much water and all are drawn down and refilled hard, keeping the sediment stirred. Residents see it as discoloured or gritty water and a metallic taste after the tank sits. Because the floors are rented and no one owns the tank, the iron sediment and biofilm simply accumulate, and only a physical drain-and-scrub clears the stain and the film off the plastic.
No travel charge anywhere in Mandawali Fazalpur. The final price is confirmed on the call before we come — it depends only on tank size and access.

“My tank water looks brownish, is the tank at fault or the borewell?” Both play a part. The iron in the borewell tinges the water and leaves a rusty sediment, and that sediment then coats the plastic tank and stains it. Cleaning the tank removes the settled iron and the stain, though very iron-heavy borewell may need a filter at source as well.
“There are separate tanks for each floor, do you do them all?” Yes. We clean each rooftop tank on a building in turn during one visit and photograph each, and we quote a per-tank rate when there are several. That way every floor's tank is done rather than just the one that complained.
“What does one small floor tank cost to clean?” For the small single-floor tanks common here, up to 500 litres, the price starts at ₹699. A whole building's worth of tanks done together is quoted at a lower per-tank rate.
“Can you get equipment into these narrow lanes?” Yes. We work these tight regularised lanes regularly and bring gear sized for cramped builder-floor roofs, so the lane width is rarely an obstacle. Access to the roof is arranged with whoever holds the key.
“How often should an iron-water plastic tank be cleaned?” With hard, iron-tinged water staining and silting the tank quickly, quarterly is the safer cadence and twice a year the minimum. The faster the tank discolours, the more a fixed schedule pays off over waiting for the water to look off.
