Which Chemicals Are Used for Tank Cleaning?

Keshavpuram’s quirk comes from the Lawrence Road industrial area next door: flour and food-unit dust that lands in tanks as ready-made nutrition for algae. In a translucent plastic tank in full sun, that is a bloom waiting to happen. KaamGenie resets it. From ₹699.
Keshavpuram is a DDA colony on the Red Line between Ashok Vihar and Lawrence Road — flats in lettered blocks sharing stairwell RCC tanks, plotted lanes toward Tri Nagar running per-floor plastic on their rebuilds. Its water-storage quirk blows in from the Lawrence Road industrial area’s flour and food-processing units: a fine organic dust that settles across the colony’s roofs. In an RCC tank that dust merely dirties the water. In a translucent plastic tank — light streaming through the wall, water warming in the sun — it acts as a nutrient feed, and algae respond the way anything responds to being fed.
KaamGenie cleans the plastic tanks across Keshavpuram’s blocks and plotted lanes — drain, wet-vacuum the green-tinged sediment, plastic-safe jet wash, soft-pad scrub of the bloom off the walls, then a food-grade disinfectant rinse with photos and a dated certificate. For the DDA blocks’ stairwell RCC tanks or a coordinated visit, our main water tank cleaning in Keshavpuram page covers everything; this page is specifically about the Sintex and plastic tanks.
Algae need three things: light, warmth and nutrients. A translucent tank in Delhi sun supplies the first two everywhere — what varies by colony is the third, and Keshavpuram’s airborne share of flour and organic fines from the Lawrence Road units supplies it generously. The result is blooms that outpace the neighbouring colonies’: tanks that green in weeks where the same tank in Ashok Vihar would take a season, and a slippery wall film that regrows fast if any of it survives the clean. Thorough wall-scrubbing, not just draining, is the difference here.
The colony’s split building stock decides who feels it. The DDA blocks’ shared stairwell tanks are RCC and stay dark inside; it is the plotted rebuilds toward Tri Nagar and the residents’ terrace add-ons — translucent, sun-exposed, often under-lidded — that catch the full effect. For those we recommend six-monthly cleans with particular attention to lid seating, because in this colony the lid is not just keeping out dirt; it is cutting off the food supply.
No travel charge anywhere in Keshavpuram. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our tank greens up within a couple of months of cleaning. Why so fast?” Almost certainly the Lawrence Road factor — organic dust from the flour and food units feeds algae that light through your translucent tank wall is already growing. Two fixes together: a thorough soft-pad scrub so no seed film survives the clean, and a properly seating lid to cut off the nutrient supply. Then six-monthly maintenance holds it.
“Is algae in the tank actually harmful?” Household algae are mostly a taste, smell and slime problem rather than a poison — but the biofilm they anchor harbours bacteria, and that is a real hygiene issue. Either way nobody wants green water. The clean removes film and biofilm together and finishes with a food-grade disinfectant rinse.
“What does it cost in Keshavpuram?” ₹699 for plastic tanks up to 500 litres, ₹899 for 501-1,000 litres, including the full wall scrub, wet-vacuum, disinfectant rinse, photos and dated certificate. Plotted-lane rebuilds with several floor tanks get a combined quote for one visit, split between owners however the building likes.
“Do you clean the shared tanks in the DDA blocks too?” The stairwell tanks in the lettered blocks are mostly RCC and fall under our main Keshavpuram service — we handle those with the block’s residents or RWA. This plastic-tank service covers your own terrace add-on or a rebuild’s floor tanks. One call to 95603 66362 sorts which crew you need.
“Can you come the same day near Keshav Puram metro?” Usually — call before 10 AM and the northwest round can generally fit Keshavpuram in the same day, metro side or Tri Nagar side. If the tank has visibly greened, mention it and we allow the extra scrubbing time in the slot.
