Sintex & plastic tank cleaning in Dwarka Sector 9 – soft-wash, algae-free, food-grade safe for your metro-side high-rise. From ₹699.
Dwarka Sector 9 sits right on the Blue Line with a busy commercial frontage and a tight cluster of CGHS towers behind it. Most of those high-rises run rooftop overhead tanks fed from underground sumps, and a huge share of them are translucent Sintex or plastic units. Because light passes straight through those walls, algae and slimy biofilm bloom inside far faster than in an opaque concrete tank. Add Dwarka’s hard, high-TDS 50-50 Sonia Vihar and borewell supply and you get scale plus green film in a matter of weeks.
That is exactly why a plastic tank here needs a gentler touch than a masonry one — you cannot blast a Sintex shell at concrete pressures without risking hairline cracks. Our crews drain, scoop the slimy sediment, then soft-jet and hand-scrub the algae film with plastic-safe pads before a food-grade disinfectant. If you are comparing options across the sector, see our full water tank cleaning in Dwarka Sector 9 page for capacities and pricing. Every job ends with photos and a sanitation certificate for your society records.
The translucent walls of a Sintex or plastic tank are the root cause. Sunlight on a Sector 9 rooftop drives straight through the shell, and the algae inside simply photosynthesise and multiply. A poorly seated lid or a cracked overflow — common on the older CGHS blocks here — lets in extra light and airborne dust that feed the bloom even further. The result is the green tint and slimy inner walls residents notice within a month of the last clean.
Our process is built around not harming the plastic. We jet-wash at a plastic-safe pressure that lifts the biofilm without gouging or stressing the walls, then hand-scrub with soft pads rather than wire brushes that would score the surface. After a food-grade disinfectant rinse, we reseat the lid and check the overflow so light and dust can no longer feed new algae. You get a genuinely clean tank rather than one that looks better for a fortnight and greens up again.
No travel charge anywhere in Dwarka Sector 9. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Why does the water from my Sintex tank in Sector 9 look green or slimy?” Green or slimy water almost always means algae and biofilm growing on the inside walls of your translucent tank. In Sector 9 the rooftop tanks get strong sunlight, and light passing through the plastic feeds the algae rapidly. We drain the tank, scoop the slime, soft-scrub the walls and apply a food-grade disinfectant. Reseating the lid and sealing the overflow then keeps light and dust out so it does not bloom again.
“Will your jet wash crack or damage my plastic tank?” No — we deliberately run a lower, plastic-safe pressure on Sintex and plastic tanks, not the high pressure used on concrete. High-pressure blasting can gouge or hairline-crack a plastic shell, so we avoid it entirely. The stubborn algae film is lifted by hand-scrubbing with soft pads instead of wire brushes. Your tank comes out clean and structurally untouched.
“How much does it cost to clean a 1000L Sintex tank in Sector 9?” Cleaning starts from ₹699, and a standard 1000L Sintex tank sits at the lower end of our pricing. The final figure depends on how many tanks you have, their access on the rooftop, and the level of algae build-up. Sector 9 high-rise societies often bundle several towers together for a better per-tank rate. We confirm the price before we start, with no surprise additions.
“I keep seeing black or dark particles in my water — what are they?” Dark or black particles are usually detached biofilm flakes mixed with settled sediment and hard-water scale, which Dwarka’s high-TDS supply produces plenty of. As the algae layer ages it sloughs off in dark specks that show up at your tap. Our scoop-and-soft-wash process removes both the loose sediment and the film clinging to the walls. After a food-grade disinfectant the water runs clear again.
“Can you do same-day cleaning near Sector 9 market?” Yes, same-day service near Sector 9 market and the metro frontage is usually possible if you book early in the day. A single 1000L Sintex tank is a quick soft-wash job, so we can often fit it in the same slot. Larger CGHS societies with multiple towers may need a scheduled window. Call us and we will tell you the earliest realistic time.
