Wall-to-wall three and four storey builder floors line the narrow interior lanes of Mandawali Fazalpur, almost all fed by hard, iron-tinged borewell. Every roof carries several small plastic tanks that scale fast, and KaamGenie descales them from ₹699.
Mandawali Fazalpur is a dense unauthorised-regularised belt between Patparganj and Mandawali, built up floor upon floor on lanes barely wide enough for a scooter. DJB reaches only the main roads, so the interior runs overwhelmingly on private borewell, and that groundwater is hard and often iron-tinged. Each roof stacks multiple small plastic tanks, one for each rental floor, and they scale from the inside within months. With most floors let out, the tanks tend to go uncleaned for long stretches.
Our crew drains each tank, lifts out the grit, jet-washes the scale and iron film, hand-scrubs the corners and disinfects with a hygienic rinse, leaving before-and-after photos. This page is for rooftop tanks; the full area service is at water tank cleaning in Mandawali Fazalpur.
The borewell under Mandawali carries both hardness and dissolved iron, a harder combination on a tank than plain hard water. The minerals crust the walls white while the iron settles as an orange-brown film that stains everything downstream. On a roof with three or four small tanks, that fouling repeats across every unit, and the tighter the building, the less anyone climbs up to check.
Inside a neglected tank you get white scale on the walls, an orange sediment on the floor and a biofilm in the still corners, which together stain taps and buckets and leave a metallic taste. Because the interior lanes are so tight and the floors mostly rented, tanks can sit years unopened. A landlord booking the whole roof for a descale every six months is what keeps the water usable.
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.

“Our water leaves orange stains on the taps. Will cleaning fix it?” The orange is iron from the borewell settling in the tank and on the fittings. Cleaning removes the iron film and sediment from the tank, so the staining eases at the source; plastic that has held iron for years may keep a faint tint, but the surface comes away clean.
“Our small roof has four tanks. Can the crew manage in the narrow lane?” Yes, our crews work these interior lanes routinely and carry equipment up by hand where a vehicle cannot reach. We clean all the roof's tanks in one visit, each billed at its size, and sequence them so water stays available.
“How often on iron-heavy borewell?” Every six months at least, and heavy-occupancy buildings do better on every four. Iron and hardness rebuild quickly here, so a regular descale stops the film thickening and the stains worsening between visits.
“The owner does not live here. Can we still get it done?” Yes. Share the landlord's number or arrange it among the floors; we coordinate access with whoever is home and send photos and a quality report so an off-site owner can confirm the roof was covered.
“The water tastes metallic. Is the tank the cause?” Partly, an iron sediment and biofilm in the tank add to the metallic taste on top of the borewell itself. A full drain, scrub and disinfection removes the tank's contribution; we will show you what comes out so you can judge how overdue it was.
