How Often Should You Clean Your Water Tank?

Most Madangir homes store water in a rooftop Sintex or plastic tank, and near Pushp Vihar those tanks pick up algae and sediment quickly. KaamGenie gives them a plastic-safe soft wash with food-grade disinfection. From ₹699.
Madangir is a resettlement colony and DDA-flat cluster near Pushp Vihar and Ambedkar Nagar, with tightly packed plotted houses and small apartment blocks. Water arrives on the DJB pipeline but is often boosted by borewells during shortfalls, which keeps hardness and TDS on the higher side. Nearly every home relies on a rooftop Sintex or plastic overhead tank plus underground storage, and because light passes through the plastic walls, algae and biofilm establish faster than in a concrete tank.
Intermittent supply and refilling from mixed sources leaves sediment and green growth in the tanks between cleanings, especially in the DDA blocks where tanks sit fully exposed on the roof. A plastic-safe annual clean stops that slime returning, and it fits alongside our broader water tank cleaning in Madangir covering both the sump and the overhead Sintex.
The translucent walls of a Sintex tank let sunlight through, and on Madangir’s open rooftops that light warms the water and feeds algae within weeks. When the DJB line runs low and the tank is topped up with borewell water, the extra minerals and any organic matter give the biofilm even more to grow on. A poorly seated lid finishes the recipe.
We drain the tank fully, scoop out the slimy sediment at the base, then soft jet-wash at a pressure that is safe for plastic so nothing gets gouged or cracked. The algae film is hand-scrubbed away with soft pads, we disinfect with a food-grade solution, and we reseat the lid and check the overflow so light and dust are shut out. Photos and a certificate come at the end.
No travel charge anywhere in Madangir. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of Madangir — and there’s no travel charge to any of them:
“Do you clean tanks in the Madangir DDA flats?” Yes, the DDA flats are one of our most-served pockets in Madangir. Shared rooftop Sintex tanks there sit fully exposed, so they grow algae fast and benefit from a yearly clean. We handle individual flat tanks and shared banks alike, and give each a photo record.
“The water from my plastic tank has green bits floating in it. Is that dangerous?” Those green bits are algae breaking off the biofilm on the tank walls, which is common in Madangir because the plastic lets light in. It is not water you want to drink or cook with untreated. We scrub the film off with soft pads and disinfect with a food-grade solution so the water runs clear again.
“Will the pressure washer damage my Sintex tank?” No. We deliberately use a soft jet at plastic-safe pressure and soft scrub pads rather than wire brushes, so your tank is not gouged, thinned or cracked. This matters especially for older Sintex tanks in the J Block area that may already be a few years old. The clean is thorough but gentle.
“How much for a 1000L Sintex tank in Madangir?” It starts from ₹699 for a standard Sintex or plastic overhead tank, and a 1000L unit sits in that band. If you want the underground sump cleaned in the same visit we bundle it at a combined rate. The price is fixed before we begin, with nothing hidden.
“Can you clean same day near Pushp Vihar?” Usually yes. We run crews across Madangir and the Pushp Vihar side daily, so same-day or next-day slots are normally available. Send your block and tank size and we will lock a time.
