Model Town was laid out as a kothi colony long before the plastic tank arrived, yet today a Sintex loft or terrace tank sits above almost every bungalow and builder floor here. KaamGenie cleans those plastic tanks gently, hygienically and with before-and-after photos. From ₹699.
Walk the wide plots of Model Town’s three phases and you find the same arrangement repeated: DJB water drops into an underground sump, a pump lifts it to an overhead Sintex tank, and many homes keep a second smaller plastic loft tank for the top floor. Because that water sits and warms inside a translucent shell, sunlight passes straight through the plastic wall and feeds a green algae film that a concrete tank would have kept in the dark. The secondary loft tanks are the worst offenders here, small, rarely opened and forgotten for years at a stretch. Model Town’s piped supply is fairly clean, but even clean water grows biofilm once light and warmth reach it. Add the fine silt that settles twice, once in the sump and again on the roof, and the plastic walls go slimy well before anyone thinks to check. In a family bungalow that only watches the tap, the lid on a Sintex loft tank can stay shut for a decade.
KaamGenie treats Sintex and plastic tanks the plastic-safe way: we open and check the tank and its lid, drain it down, scoop out the slimy settled layer by hand, wet-vacuum the residue, then jet-wash at a pressure set for plastic and follow with an anti-bacterial disinfectant wash, sending you before-and-after photos at the end. If your bungalow also needs the underground sump or an RCC tank seen to, our full water tank cleaning in Model Town covers those as well. On this page the focus is Sintex and plastic tanks only.
A Sintex tank on an open Model Town rooftop takes direct sun through most of the day, and its translucent plastic wall lets that light straight into the water. Warmth and light together are exactly what algae and slimy biofilm feed on, so a plastic tank greens up while the concrete tank on the next plot stays clear. The small loft tanks that feed upper floors sit even more exposed and hold less water, so they warm faster and film over sooner than the main overhead tank below them.
The second issue is Model Town’s sump-and-overhead setup, where water settles in two places and drops sediment in both. That soft layer on the plastic floor gives the algae a rough footing to cling to, and because the loft tank in particular is out of sight, nobody disturbs the film as it spreads. Years pass between openings on many of these bungalows, so what starts as a faint green haze becomes a thick slimy coat that only a proper mechanical clean will lift.
No travel charge anywhere in Model Town. The final price is confirmed on the call before we come — it depends only on tank size and access.

“We have both an underground sump and a Sintex loft tank, will you do both?” Yes, and this is the usual Model Town job. The Sintex and plastic tanks are cleaned the plastic-safe way on this service, and if you want the underground sump done in the same visit we handle that too, so your whole line from sump to loft tank is clear in one round rather than two separate call-outs.
“How much for a 1000L Sintex on the roof?” A standard 1000L Sintex is ₹899, and a smaller loft tank up to 500 litres starts at ₹699. If yours is a larger 1000 to 2000 litre plastic tank the range is ₹1,299 to ₹1,499, and where a bungalow has several plastic tanks together we set a bulk per-tank rate so the whole house works out cheaper.
“Our loft tank is barely used, how often does it really need cleaning?” A little-used loft tank actually greens up faster, not slower, because the water sits still and warm in the sun for long stretches. Twice a year keeps a Model Town Sintex or loft tank clear, and if you have skipped it for years the first clean will lift a surprising amount of slimy film before that routine settles in.
“Do we need our pump running so the tank refills after cleaning?” It helps if your DJB fill or borewell can top the tank once we finish, so we time the visit around your supply hours where we can. We leave the Sintex tank clean and ready, and you simply let it refill on the next fill cycle without any special plumbing on your side.
“Is the water safe to use straight after the disinfectant wash?” Yes. We rinse the anti-bacterial wash out thoroughly before we close the tank, so once it refills the water is ready for normal household use. Nothing is left coating the plastic, and the before-and-after photos we send show the clean, rinsed inside so you can see exactly what the tank looks like when we hand it back.
