A decades-old riverside colony near Seelampur, Brahampuri keeps water in ageing plastic tanks whose walls have clouded and thinned over many summers by the Yamuna. Weathered plastic lets in more light and holds more film, and KaamGenie renews it from ₹699.
Brahampuri is a very dense old Trans-Yamuna colony pressed between Seelampur and the river, a tight weave of decades-old houses and rebuilt floors on narrow lanes. Supply is DJB with heavy borewell backup, and that borewell runs hard and often discoloured. Much of it is stored in ageing rooftop and plastic tanks that have weathered many years on these old roofs. Time has clouded and thinned the plastic, and long-settled, high-density living means many tanks carry years of sediment and scale. These are storage tanks well overdue a proper clean rather than a quick top-side rinse.
Our crew drains the tank, wet-vacuums the deep sediment, jet-washes at plastic-safe pressure and hand-scrubs the walls before a anti-bacterial disinfectant wash, and we point out any tank or lid too perished to keep. Dated before and after photos accompany the job. For the sump or a concrete tank on the same house, our full water tank cleaning in Brahampuri covers it. This page is specifically about Sintex and plastic tanks.
A plastic tank that has stood many summers by the Yamuna loses its opacity and its tight lid over time. Clouded, thinned walls actually let light diffuse into the water rather than block it, feeding algae, and the humid riverside air adds to the biofilm. So an old tank here fouls more readily than a newer one on the same water.
Decades of hard, sometimes discoloured borewell have layered scale and sediment deep in these long-settled tanks. That base rarely gets cleared in a dense colony where tanks are seldom opened, so it thickens year on year. When one is finally drained, the accumulated load is substantial, and the water clarity afterwards is usually a marked improvement.
No travel charge anywhere in Brahampuri. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our plastic tank is old and cloudy, does that make the water worse?” A weathered tank lets more light in and holds more biofilm, so yes it fouls faster. We clean it fully and tell you honestly if the walls have perished past safe use.
“The borewell water is sometimes discoloured, will cleaning fix it?” Cleaning removes the tank-side scale and sediment that add to the colour. If the discolouration comes from the borewell itself, we will say so and suggest a filter.
“The tank has years of buildup, can you really clear it?” Yes, we physically wet-vacuum and scrub out the deep sediment and scale rather than rinsing. Old, long-settled tanks like these show the biggest improvement afterwards.
“Should we replace an old tank or just clean it?” We clean it first and advise honestly. If the plastic has thinned or cracked badly, replacing it is worthwhile, but many old tanks clean up perfectly well.
“What does it cost for a standard old rooftop tank?” From ₹699 up to 500 litres and ₹899 for 1000L. Call 95603 66362 for larger or multiple tanks.
