How Often Should You Clean Your Water Tank?

If the water in your Kamla Nagar PG or builder floor has started tasting flat, the plastic Sintex tank on the roof is usually the reason. KaamGenie cleans it gently, hygienically and with photos. From ₹699.
Right beside Delhi University’s North Campus, Kamla Nagar packs converted PGs, hostels and student-rented builder floors above a constantly busy shopping market, and nearly every one keeps a Sintex or plastic overhead tank. These blocks are high-occupancy, so the tank fills and drains many times a day, and heavy student usage means the lid is often left loose or off entirely. A translucent plastic tank sitting open on a market rooftop gets a double dose of trouble: sunlight through the wall grows algae inside, while dust from the lanes below drifts in through the gap. The rapid refilling keeps sediment stirred so it never settles out cleanly. On DJB piped supply the incoming water is decent, but none of that helps once the plastic walls are filmed green and the covers left ajar. Landlords juggling several floors rarely climb up to check, so the tank is skipped far longer than a family home would allow.
We clean these tanks the plastic-safe way, which the constant PG turnover here calls for: 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. For a whole building with a sump or an RCC tank as well, our full water tank cleaning in Kamla Nagar covers the lot. This page is about the Sintex and plastic tanks specifically.
Two things speed a Kamla Nagar plastic tank along. First, it sits in open sun on a market rooftop, and the translucent Sintex wall lets that light straight into the water, warming it and feeding algae the way a dark concrete tank never would. Second, PG lids are routinely left loose, so besides light through the walls the tank also takes airborne dust and the odd insect straight from the crowded lanes below, giving the film even more to grow on.
The occupancy pattern makes it worse. A tank feeding a full PG block empties and refills several times a day, and that churn keeps fine sediment suspended instead of letting it settle where it could at least be ignored. Every refill also draws fresh dust in through the open cover. So the film spreads across the whole inner wall fast, and with no single caretaker on these transient-tenant floors, the tank is simply left to it until the water turns visibly off.
No travel charge anywhere in Kamla Nagar. The final price is confirmed on the call before we come — it depends only on tank size and access.

“The PG lids are always left open, is that really the problem?” It is a big part of it. An open lid on a Kamla Nagar rooftop lets in dust, insects and even more sunlight, and every refill pulls that debris deeper into the tank. When we finish we make sure the lid seats properly, because a tank that stays covered between our visits films over far more slowly than one left open to the market air.
“We run a PG with tenants coming and going, can you clean without disturbing rooms?” Yes. The work is all 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 fit the visit to a quieter part of the day and around your fill timing, so the PG has water back for the evening rush.
“How often should a busy student-block Sintex tank be cleaned?” More often than a family home, because the constant refilling and open lids keep it dirty. For a full PG or hostel block we suggest every three to four months, which stops the algae film and stirred sediment from ever building to the point where the water tastes flat or smells.
“What will it cost for the tank on a builder floor here?” A standard 1000L Sintex is ₹899 and a smaller 500 litre one is ₹699. Larger 1000 to 2000 litre tanks run ₹1,299 to ₹1,499, and if your building has a plastic tank per floor we give a bulk per-tank rate so cleaning the whole block costs less than booking each separately.
“Can you come the same day if the water has already turned bad?” Often yes, since Kamla Nagar is a compact area we work regularly. Call 95603 66362 in the morning and we will try to route a crew to you the same day, and if the slots are full we fix the next day around your supply timing so the tank is not empty when your tenants need it.
