The Sintex tank on your Roop Nagar PG refills all day and its lid is usually ajar, so it greens faster than the family home this floor used to be. KaamGenie cleans it gently and hygienically. From ₹699.
Roop Nagar is a compact residential pocket next to Delhi University’s North Campus, and its older independent houses and floors have largely been converted into student PGs and rentals. The rooftop tanks feeding them are mostly Sintex or plastic, still on the DJB piped supply the family homes always had, but now serving far heavier occupancy. High student numbers mean those tanks refill repeatedly through the day, and their covers are often left ajar by tenants and plumbers. A translucent plastic tank open to the sky gets the worst of both: light through the walls warms the water and grows algae, while the open lid lets in dust and insects. The frequent turnover keeps sediment stirred so it never settles cleanly. What was once a lightly used family tank cleaned now and then is now a high-traffic one nobody owns, so it fouls on a tighter schedule than the building was ever designed for.
We clean these converted-home tanks the plastic-safe way: check the tank and lid, drain it, scoop the slimy layer off the bottom, wet-vacuum the residue, jet-wash at a pressure set for plastic and hand-scrub the algae with soft pads, then an anti-bacterial disinfectant wash and photos before and after. If a Roop Nagar building needs its sump or an RCC tank done too, our full water tank cleaning in Roop Nagar takes care of them. This page focuses on Sintex and plastic tanks.
The tank has not changed, but its workload has. A Sintex tank that once served a single family now feeds a full PG, refilling many times a day, and that churn keeps fine sediment suspended in the water instead of letting it settle. Every refill also draws rooftop dust in through the lid that tenants leave ajar. So a tank designed for gentle household use is now run hard and left open, and it fouls at a pace the family owners never had to think about.
The plastic itself sets the baseline. A translucent Sintex wall on a Roop Nagar roof passes sunlight into the water and warms it, feeding an algae film that a dark concrete tank would resist. Combine that with the open lids and constant refilling of a PG, and the film spreads across the whole inner wall quickly. With students coming and going and no one claiming the tank, it simply runs green until the water tastes of it, which is why these converted homes need a tighter cleaning schedule.
No travel charge anywhere in Roop Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“This floor used to be a family home, why does the tank need cleaning more often now?” Because the usage changed. As a family tank it was lightly used and cleaned occasionally; as a PG tank it refills all day and the lids stay open, so it fouls far faster. The same plastic tank now needs cleaning every three to four months to keep pace with the heavier occupancy it was never designed for.
“The tenants leave the lid open, does that speed things up?” It does. An open lid lets in dust, insects and extra sunlight, and every refill pulls that debris into the water. We seat the lid properly when we finish, and a covered tank stays clear noticeably longer, so it is worth keeping shut between our visits even in a busy PG.
“Can you clean without disturbing the student tenants?” Yes. All the work is on the roof at the tank, so tenants inside are not disturbed beyond a short break in supply while the tank drains and refills. We pick a quieter part of the day and work around your fill timing so the PG has water back before the evening.
“What will it cost for a standard rooftop Sintex here?” A standard 1000L Sintex is ₹899 and a 500 litre one is ₹699. Larger 1000 to 2000 litre tanks run ₹1,299 to ₹1,499. If the building has more than one plastic tank, a bulk per-tank rate applies, so a whole Roop Nagar PG works out cheaper per tank.
“How soon can you come once we notice the water is off?” Often the same or next day, as Roop Nagar sits in an area we cover regularly. Call 95603 66362 and we will try to route a crew to you quickly, timing the drain and refill around your supply hours so the tank is not left empty when the tenants need it.
