In Yamuna Vihar, where one Sintex tank per stairwell feeds four to six flats across the C and B blocks, the plastic wall lets in enough light to turn the water green. KaamGenie cleans it gently and hygienic, with before and after photos. From ₹699.
Yamuna Vihar is one of trans-Yamuna’s largest planned blocks, a dense grid of DDA C-blocks and plot houses off the Wazirabad Road. The supply is a working mix of DJB pipeline and private borewell, and the riverside humidity here pushes both scaling and algae faster than in drier parts of the city. Almost every building keeps a small Sintex or plastic overhead tank, usually one per stairwell feeding several flats. That translucent plastic sits in open sun on the roof, so light passes straight through the walls and warms the water inside, which is exactly what algae and a slimy biofilm need to bloom. The borewell share adds hard-water scale on the plastic floor, and the algae film then grips that rough deposit. Residents here usually notice cloudy, off-smelling water first during the monsoon, when the humidity is at its worst.
KaamGenie cleans Sintex and plastic tanks across Yamuna Vihar’s blocks and plot houses. We check the tank and lid, drain it fully, scoop out the slimy settled layer by hand, wet-vacuum the base, then jet-wash at a pressure set safe for plastic so nothing cracks or gouges. We finish with an anti-bacterial disinfectant wash and send you before and after photos. If your building also needs an underground sump or an RCC tank done, see our full water tank cleaning in Yamuna Vihar. This page focuses specifically on Sintex and plastic tanks.
A Sintex tank on an exposed Yamuna Vihar rooftop takes full sun through the day. Light passes through the translucent wall and warms the water, and warmth plus light is what feeds algae and biofilm. A concrete tank stays dark and clear far longer, so the same DJB-and-borewell water that looks fine in an RCC tank turns a plastic tank green and slippery within a few weeks. The riverside humidity across this belt only speeds that up, which is why residents here see the film return sooner than they expect.
The second issue is the borewell that most Yamuna Vihar blocks fall back on when the DJB line is short. It runs hard, leaving a chalky scale on the plastic base and around the outlet, and the algae then clings to that rough surface. Because one tank often serves four to six flats up a single stairwell, it fills and drains many times a day, stirring sediment and pulling rooftop dust in through worn lids. Left between cleanings, that mix coats the interior walls quickly and taints the first draw each morning.
No travel charge anywhere in Yamuna Vihar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Do you clean Sintex tanks in the Yamuna Vihar C blocks?” Yes. The C-block grid off Wazirabad Road is one of our regular Yamuna Vihar rounds, and we cover the DDA flats and the plot houses alike. Whether it is one 1000L Sintex on a stairwell roof or several tanks across a whole building, our crew reaches you the same way, with plastic-safe cleaning throughout.
“What does it cost to clean a Sintex tank in Yamuna Vihar?” A Sintex tank up to 500 litres starts at ₹699, and a standard 1000L tank is ₹899. A larger 1500 to 2000 litre tank is ₹1,299 to ₹1,499. Because most buildings here run one tank per stairwell shared across flats, we give a bulk rate on four or more tanks, so a whole-building booking works out cheaper per tank.
“Can you do the whole building in one visit?” Yes, and in Yamuna Vihar that is usually the sensible booking. Since one Sintex often feeds several flats up a stairwell, we clean all the tanks in a building in a single coordinated visit and split the bulk rate across the flats, which is fairer than each family calling separately.
“Why does my plastic tank here go green even on DJB water?” Because algae feed on light and warmth, not only on dirty water. The translucent Sintex wall lets sunlight into the tank and the water warms up, so even clean DJB supply grows a film on the walls. Yamuna Vihar’s riverside humidity makes that worse, so plastic tanks green up faster here than in drier colonies.
“Will jet-washing crack an old Sintex tank?” No. We set the jet pressure specifically for plastic, so it lifts scale and biofilm without gouging or cracking the wall, and we scrub stubborn patches with soft pads rather than wire brushes. Wire brushes leave micro-scratches that algae settle into faster, so we avoid them on every Sintex tank in Yamuna Vihar.
