In Sadiq Nagar, the plastic and Sintex tanks on the compact DDA flats and builder floors near Andrewsganj quietly grow algae through their sunlit walls. We clean them gently, food-grade and photo-documented. From ₹699.
Sadiq Nagar is a compact residential pocket of DDA flats and builder floors near Andrewsganj and South Extension. Water is stored in society overhead tanks and plot-level sumps, and on the rooftops those overhead tanks are almost always plastic or Sintex. In a tightly packed pocket like this, the buildings sit close together but the roofs are open to the sun, so the plastic tanks get plenty of daylight. That sunlight through plastic walls is precisely what lets algae take hold inside a tank here.
The pocket runs on DJB supply, and the fine silt it carries settles on plastic floors between cleans. If your block also needs its underground sump done or a fuller service, our general water tank cleaning in Sadiq Nagar page covers it. This page is specifically about Sintex and plastic tanks — the rooftop overhead tanks in this compact pocket that go green and slimy first.
The plastic overhead tanks on Sadiq Nagar rooftops sit open to the sun despite the tight building layout, and light through their walls is exactly what green algae feed on. A shared society tank feeding several flats stays lukewarm from steady use and the rooftop heat, extending the growing hours. A concrete tank would stay dark and cool inside and slow a bloom, but Sintex and plastic light up and warm through, so a green film spreads across the walls sooner than residents expect after a clean.
Sediment and dust finish it. The DJB supply carries a fine silt that settles on the plastic floor, and around the outlet a scale ring traps slime. In a compact pocket close to busy roads, dust drifts in through lids that no longer seal on older society tanks. Because a shared tank is refilled several times a day for a full block, the silt never settles out to be removed, so the sediment and biofilm build into a slippery, gritty layer between cleans.
No travel charge anywhere in Sadiq Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Sadiq Nagar — and there’s no travel charge to any of them:
“Do you clean Sintex tanks in the Sadiq Nagar DDA flats?” Yes. We cover all of Sadiq Nagar, including the DDA flats, the area near Sadiq Nagar market and the builder floors towards Andrewsganj and South Extension. Whether it is a single flat’s plastic tank or a shared society tank on the roof, we can usually arrange a visit within the same week.
“What does it cost to clean a 500 to 1000 litre Sintex tank here?” A plastic tank up to 500 litres starts at ₹699, and a standard 1000 litre Sintex tank is ₹899. The price covers draining, sediment and slime removal, a plastic-safe jet wash, hand-scrubbing and a food-grade disinfectant, with photos afterwards. A society with several tanks on one roof gets a bulk discount on four or more done together.
“Can you clean my plastic tank the same day I call?” Usually yes. Sadiq Nagar is central to our South Delhi routes, so same-day or next-day visits are normally possible if you call in the morning. One standard Sintex tank takes about ninety minutes, and once it refills the flats are back to normal supply the same day.
“Why does my Sintex tank in Sadiq Nagar turn green so fast?” Sadiq Nagar tanks are plastic and sit open to the sun even in this compact pocket, so light passes through the walls to feed algae. A shared society tank stays warm and refills several times a day, which keeps the film supplied. Rinsing does not remove it, so the green, slimy layer returns within weeks unless the walls are scrubbed.
“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” It is safe when the pressure is set for plastic, which is exactly what we do, so the Sintex walls are never gouged or cracked. Algae is removed with soft pads instead of wire brushes, because wire leaves scratches that let biofilm grip and regrow faster. A food-grade sanitiser then clears the last spores before the tank refills.
