Sintex & plastic tank cleaning in Dwarka Sector 3 — compact DDA-flat rooftops soft-washed free of green algae. From ₹699.
Dwarka Sector 3 is a compact DDA-flat neighbourhood of LIG and SFS blocks with pockets of independent builder floors woven between them. Almost every home draws from a rooftop Sintex or plastic overhead tank perched on the low-rise buildings. Packed close together with little shade, those tanks sit under the sun for most of the day. With daylight streaming through the translucent walls, algae and a slick biofilm settle in quickly.
A Sector 3 tank that has gone green inside is not a plumbing fault — it is algae feeding on the light through the plastic. Our crew drains and scoops the tank, soft-jets at plastic-safe pressure and hand-scrubs the film off with soft pads, finishing with a food-grade disinfectant. Our water tank cleaning in Dwarka Sector 3 is built for these tightly packed DDA rooftops and resale builder-floor tanks. Every clean closes with a reseated lid, an overflow check, photos and a certificate.
The defining feature of Sector 3 is density — buildings sit close, but the rooftop plastic tanks still catch full daylight. That light passing through the translucent Sintex walls lets algae grow inside, and there is rarely a shaded corner to slow it. Builder-floor tanks are often smaller and turn over faster, but they are also opened less often, so a biofilm creeps up unnoticed. The mineral-rich Dwarka supply gives that film plenty to cling to.
Because these tanks are compact and sometimes brittle from years of sun, gentle handling is essential. We drain fully, scoop the soft green sediment, then soft-jet at a pressure that cleans without gouging or cracking the plastic. Algae is scrubbed away with soft pads only, and a food-grade disinfectant finishes the inside. Reseating the lid tightly and checking the overflow blocks the light and airborne dust that would otherwise restart the bloom on a compact rooftop.
No travel charge anywhere in Dwarka Sector 3. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Dwarka Sector 3 — and there’s no travel charge to any of them:
“My Sector 3 DDA tank water looks green – is it safe?” Green water means algae is growing on the inside of your Sintex tank, which happens fast on Sector 3’s sunlit DDA rooftops. It is not water you should drink or cook with until the tank is cleaned, because the biofilm can carry bacteria. We drain, scoop, soft-scrub the walls and disinfect to food-grade standard so the green is gone. Reseating the lid keeps light out and slows any return.
“Will the jet wash crack my old builder-floor plastic tank?” No. Builder-floor tanks in Sector 3 are often older and a bit brittle, so we use a soft jet wash kept at plastic-safe pressure that will not crack or gouge them. We scrub algae with soft pads instead of wire brushes, protecting the smooth inner wall. The whole process is designed to clean thoroughly while being gentle on aged plastic. Your tank comes out clean and undamaged.
“What is the price for a 1000L plastic tank in Sector 3?” A 1000L Sintex or plastic tank starts at ₹699, covering the full drain, sediment scoop, soft jet wash, algae scrub, food-grade disinfectant, photos and certificate. Larger tanks or homes with more than one tank cost a little more. Most compact DDA LIG and SFS flats in Sector 3 fall within the standard rate. We confirm the price for your exact tank before any work begins.
“Why are there black bits in my water after a few weeks?” Those black bits are usually flakes of old biofilm and settled sediment that build up on the tank floor between cleans. In smaller builder-floor tanks the level drops often, stirring that layer into your supply. Our clean scoops out the sediment, soft-washes the base and disinfects so nothing remains to break off. You should see clear water again within a fill cycle or two.
“Do you offer same-day cleaning in Sector 3?” Yes, same-day slots are usually available across Sector 3’s DDA blocks and builder floors if you call in the morning. A single rooftop Sintex tank of around 1000L takes roughly an hour and a half from drain to certificate. Because buildings are close together here, our crew can often reach several homes in one route. Book early and we will aim to complete your tank the same day.
