How Long Does Tank Cleaning Take?

Many of the rooftop tanks in Rajgarh Colony are nineties-era Sintex, aged well past their comfortable life, their inner walls roughened until they hold sediment stubbornly. On regular East Delhi DJB the water is only moderately hard, yet these tired tanks still trap a layer that clouds the supply. Cleaning one starts from ₹699.
The tank stock here is the story: decades-old Sintex, its plastic gone rough and porous inside so sediment clings where it would once have rinsed clean. This is an established colony near the Krishna Nagar border, mostly older 3 and 4 storey buildings on ordinary DJB, with a small tank per floor. Long-term residents run these tanks quietly and tend to clean only when the water visibly turns. By then the roughened walls are holding a firm layer of sediment and the base has silted. The moderate supply keeps things slow, but slow is not the same as clean. We take the tank back with a full drain, a careful hand scrub, a vacuum of the base, and an anti-bacterial disinfectant wash.
This page is about the rooftop and overhead tanks on your terrace, the ageing Sintex tanks that most buildings here still run. For the complete service across sumps and underground tanks, see water tank cleaning in Rajgarh Colony. We bring our own ladder, pump and vacuum and work independently once we have roof access. A single tank is usually done within the hour, and more than one tank in a building earns a bulk discount. Before-and-after photos come with every job.
The pattern here is set by the residents. Long-term owners run a tank per floor and, with no rush and no landlord to answer to, they clean only when the water finally looks wrong. That leaves long gaps in which sediment settles undisturbed on the base. In an old tank that gap does real damage, because the layer sets firm before anyone acts.
The condition of the plastic makes those gaps costlier. Nineties Sintex that has weathered decades of sun and refills goes rough and slightly porous inside, and a rough wall holds sediment and scale that a newer tank would let go. So even on moderate DJB water these tanks accumulate a stubborn layer. A clean every four to six months keeps ahead of it and keeps old tanks serviceable for years more.
No travel charge anywhere in Rajgarh Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

“How often should these older tanks be cleaned?” On moderate DJB water, every four to six months is a sensible interval for the ageing tanks here. Because the walls are rough and hold sediment, do not stretch it much beyond that. We can remind you when the next one is due.
“The tank has not been cleaned in years, what will come out?” On a first deep clean of an old tank, expect a firm layer of settled sediment and scale off the base and walls. It can take a little longer than a routine visit, but the tank comes back clear and usable. You will see it all in the before-and-after photos.
“Will scrubbing harm my old Sintex tank?” No, we hand scrub with the right tools and take care with older plastic. We lift the sediment and scale without cutting into a sound tank, and if we spot a crack or weak spot we will point it out. Cleaning extends the life of a tired tank rather than shortening it.
“What will it cost for the tanks in my building?” A single tank starts from ₹699 and rises with size, up to ₹1,299 to ₹1,499 for a 1500 to 2000 litre tank. When we clean more than one tank in the same visit we apply a bulk discount. Tell us the sizes and count for a full quote.
“How do I book, and can you reach the inner lanes?” Call or WhatsApp your location near the Krishna Nagar border and how many tanks you have, and we will confirm a time. We work these lanes regularly and reach the roofs on foot with our own ladder. You pay once the job is done.
