Which Chemicals Are Used for Tank Cleaning?

Uttam Nagar roofs rarely carry one plastic tank — most builder floors run two or three, all scaling on the same hard borewell water. KaamGenie cleans every Sintex and plastic tank on the roof in one visit, plastic-safe and food-grade. From ₹699.
Uttam Nagar stretches along the Blue Line’s tail either side of Najafgarh Road — endless 3-4 storey builder floors and rental blocks from Uttam Nagar East to Uttam Nagar West and deep into Om Vihar and Vikas Nagar. Water here is overwhelmingly private borewell, very hard and tinged with iron, because DJB lines reach little beyond the metro-road spine. Every roof carries multiple 500-1000L plastic tanks, and on this water they grow a white mineral crust inside within months, faster than almost anywhere else in Delhi.
KaamGenie cleans Sintex and plastic tanks across the whole Uttam Nagar belt — draining, wet-vacuuming the silt, soft jet-washing at a plastic-safe pressure that lifts borewell scale without cracking the wall, hand-scrubbing with soft pads, then a food-grade disinfectant wash with photos and a dated certificate. Because most roofs here have several tanks, we quote a per-tank rate for the whole roof. For RCC tanks or the full service picture, see our page on water tank cleaning in Uttam Nagar; this one is specifically about plastic tanks.
Uttam Nagar’s borewell water is among the hardest in west Delhi, and a plastic tank shows it quickly. The minerals settle into the ribbed interior of a rotomoulded tank — those moulding ridges around the base trap scale that a casual rinse never reaches — while the iron content jams float valves and leaves rusty streaks down the translucent walls. Add full sun on an open builder-floor roof and algae grips the roughened plastic, something the same water never manages inside a dark concrete tank.
The other problem is ownership. With three or four rental floors sharing a roof and tenants changing every year, nobody in a typical Uttam Nagar building holds the cleaning schedule, so tanks go two or three years untouched while the crust thickens. Many older tanks are also UV-faded and chalky outside, which is exactly why we keep jet pressure plastic-safe and use soft pads — an aged Sintex wall scrubbed with a wire brush ends up scratched and greens up faster. On this water, a six-monthly clean per tank is realistic.
No travel charge anywhere in Uttam Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Can you clean all three plastic tanks on my Uttam Nagar roof in one visit?” Yes, that is the normal job here — most Uttam Nagar builder floors run two or three tanks on one roof. We drain and clean them one after another in a single visit, and for four or more tanks we give a per-tank bulk rate, so a full roof works out cheaper than booking each tank separately.
“What does a Sintex tank clean cost in Uttam Nagar?” A plastic tank up to 500 litres is ₹699, and a 501-1,000L tank is ₹899, including drain-down, wet-vacuuming, plastic-safe jet wash, food-grade disinfection and before-after photos. Uttam Nagar’s borewell scale can be heavy in a neglected tank, and we flag anything unusual before we start.
“Why is there white crust inside my plastic tank near Uttam Nagar East metro?” That crust is hardness scale from the borewell water almost every building off Najafgarh Road runs on. It builds along the moulding ribs at the base of the tank and around the outlet, and it gives algae a rough surface to grip. We soften and lift it with a plastic-safe jet and soft pads rather than chipping at the wall.
“We are tenants and the landlord never cleans the tank. Can we book directly?” Yes, tenants book us all the time in Uttam Nagar — you do not need the owner present, just roof access. We photograph the tank before and after and share the dated certificate, which most tenants pass to the landlord to sort out the cost between them.
“Can you come the same day in Uttam Nagar?” Usually yes. The belt from Uttam Nagar East to Om Vihar is one of our busiest routes, so if you call 95603 66362 before 10 AM we can generally slot a crew in the same day. Later calls go to the next morning, timed around your borewell pumping hours so you are not left without water.
