Professional Water Tank Cleaning Services in Delhi NCR

Water tank cleaning for homes, societies and businesses across Delhi NCR

CHKACHK cleans the water tanks that most households in Delhi NCR depend on — the plastic tank on the roof, the concrete sump under the driveway, and the large storage tanks that serve apartment blocks, offices and shops. We work from our office at CB-156, Naraina Village, New Delhi, and serve Delhi, Noida, Greater Noida, Gurgaon, Ghaziabad and Faridabad.

Water reaches most homes here after a long journey: from the municipal line or a borewell, sometimes via a tanker, into a sump, then up to a rooftop tank. Each stop leaves something behind. Fine silt settles on the floor, a slimy biofilm forms on the walls, and if any light gets in, algae follows. None of this is visible from the tap until the water starts to smell, look cloudy or leave residue in your buckets and filters. A proper cleaning removes that build-up at the source instead of leaving your RO, geyser and pipes to deal with it.

What a CHKACHK tank cleaning includes

Every booking — whether a 500-litre rooftop tank or a 30,000-litre underground reservoir — follows the same five-step method. Nothing is skipped on smaller tanks.

The difference between a proper clean and a quick rinse is mostly in step two. Scrubbing a tank that still has sludge on the floor simply stirs the dirt into suspension, and it settles back as soon as you refill. Our team lifts the sludge out with a vacuum machine first, then scrubs and pressure-washes the clean surfaces, and only then disinfects. Most standard household tanks in the 500–2,000 litre range are finished in about 45 to 60 minutes; underground tanks and multi-tank bookings take longer.

Transparent prices — per tank, by capacity

Prices depend on two things only: whether the tank is overhead or underground, and its maximum capacity. You can see every price before you book. A 1,000-litre overhead tank costs ₹599, and a typical 1,501–3,000 litre underground sump costs ₹1,099.

Clean more tanks in one visit, pay less per tank

Most homes have at least two tanks — one on the roof and one underground — and many buildings have several. When you book more than one tank in the same visit, a quantity discount is applied automatically to the cleaning subtotal. Overhead and underground tanks of any size count together.

A transportation charge may apply, once per booking, not per tank, based on the road distance from our Naraina office to your PIN code. It is free within 10 km and never more than ₹100. If we haven't verified the distance to your PIN code yet, our team confirms it before you pay — we never guess. Full details are on our water tank cleaning price list.

Why customers in Delhi NCR choose CHKACHK

• You see the price first. Every capacity band has a fixed published price, and the multi-tank discount and transport charge are calculated in front of you before you book.
• Sludge is removed, not just stirred. Vacuum de-sludging comes before scrubbing, so the dirt actually leaves the tank.
• Photo proof. You receive before-and-after photos on WhatsApp, which is especially useful when the tank is on a roof you don't climb or the sump is under a slab.
• One team for every tank type. Plastic rooftop tanks, concrete sumps, loft tanks and large society reservoirs are all handled by the same trained crew.
• Pay the way you prefer. Pay after the job is done, or pay online when you book.
• A rating you can check yourself. CHKACHK holds a 4.8-star rating from 1,854 reviews on its Google Business Profile — read them directly on Google rather than relying on a selection here.

How booking works

1. Add your tanks. Choose overhead or underground and the capacity of each tank. Add as many as you need; the discount updates as you go.
2. Check your PIN code. We show the transport charge for verified PIN codes, or confirm it with you if your PIN hasn't been verified yet.
3. Pick a date and time slot. Tell us about access — a locked terrace, a sump under a parked car, or a society gate pass.
4. Pay online or after the service. You receive a booking ID straight away and a confirmation from our team.

How often should a water tank be cleaned?

For most homes in Delhi NCR, cleaning a tank about every six months is a sensible routine. Clean more often if your tank is translucent or in direct sun, if you rely on tanker or borewell water, if the lid doesn't seal properly, or if anyone at home has a weak immune system. Clean immediately after the monsoon if rainwater or dust may have entered, and any time the water smells, tastes odd or looks cloudy. Our guide on how often you should clean your water tank explains the signs in more detail.

Tip: If you're booking for a building, clean the underground sump and the overhead tanks on the same day. Cleaning only the rooftop tank means it refills from a dirty sump.
