Hard Water Tank Cleaning in Delhi

Did you know a Rana Pratap Bagh home usually stores its water twice, in the sump and again in a Sintex tank, so both foul in the dark? KaamGenie cleans the plastic tank gently and hygienically. From ₹699.
Here is a fact many Rana Pratap Bagh residents overlook: the water reaches the tap only after sitting in two places. This settled residential colony near Kamla Nagar and Shakti Nagar, made up of older independent houses and newer builder floors on DJB piped supply, draws water into an underground sump and then pumps it up to an overhead tank, and on many buildings that overhead tank is a Sintex or plastic one. Water that settles twice drops sediment in both vessels between the municipal fills. In the plastic overhead tank a second thing happens: light passes through the translucent wall and warms the water, so an algae film grows on top of the settled silt. The ageing plumbing on many of these decades-old plots adds rust to the mix. Because both the tank and the sump stay closed for years, sludge builds quietly in each until a proper clean removes it.
Our plastic-safe clean handles the overhead Sintex tank the gentle way: we check the tank and lid, drain it, scoop the slimy and rusty sediment off the bottom, wet-vacuum the residue, jet-wash at a plastic-safe pressure, scrub the algae with soft pads, then an anti-bacterial disinfectant wash and photos before and after. Since the sump is half the story here, our full water tank cleaning in Rana Pratap Bagh covers the underground sump too. This page focuses on the Sintex and plastic overhead tanks.
The double-storage setup is the root of it. Water settles once in the underground sump and again in the overhead tank, and each time it drops fine silt and, on older plots, rust from the ageing pipes. So sediment collects in two places, not one, and because both stay sealed and out of sight for years, nobody clears it until it has thickened into a real sludge layer at the bottom of each vessel.
The overhead tank then adds the algae problem the sump does not have. A translucent Sintex wall lets rooftop sunlight into the water and warms it, growing a green film on top of the settled silt, where a dark underground sump stays cool and lightless. That is why the plastic overhead tank often looks worse than the sump feeding it, and why cleaning both, the sump for its sludge and the Sintex tank for sludge plus film, gives you clean water end to end.
No travel charge anywhere in Rana Pratap Bagh. The final price is confirmed on the call before we come — it depends only on tank size and access.

“If both our sump and Sintex tank store the water, should we clean both?” Ideally yes, because sediment settles in each and the water passes through both before it reaches your tap. This page’s service covers the plastic overhead tank, and we can do the underground sump in the same visit, so your whole line from sump to Sintex tank is clear rather than just the top half.
“Which one usually looks dirtier, the sump or the plastic tank?” Often the plastic overhead tank, because sunlight through its wall grows an algae film the dark sump never gets. The sump collects silt and sludge but stays cool and lightless, so it fouls more slowly. Both hold sediment, but the Sintex tank tends to carry the green film on top of it.
“Our plot is old with ageing pipes, does that add to the problem?” It does. Old plumbing sheds rust and grit into both the sump and the overhead tank, adding to the settled silt and giving the algae a rough surface to grip inside the plastic tank. Clearing the tank removes that build-up; cleaning both the sump and the tank keeps the whole stored supply clean.
“What does it cost to clean the overhead Sintex tank?” A standard 1000L Sintex is ₹899 and a 500 litre one is ₹699, with a 1000 to 2000 litre tank at ₹1,299 to ₹1,499. If you have the sump done alongside, or the building keeps more than one plastic tank, a bulk rate brings the combined cost down.
“How long since a clean is too long for a sump-and-tank setup?” Many Rana Pratap Bagh homes go years without opening either, and that is when the sludge gets thick. Doing both once a year keeps sediment from building in the sump and film from settling in the Sintex tank, so the water never reaches the point of tasting or smelling of what has collected.
