Water Tank Cleaning Rules & Norms

Home › Water Tank Cleaning › Sintex / Plastic Tank Cleaning › Shiv Vihar
Stand on any Shiv Vihar roof near the Delhi-UP border and you see the same thing repeated across the skyline: tall packed buildings, each capped with a plastic Sintex tank baking in the open sun. Those tanks turn over constantly and grow green fast. KaamGenie cleans rooftop Sintex tanks across Shiv Vihar from ₹699.
The rooftops here are a field of plastic tanks. On this far edge of the North-East the builder floors run four and five storeys tall, tightly packed, and almost every one carries a shared Sintex on top. Sitting fully exposed, the translucent tanks let sunlight through their walls, and that light is exactly what a green algae film needs to spread on the inside. The hard borewell most buildings draw leaves a heavy scale on top of it, and because the tanks feed so many packed rooms they are refilling all day with barely any rest. What you see from the roof is a lot of tanks quietly going green and scaly at once.
Our service here is aimed squarely at plastic Sintex and rooftop plastic tanks, the exposed ones that bloom green and crust with scale. The crew drains the tank, scrubs the walls and floor with soft pads and finishes with an anti-bacterial disinfectant wash, then refills, no wire brushes anywhere near the plastic. If your building also has a ground sump or a concrete tank, the fuller water tank cleaning in Shiv Vihar takes care of those. One call books it, and a standard rooftop tank is usually done inside an hour.
The constant turnover is what keeps these tanks dirty. With tall buildings full of tenants drawing from one rooftop Sintex, the tank drains and refills many times a day, and every refill carries in fresh borewell scale and sediment. There is almost no still time for the muck to settle out and be left behind, so it stays circulating in the water. That kind of use needs a clean every three to four months to stay ahead of the buildup.
The exposure adds the green layer on top. Because the tanks sit unshaded and their plastic walls are translucent, sunlight passes right through and feeds algae and biofilm along the inside surface, which is why so many roofs here show the same green tint. Hard borewell scale gives that film a rough surface to grip. Our cleaning is plastic-safe, jet pressure set low for thin plastic and soft pads rather than wire brushes, so we clear the algae and scale without scratching or weakening the tank.
No travel charge anywhere in Shiv Vihar. The final price is confirmed on the call before we come — it depends only on tank size and access.

Every locality in Delhi stores different water, and that decides how fast a tank fouls. This is Shiv Vihar’s profile from The Delhi Water Index, built from our field observations across 250+ localities.

“Can you reach tanks on tall four and five storey buildings here?” Yes. Our crew carries the pump and equipment up to the rooftop by hand and works on top of the highest builder floors regularly. The height of the building is not an obstacle for cleaning a rooftop Sintex.
“Every roof around us has a green Sintex. Why does that happen?” It is the sunlight passing through the translucent plastic. Daylight reaches the water inside and feeds algae along the walls, so exposed plastic tanks across the whole area turn green together. Draining and scrubbing clears each one, though it will slowly come back in open sun.
“How often should a shared tank in a tall building be cleaned?” With so many tenants drawing from one tank and constant refills, we recommend every three to four months. High turnover keeps stirring scale and sediment back into the water, so a shorter cycle keeps it clean.
“Will the jet wash crack our plastic tank?” No. We set the jet pressure for plastic and use soft pads, not wire brushes, so the walls are cleaned without being scratched or stressed. The method is chosen to protect thin Sintex walls.
“Can we book a same-day slot?” Usually yes, subject to the day’s schedule. A single rooftop Sintex is quick to clean, so we can often fit one in the same day if you call in the morning.
