Sintex & plastic tank cleaning in Dwarka Sector 23 – soft-wash algae and slimy biofilm removal for CGHS towers and society sumps. From ₹699.
Dwarka Sector 23 is a settled CGHS residential pocket where society towers rise between institutional plots, and almost every block runs a translucent Sintex or plastic overhead tank with an underground sump below. Because the walls let daylight through, green algae and a slimy biofilm take hold far quicker here than in an opaque concrete tank. Sector 23 draws the usual Dwarka 50-50 mix of Sonia Vihar DJB supply and DDA borewell water, which is hard and high in TDS, so scale and sediment settle fast. That combination of light plus mineral-rich water is exactly what algae feeds on.
For a mid-rise CGHS block, a plastic tank left uncleaned for a year can turn the first pour of the morning faintly green or leave a slick film on the inner wall. Our crew drains the tank, scoops the slimy sediment, then soft jet washes at a plastic-safe pressure that lifts the film without gouging the surface. If you are comparing options across the pocket, our full water tank cleaning in Dwarka Sector 23 page covers overhead tanks and sumps for both concrete and plastic. Every job ends with a food-grade disinfectant wipe, photos and a certificate.
The core reason is light. A Sintex or plastic tank has translucent walls, so even a modest amount of daylight reaching the terrace passes through and gives algae the energy it needs to bloom. Add Dwarka’s hard, high-TDS borewell blend and you have both light and nutrients sitting inside the tank. In Sector 23’s CGHS towers, where a single tank feeds many flats, water can sit for hours between demand peaks, and still water is where biofilm sets fastest. Concrete tanks stay dark inside, which is why they green far more slowly.
Our process is built around not cracking that plastic. After draining and scooping the slimy layer, we use a soft jet wash tuned to plastic-safe pressure rather than the harsh blast used on RCC tanks. Algae film comes off with soft scrub pads, never wire brushes that leave micro-scratches for the next bloom to grip. We finish with a food-grade disinfectant, then reseat the lid and check the overflow so no gap lets light or dust feed fresh algae. You get before-and-after photos and a signed certificate for the society records.
No travel charge anywhere in Dwarka Sector 23. 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 23 — and there’s no travel charge to any of them:
“Why does the water from my Sector 23 Sintex tank look faintly green?” A greenish tint is almost always algae growing on the inner walls of the translucent tank. Daylight passing through the plastic feeds it, and Dwarka’s hard borewell water gives it the minerals to spread. In a Sector 23 CGHS block where one tank serves many flats, the water can sit long enough for a slimy film to build. A full drain, soft scrub and food-grade disinfect clears it and the water runs clear again.
“Will a jet wash crack or damage my plastic overhead tank?” No — we deliberately run the soft jet wash at a plastic-safe pressure, not the high blast used on concrete tanks. Sintex walls are thinner and can gouge or craze under harsh pressure, so we pair a gentler jet with soft scrub pads instead of wire brushes. This lifts the algae film without scoring the surface, which matters because scratches give the next bloom something to grip. Your tank is left clean and structurally untouched.
“What does it cost to clean a 1000L Sintex tank in Sector 23?” Cleaning starts at ₹699, and a standard 1000L Sintex tank on a CGHS terrace usually falls in the entry band. The exact price depends on how heavy the algae and sediment are and whether an underground sump is included. We confirm the figure before we start, so there is no surprise on the bill. Society blocks with several tanks can ask about a combined rate.
“There are tiny black particles in my tank water — what are they?” Dark or black specks are usually a mix of detached biofilm and settled sediment from the hard, high-TDS water Sector 23 receives. As the slimy layer ages it flakes off in small dark pieces that come through the tap. Scooping the sediment and soft washing the walls removes the source, and the disinfectant stops it reforming quickly. We also check the overflow and lid seal so dust cannot add to it.
“Can you clean my Sector 23 tank the same day I call?” Yes, same-day slots are often available for Sector 23 because it sits in our core Dwarka coverage near Sectors 22 and 24. If you call in the morning we can usually reach a CGHS terrace the same afternoon, subject to the crew’s route. A single 1000L Sintex tank is a quick job once drained. We confirm the time window when you book.
