Sintex & plastic tank cleaning in Dwarka Sector 20 — plastic-safe algae removal for the airport-side sector’s CGHS societies and new plots. From ₹699.
Dwarka Sector 20 is one of the newer-developed sectors toward the airport side, with CGHS societies alongside institutional and still-developing plots. Being newer, many homes and societies run large overhead tanks and underground sumps, and almost all are Sintex or plastic. Their translucent walls let daylight reach the stored water, so algae takes hold faster than it would in an opaque concrete tank. With Dwarka’s hard, high-TDS DJB-and-borewell supply, a green film can appear within a few weeks.
Across the sector’s societies and plots, residents choose us for a plastic-safe soft wash that clears algae without risking the tank wall. Our guide to water tank cleaning in Dwarka Sector 20 sets out the drain, scoop, soft-jet and disinfect steps clearly. We service large overhead tanks and underground sumps in a single visit. Every clean ends with dated photos and a sanitation certificate.
Sector 20’s newer construction means large-capacity Sintex tanks, and their translucent walls let sunlight straight through to the water. That light is exactly what algae needs, so overhead tanks on open, airport-side rooftops bloom green quickly in the sun. The bigger the tank, the more wall surface biofilm has to colonise once it starts. Add the sector’s hard, high-TDS water and its mineral scale, and slime builds up fast on floors and walls.
We tackle it with a plastic-safe soft wash tuned to these tanks. After draining, we hand-scoop the slimy sediment, then soft jet wash at a pressure that lifts algae without gouging or cracking the plastic. Soft pads clear clinging film across the large walls and floor, and a food-grade disinfectant sanitises everything before refill. We reseat the lid and check the overflow so light, dust and insects cannot restart the growth.
No travel charge anywhere in Dwarka Sector 20. 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 20 — and there’s no travel charge to any of them:
“Why does my large Sector 20 Sintex tank keep going green?” Big Sintex tanks in Sector 20 hold a lot of water behind translucent walls, and the daylight that reaches them feeds algae across a wide surface. On the open, airport-side rooftops the sun keeps them warm, so the green bloom returns without a proper clean and cover. We do a full soft wash and disinfection, then reseat the lid to block the light. On large tanks, a scheduled clean every few months keeps the water dependably clear.
“Is your jet wash safe for a newer plastic overhead tank?” Yes. We use a plastic-safe pressure that removes algae and biofilm without gouging, thinning or cracking the Sintex wall, so even a newer tank is treated gently. Stubborn film gets a soft-pad hand scrub rather than a wire brush that would score the surface. The tank comes out clean and undamaged, whether it is a rooftop overhead or an underground sump.
“What does a 1000L Sintex tank clean cost in Sector 20?” A 1000L Sintex or plastic tank starts at ₹699, including the drain, scoop, soft wash, disinfection, photos and certificate. Larger overhead tanks, which are common in this newer sector, and underground sumps are quoted on capacity before we begin. Booking the overhead tank and sump together is popular here and cheaper than two visits.
“Why are there black particles coming through the taps?” Black particles are usually settled borewell sediment mixed with biofilm flakes shed from the tank walls and floor. Dwarka’s hard water carries fine mineral silt that piles up in an uncleaned tank over time. We scoop out the sediment, soft-wash the walls, and disinfect so the water clears. A check of the lid and overflow afterwards helps keep new debris from entering.
“Can you come the same day to a Sector 20 CGHS society?” Yes, same-day service is usually available for the Sector 20 CGHS societies and plots if you book early. A single Sintex tank soft wash is quick, and even an overhead-plus-sump clean often fits into one visit. Larger or heavily fouled tanks just need a little extra time, and you always receive photos and a certificate at the end.
