Sintex & plastic tank cleaning in Dwarka Sector 1 — algae-scrubbed, soft-washed and disinfected without cracking the walls. From ₹699.
Dwarka Sector 1 is one of the sub-city’s earliest-settled pockets, sitting close to Dwarka Mor and Dashrathpuri with rows of DDA LIG and Janta flats alongside resale builder floors. Most low-rise blocks here still rely on rooftop Sintex and plastic overhead tanks that bake in the open sun. The Dwarka 50-50 supply mixes Sonia Vihar DJB water with DDA borewell draw, so tanks fill with hard, high-TDS water that leaves scale and feeds slime. Because the translucent plastic walls let sunlight straight through, green algae and a slippery biofilm take hold far faster than in a shaded concrete tank.
If your Sector 1 tank has turned the water faintly green or left a slimy ring at the water line, that is classic plastic-tank algae and it will keep coming back until the walls are hand-scrubbed clean. Our crew drains the tank, scoops the slimy sediment, soft-jets at a plastic-safe pressure and scrubs the algae film off with soft pads before a food-grade disinfectant. You can read the full scope of our water tank cleaning in Dwarka Sector 1 service, which finishes with a reseated lid and photos plus a certificate. Same clean covers rooftop tanks across the older DDA blocks near Dwarka Mor.
The single biggest reason plastic tanks in Sector 1 grow algae is light. Sintex and other translucent tanks let daylight pass through the walls, and once sunlight, warmth and the nutrients in hard borewell-mixed water meet, algae blooms within weeks. On the exposed rooftops of these low-rise DDA blocks there is no shade at all, so a tank cleaned in winter can green up fast by peak summer. The high TDS of the local Dwarka 50-50 supply only adds minerals that the biofilm clings to.
Cleaning plastic safely means never treating it like concrete. We drain the tank fully, scoop out the soft green sediment by hand, then use a soft jet wash at plastic-safe pressure so nothing gouges or cracks the walls. The algae film is lifted with soft scrub pads – never wire brushes that scratch grooves for new slime to root in – and finished with a food-grade disinfectant rinse. Finally we reseat the lid and check the overflow so stray light and dust can no longer feed a fresh bloom.
No travel charge anywhere in Dwarka Sector 1. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Why does my Sector 1 plastic tank keep turning the water green?” Green or faintly cloudy water is almost always algae growing on the inside walls of your Sintex tank. Because the plastic is translucent, sunlight passes straight through and feeds the algae, especially on the exposed rooftops around Dwarka Mor and the DDA blocks. Just draining the tank will not fix it — the film has to be hand-scrubbed off the walls. After our soft-pad scrub and food-grade disinfectant the water runs clear again, and reseating the lid keeps light out so it stays that way longer.
“Will your jet wash crack or damage my Sintex tank?” No. We use a soft jet wash set to a plastic-safe pressure, not the high blast used on concrete, so there is no gouging or cracking of the walls. The algae film is lifted with soft pads rather than wire brushes, which protects the smooth inner surface. Sintex and plastic tanks in Sector 1 are often years old and slightly brittle from sun exposure, so this gentle approach matters. Your tank comes out clean without a single new scratch or stress mark.
“What does it cost to clean a 1000L Sintex tank in Dwarka Sector 1?” A standard 1000L Sintex or plastic tank starts at ₹699, which covers draining, scooping sediment, the soft jet wash, algae scrubbing, food-grade disinfectant, photos and a certificate. Pricing scales up with larger tanks or if you have both a rooftop overhead tank and an underground sump. For the typical DDA LIG and Janta flats around Sector 1 the 1000L rate covers most homes. We confirm the exact figure before we start so there are no surprises.
“Where do the black or dark particles in my water come from?” Dark specks usually come from disintegrated old biofilm and settled sediment sitting at the bottom of the tank, sometimes mixed with fine mineral scale from the hard Dwarka 50-50 water. When the level drops, that layer stirs up and comes through your taps. We scoop the slimy sediment out fully, soft-wash the base and walls, then disinfect so nothing is left to shed. After cleaning you should see clear water again within a fill cycle or two.
“Can you clean my tank the same day in Sector 1?” Yes, same-day slots are usually available across Sector 1, Dwarka Mor and Dashrathpuri when you book early in the day. A single 1000L rooftop Sintex tank normally takes about an hour and a half from drain to disinfected and photographed. If you have an underground sump as well, we plan a little extra time. Call in the morning and we will try to fit you into the same day’s route.
