Sintex & plastic tank cleaning in Dwarka Sector 18 — plastic-safe algae removal for 18A’s towers near Venkateshwar Hospital and 18B’s DDA flats. From ₹699.
Dwarka Sector 18 splits into 18A, with upscale CGHS towers and the landmark Venkateshwar Hospital, and 18B, which is mostly DDA flats. Both halves lean on high-capacity overhead tanks backed by underground sumps, and the overwhelming majority are Sintex or plastic. Their translucent walls let daylight through to the stored water, so algae establishes far faster than it would in a concrete tank. Layer on Dwarka’s hard, high-TDS DJB-and-borewell water and a green biofilm can take hold within weeks.
From the 18A towers to the 18B blocks, residents book us for a soft wash that clears algae while keeping the plastic completely safe. Our guide to water tank cleaning in Dwarka Sector 18 explains the drain, scoop, soft-jet and disinfect method in full. We handle large overhead tanks and deep sumps in one coordinated visit. Every clean ends with dated photos and a sanitation certificate for your records.
Because Sintex and plastic walls are translucent, sunlight reaches the water and drives algae growth wherever the tank sits in daylight. In 18B the DDA rooftop overhead tanks are fully exposed and heat up fast, while in 18A the high-capacity tower tanks hold large volumes that give biofilm plenty of surface to spread across. Near a busy hospital-and-residential zone, water turnover and dust exposure only add to the load. The result is a slimy green film that returns without a proper clean.
Our plastic-safe process is built for exactly these tanks. We drain, hand-scoop the slimy sediment, then soft jet wash at a pressure tuned for plastic so algae lifts off without any gouging or cracking. Soft pads clear clinging film on the walls and floor, and a food-grade disinfectant sanitises everything before refill. Finally we reseat the lid and check the overflow so light, insects and dust cannot restart the algae cycle.
No travel charge anywhere in Dwarka Sector 18. 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 18 — and there’s no travel charge to any of them:
“Why does the tank in my 18A tower keep growing green algae?” The high-capacity Sintex tanks on 18A towers hold a lot of water behind translucent walls, and any daylight that reaches them feeds algae across a large surface. Warm weather speeds the bloom, so green returns if the tank is not cleaned and covered properly. We do a full soft wash and disinfection, then reseat the lid to cut off the light. For big tower tanks a scheduled clean every few months keeps the water reliably clear.
“Could a pressure wash crack our plastic sump or overhead tank?” No. We use a plastic-safe pressure specifically so the jet never gouges, thins or cracks Sintex or plastic. It removes algae and biofilm effectively while treating the tank body gently, and we hand-scrub stubborn spots with soft pads instead of wire. Whether it is a rooftop overhead tank or a deep underground sump, the cleaning is thorough and the tank stays sound.
“What is the price for a 1000L Sintex tank near Venkateshwar Hospital?” A 1000L Sintex or plastic tank in the Venkateshwar Hospital area of 18A starts at ₹699, covering drain, scoop, soft wash, disinfection, photos and a certificate. Larger overhead tanks and underground sumps are quoted on their capacity before we start. Many 18A households book the overhead tank and sump together, which is more economical than two separate visits.
“Why do I see black particles after the supply runs?” Black or dark particles are usually a blend of settled mineral sediment from Dwarka’s hard water and flakes of biofilm coming off the tank walls. Over time both accumulate on the floor of an uncleaned tank and get stirred into the flow. We scoop out the sediment, soft-wash away the biofilm and disinfect so the water clears. A proper lid and overflow check keeps new debris from getting in.
“Do you offer same-day cleaning in Sector 18B?” Yes, same-day slots are usually available for the Sector 18B DDA flats and the 18A towers when you call early. A single Sintex tank soft wash is fast, so an overhead-plus-sump clean often fits into one visit. Very heavy algae just needs a bit more scrubbing time, and you always receive photos and a certificate at the end.
