How Often Should You Clean Your Water Tank?

Hari Nagar Ashram — a compact colony of narrow lanes and three- and four-storey walk-ups tucked behind Ashram Chowk, where weak tail-end DJB pressure keeps every roof stacked with borewell-fed tanks. We descale and disinfect them, from ₹699.
Hari Nagar Ashram sits at the tail end of its DJB line, and the pressure shows it — ground floors get a trickle, upper floors get almost nothing. So nearly every building runs a borewell backup, and roofs carry either one plastic tank per floor or a single larger shared unit. Borewell water in this Yamuna-side pocket is hard, and it lays down white scale on tank walls and float valves far faster than the DJB-only colonies a kilometre west.
The lanes themselves shape the job: most are too narrow for anything larger than a two-wheeler, staircases turn tight, and parapet walls are low. Tanks here also cycle empty-to-full more often than usual because families alternate between the weak DJB feed and borewell top-ups, and that constant refill churn layers sediment at the base in stripes. Owners who open a five-year-old tank here are usually shocked at what a season of borewell water leaves behind.
For a standard 1000-litre overhead tank, the whole job takes about 90 minutes from doorbell to pack-up. Underground sumps take longer — usually 2 to 2.5 hours depending on sludge. You don’t need to provide anything: we bring our own water for the rinse, vacuums, jet pumps, food-grade disinfectant and gloves, and send before/after photos on WhatsApp.
A typical building here has three or four floors, each family with its own 500L tank on the shared roof, plus sometimes a common tank for the ground floor. Cleaning one tank while its neighbours stay dirty is a half-measure — splash-over and shared inlet lines undo it — so we quote the whole roof in one visit: ₹699 per tank up to 500L, done back-to-back so the building loses water for a morning, not a day. Each family gets its own before-and-after photos.
Because DJB pressure dies before it reaches these lanes, borewells do most of the filling, and hard groundwater means scale — a chalky crust on walls, around outlets and inside float valves that shrinks tank capacity and jams fittings. Our clean includes mechanical descaling with high-pressure jets and scrub pads, not just a rinse, followed by food-grade disinfection. On borewell-heavy roofs like these we recommend a clean every six months rather than the annual cycle piped colonies get away with.
“Our building in Hari Nagar Ashram runs mostly on borewell — how often should tanks be cleaned?” Every six months. Hard borewell water scales tanks two to three times faster than DJB supply, and by month eight the crust starts flaking into the outlet. We can put your building on a fixed six-monthly reminder so nobody has to track it.
“Can your team get equipment into our lane? Cars can’t enter.” Yes — that’s normal here. We park on the Ring Road edge or near Ashram Chowk and hand-carry the pump, jet unit and hoses in. Nothing we use needs vehicle access to the building itself.
“There are four separate tanks on our roof, one per floor. What does that cost?” ₹699 per tank up to 500L (₹899 for 501–1,000L), cleaned back-to-back in one visit of around three to four hours. Booking the whole roof together is cheaper and cleaner than four separate visits, and each family receives its own photo proof.
