South Extension mixes market showrooms with homes behind, and both run rooftop tanks — the last stop before every tap and washroom. KaamGenie cleans overhead tanks across Part I and Part II, food-grade and documented. From ₹699.
South Extension — Part I and Part II — is one of South Delhi’s premium market districts, with showrooms and offices along the main frontages and kothis and builder floors on the streets behind. Supply is DJB. Over the shops sit commercial rooftop tanks feeding retail washrooms and small eateries, while the residential lanes behind run family tanks. It is a genuinely mixed-use area with high hygiene expectations on both sides, and in every building the rooftop tank is the final point before the water reaches a tap.
KaamGenie cleans both the commercial and residential rooftop tanks of South Extension — draining, clearing the sludge, jet-washing the scale, hand-scrubbing the corners and inlets, then a food-grade disinfectant wash before refilling, with dated before-and-after photos and a certificate a showroom or eatery can keep for its hygiene file. We schedule around shop hours where needed. This page is part of our water tank cleaning in South Extension service and covers the overhead (rooftop) tanks specifically.
The commercial rooftop tanks over the South Ex showrooms and eateries serve steady footfall through the day, refilling often to keep washrooms and pantries running, and that frequent warm throughput lets biofilm settle on the walls faster than municipal chlorine can control. Where a tank feeds a small eatery, cooking exhaust and grease from the market also drift onto the terraces and can enter through imperfect lids. For any customer-facing business, that rooftop tank is a hygiene point that needs regular, documented cleaning.
On the residential side behind the markets, the kothi and builder-floor tanks share crowded terraces above busy commercial streets, so they collect heavy road and market dust that works in past worn lids. The mixed-use setting means tanks of very different loads sit close together — a lightly-used home tank that stagnates beside an overworked shop tank — and both build deposits, one from stillness and one from constant flow. Across South Ex, an annual clean suits the residential tanks and a more frequent schedule suits the commercial ones.
No travel charge anywhere in South Extension. The final price is confirmed on the call before we come — it depends only on tank size and access.

We reach every pocket of South Extension — and there’s no travel charge to any of them:
“Do you clean the commercial rooftop tanks over the showrooms in South Ex Part II?” Yes. We clean the rooftop tanks feeding showrooms, offices and small eateries across South Ex Part II and Part I, working around shop hours so a business is not left without water during trading. Each tank is jet-washed, scrubbed and disinfected food-grade, and we provide dated before-and-after photos and a certificate for your hygiene records.
“What does it cost to clean a rooftop tank in South Extension?” A residential 500-litre tank starts at ₹699 and a 1,000-litre tank is ₹899. Between 1,001 and 2,000 litres it is ₹1,299 to ₹1,499. The larger commercial tanks over the showrooms are quoted by capacity. Because South Ex mixes small home tanks and bigger commercial ones, we confirm the price once we know your tank’s litres.
“Can you clean my South Extension rooftop tank the same day?” Often, yes. Call the KaamGenie team on 95603 66362 and if the schedule allows we will reach you in South Ex the same day. A single residential tank takes about ninety minutes to two hours. For a showroom or eatery we can usually fit the clean into a quieter window the same day so trading is not interrupted.
“Why do South Extension rooftop tanks get dirty quickly?” The commercial tanks refill often to serve steady footfall, and that warm throughput lets biofilm settle fast, while market cooking exhaust drifts onto the terraces. The residential tanks behind share crowded roofs above busy streets and collect heavy road and market dust past worn lids. Mixed-use terraces mean both overworked and stagnant tanks, and both build deposits within months.
“We have a shared rooftop tank over our South Ex building — can you clean it around trading hours?” Yes. We survey the tank and your supply timing, then schedule the clean into a quiet window or after hours so the shops and offices keep water during trading. The tank is drained, jet-washed, scrubbed and disinfected food-grade, then refilled. You receive before-and-after photos and a dated certificate for the building’s hygiene and maintenance file.
