What’s Included in a Water Tank Cleaning Service?

Behind the hedges and long driveways of Civil Lines, a plastic Sintex tank quietly feeds the taps of these old bungalows and government kothis. KaamGenie cleans it gently, hygienically and with photos. From ₹699.
Civil Lines reads as a leafy, low-density heritage precinct, but the water story under its large roofs is the same as anywhere: piped DJB supply lifted from a big underground sump into an overhead tank, and on many buildings that overhead tank is a Sintex or plastic one. The generous capacities that suit these sprawling houses mean water turns over slowly, sitting for days in a translucent tank that lets daylight through. Light and standing warmth are all algae need, so a green film forms on the plastic walls even though the piped water arrives clear. The bigger the tank and the slower the household draws on it, the longer that film has to spread undisturbed. Many of these kothis have staff who never climb to the roof, so the tank goes unopened between long gaps. By the time the water carries a faint earthy smell, the inside of the plastic tank is already coated.
Our plastic-safe method suits these older buildings: we inspect the tank and lid first, drain the standing water, hand-scoop the slimy sediment off the floor, wet-vacuum what remains, jet-wash at a plastic-safe pressure that will not gouge the walls, and finish with an anti-bacterial disinfectant wash before photographing the result for you. Where a Civil Lines bungalow also runs a masonry sump or an RCC overhead tank, our full water tank cleaning in Civil Lines takes care of those. Here the focus stays on Sintex and plastic tanks.
The defining feature of Civil Lines water is how slowly it moves. A large Sintex tank on a lightly occupied bungalow can hold the same water for days, and all that time the translucent wall lets sunlight warm it. Standing warm water in daylight is an ideal nursery for algae and biofilm, so the very calm that keeps a concrete tank clear works against a plastic one, because plastic passes the light that concrete blocks.
The second factor is the age of the plumbing feeding these tanks. Older masonry sumps let in grit through hairline cracks, and that fine sediment travels up and settles on the plastic floor of the overhead tank. Once a soft layer is down, the algae film has a rough surface to grip, and with staff rarely opening the lid the film thickens quietly. It is why an annual clean matters in Civil Lines even where the piped water itself looks perfectly clear.
No travel charge anywhere in Civil Lines. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our tank is large and only lightly used, does that make cleaning less urgent?” It actually makes it more worthwhile. Water that sits for days in a big translucent Sintex tank warms in the sun and grows algae precisely because it is standing still. A large, slow-turnover tank in Civil Lines often carries more film than a busy one, so an annual clean is well placed even if the water looks clear at the tap.
“The staff handle the property, can they simply be there instead of us?” Yes, that is common in Civil Lines. As long as someone can show our crew the tank and its access, and confirm the supply timing, the household need not be present. We send the before-and-after photos to whoever you nominate so you can see the finished tank even if you were not on site.
“What does a large Sintex overhead tank cost to clean here?” A 1000 to 2000 litre plastic tank falls in the ₹1,299 to ₹1,499 range, a standard 1000L is ₹899, and a smaller tank up to 500 litres is ₹699. Bungalows that keep more than one plastic tank get a bulk per-tank rate, which usually brings the whole-house cost down.
“Will jet-washing damage an older Sintex tank?” No. We set the jet pressure for plastic specifically, so it lifts film and sediment without cutting into the wall, and we use soft pads rather than wire brushes. That matters most on tanks that have been in place many years, where a harsh brush would scratch the plastic and give algae an even easier grip next time.
“How long does the whole clean take on a big bungalow tank?” A single large Sintex overhead tank is usually done within a couple of hours from draining to the final rinse, depending on how much sediment has built up. We work around your supply hours so the tank is not left empty when you need water, and you have it back clean and refilling by the end of the visit.
