Sintex & plastic tank cleaning in Dwarka Sector 26 – plastic-safe algae and biofilm removal for CGHS societies on Dwarka’s western fringe. From ₹699.
Dwarka Sector 26 sits on the developing western fringe of Dwarka, a mix of institutional plots and a growing number of CGHS societies toward Najafgarh. New and older society blocks alike run Sintex or plastic overhead tanks over underground sumps, and the fringe’s open, low-shade layout means strong daylight reaches those translucent walls. That light drives algae growth on the inside faster than in any dark concrete tank. Sector 26 gets the Dwarka 50-50 supply of Sonia Vihar DJB and DDA borewell water, hard and high in TDS, which feeds the biofilm with minerals.
In a newly occupied CGHS block the plastic tank often gets little attention until the water shows a green tinge or a slick film on the wall. Our crew drains it, scoops the slimy sediment and soft jet washes at plastic-safe pressure so the walls are never cracked. To see everything we handle in the sector, our water tank cleaning in Dwarka Sector 26 page lists overhead tanks and sumps for plastic and concrete. We hand-scrub algae with soft pads, disinfect with a food-grade solution and finish with photos and a certificate.
Because Sector 26 is still developing, there is little shade from tall neighbouring blocks, so terrace tanks sit in direct daylight most of the day. That light passes through the translucent Sintex walls and gives algae the energy to bloom on the inside. The hard, high-TDS Dwarka water on the fringe carries plenty of minerals for it to feed on. Newer CGHS societies also tend to have gaps between move-ins, so tanks can hold slow-moving water, and slow water is where a slimy biofilm sets fastest.
Our cleaning is shaped around protecting the plastic. We drain the tank, scoop the settled slime, then use a soft jet wash at plastic-safe pressure that removes the film without gouging or cracking the wall. Algae is lifted with soft scrub pads instead of wire brushes, which would leave micro-scratches for the next bloom to take hold. A food-grade disinfectant follows, and we reseat the lid and check the overflow so daylight and dust cannot restart growth. Before-and-after photos and a certificate go to the society for its records.
No travel charge anywhere in Dwarka Sector 26. 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 26 — and there’s no travel charge to any of them:
“Our new Sector 26 CGHS block already has green water — how?” Even a new plastic tank greens quickly on Sector 26’s open western fringe because there is little shade and daylight reaches the translucent walls all day. That light feeds algae inside the tank, and the hard borewell water supplies the minerals. In a newly occupied block the water often sits still between move-ins, which helps biofilm set. A drain, soft scrub and food-grade disinfect clears it, and it stays clear for months.
“Will jet washing damage the plastic tank on our fringe block?” No — we run a soft jet wash at a plastic-safe pressure specifically so it cannot gouge or crack the wall. Sintex tanks on newer blocks are just as vulnerable to harsh pressure as older ones, so we keep the jet gentle and use soft pads for stubborn film. This lifts algae without scratching the surface, which is important because scratches invite the next bloom. Your tank comes out clean and undamaged.
“What is the charge for a 1000L Sintex tank in Sector 26?” A standard 1000L Sintex tank starts at ₹699, our entry price for overhead cleaning. The final figure depends on how heavy the algae and sediment are and whether you add the underground sump. We confirm it before any work begins so there are no surprises. Societies with several tanks across the block can ask about a combined rate.
“Why do we see black bits in water from our Sector 26 tank?” Black bits are usually flakes of aged biofilm plus fine sediment from the high-TDS fringe water. As the slimy layer builds inside a translucent tank it eventually sheds small dark pieces into the supply. Scooping the base and soft washing the walls removes the source, and the food-grade disinfectant slows any regrowth. We also check the lid and overflow so dust cannot add to it.
“Do you offer same-day cleaning toward the Najafgarh edge of Sector 26?” Yes, same-day slots are often available for Sector 26 even toward the Najafgarh edge, as it falls within our Dwarka coverage near Sectors 25 and 27. Call early and we can usually reach a CGHS terrace the same afternoon, subject to the day’s route. A single 1000L tank is a fast job once drained. We confirm the exact window when you book.
