How Often Should You Clean Your Water Tank?

In Hazrat Nizamuddin, plastic and Sintex tanks serve both the upscale East kothis and the packed West lanes, and light through their walls turns them green fast. We clean them gently and food-grade. From ₹699.
Hazrat Nizamuddin splits into two very different worlds: the calm, upscale kothis of Nizamuddin East and the dense basti and flats of Nizamuddin West near the dargah and railway station. Both rely heavily on plastic and Sintex tanks — large individual ones on the East houses and older, smaller shared tanks crammed onto the West rooftops. Concrete is uncommon on these buildings, so plastic is the norm, and plastic is the material that lets in the light algae need.
The whole area runs on DJB, and the mix of quiet East tanks that sit still and busy West tanks that never rest both favour algae in their own way. If you also need an older shared tank or sump handled, our general water tank cleaning in Hazrat Nizamuddin page covers everything. This page is specifically about Sintex and plastic tanks and the green, slimy film they grow on both sides of Nizamuddin.
In Nizamuddin East, a large plastic tank often serves a small household, so the water sits still under the sun, and the light through the plastic walls feeds a slow green bloom. In Nizamuddin West the opposite happens: small tanks on crowded roofs warm up fast and refill constantly. Either way, plastic lets daylight in where concrete would keep it out, and warm, lit water is exactly what algae need. So both sides see a film form well before the next clean is due.
Sediment and dust finish the job. The DJB supply carries fine silt that settles on the plastic floor, and in the packed West lanes near the dargah, dust and grit drift in through lids that rarely seal on old buildings. In the East, tanks that sit unopened for months collect a soft sludge and a scale ring around the outlet. In both cases the settled matter feeds biofilm, leaving the slippery, gritty coating we regularly scrub from Nizamuddin tanks.
No travel charge anywhere in Hazrat Nizamuddin. 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 both Nizamuddin East and the Basti?” Yes. We cover all of Hazrat Nizamuddin, from the kothis of Nizamuddin East to the crowded lanes of the Basti and West flats near the dargah and railway station. Whether it is a large individual plastic tank or a small shared one, we can reach it and clean it properly.
“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. That includes draining, removing the slime and sediment, a plastic-safe wash, hand-scrubbing and a food-grade disinfectant, with photos on WhatsApp. In the West, where buildings share several tanks, we give a bulk discount on four or more.
“Can you clean my plastic tank the same day I call?” Usually yes. Nizamuddin is well within our regular routes, so same-day or next-morning visits are normally possible when you call early. A single Sintex tank takes about ninety minutes, and once it refills your home is back to normal supply the same day, with a photo record afterwards.
“Why does my Sintex tank in Nizamuddin keep going green?” In quiet Nizamuddin East the water sits still under sunlit plastic walls; in the busy West it stays warm and refills all day. Both give algae the light and warmth they need, because plastic lets daylight through where concrete would not. So the green, slimy film returns within weeks unless the tank walls are scrubbed rather than just rinsed.
“Is pressure washing safe for a plastic tank, and how do you remove algae without scratching it?” It is safe because we tune the pressure for plastic, so the Sintex walls are never cracked, even on the older tanks common in the Basti. Algae is removed with soft pads, not wire brushes, since wire scratches the plastic and lets biofilm return faster. A food-grade sanitiser then clears the last spores before the tank refills.
