In Vasant Vihar’s A-to-F kothis and builder floors, old plastic rooftop tanks fed from big private sumps are often opened only once in years. KaamGenie cleans your Sintex tank gently and food-grade. From ₹699.
Vasant Vihar is an elite low-rise colony of large independent kothis, embassies and builder floors across A-to-F blocks. Supply is mostly DJB with private borewells, and each plot usually keeps a big individual underground sump feeding Sintex or plastic rooftop tanks — many of them old and rarely opened. On these spacious open terraces the translucent tank walls take full sun, so even in a quiet, low-density colony the water inside grows a green film and biofilm that nothing filters out before the tap.
KaamGenie cleans the plastic rooftop tanks in Vasant Vihar’s kothis and builder floors — draining, wet-vacuuming the sludge, soft jet-washing at a plastic-safe pressure and hand-scrubbing the algae with soft pads instead of wire brushes, then a food-grade disinfectant wash. If the large private sump underneath also needs doing, see our full water tank cleaning in Vasant Vihar. This page is specifically about Sintex and plastic tanks.
The plastic rooftop tanks on Vasant Vihar’s big kothis sit high and fully exposed on wide terraces. Light passes straight through the translucent Sintex walls and warms the water, and that light-and-warmth combination is precisely what algae and slimy biofilm need. Because the colony is low-rise and open, there is little shade over the tanks, so the sun works on them all day. Concrete tanks stay dark and clearer; plastic tanks here green up much sooner.
The bigger issue in Vasant Vihar is time. Many of these tanks are old and, on kothis where the sump does most of the storing, the rooftop plastic tank is opened only once in several years. Private borewell water leaves scale on the floor, dust settles through ageing lids, and the algae film thickens undisturbed. By the time a tank is finally opened, the biofilm is well established — which is exactly why we scrub gently rather than aggressively.
No travel charge anywhere in Vasant Vihar. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Vasant Vihar — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in B Block Vasant Vihar?” Yes. We cover all of Vasant Vihar’s A-to-F blocks and Poorvi Marg. On these kothis and builder floors we clean the plastic rooftop tank and, if the tank has not been opened in years, we take extra care lifting the settled biofilm gently so the old plastic wall is not stressed.
“How much to clean a 500-1000L Sintex tank in Vasant Vihar?” A Sintex tank up to 500 litres starts at ₹699 and a standard 1000L is ₹899. The larger plastic tanks common on Vasant Vihar kothis cost a little more by capacity, and where a plot has several tanks we give a bulk rate on four or more so the whole house is done economically in one visit.
“Can you clean my Vasant Vihar tank the same day?” Often yes. A morning call to 95603 66362 usually lets us route a crew to Vasant Vihar the same day. For an old tank that has not been opened in years we may suggest a slightly longer slot so we can clear the built-up biofilm properly, but we still work around your household’s water timing.
“Why does my old plastic tank in Vasant Vihar look so slimy inside?” Because it has had years of light through its translucent walls feeding algae, plus scale from borewell water and dust through an ageing lid, all undisturbed. On a kothi where the sump stores most of the water, the rooftop Sintex tank is rarely opened, so the slimy biofilm just keeps thickening until someone finally cleans it.
“Do you use wire brushes on these older Sintex tanks?” No. Old plastic is more brittle, and wire brushes would scratch and weaken it while leaving grooves that algae regrow into. We lift even years-old biofilm with a plastic-safe jet wash and soft pads, and a food-grade disinfectant finish, so your Vasant Vihar tank comes out clean without any damage to the wall.
