10000 Litre Underground Water Tank Cleaning

Which tanks this package covers

This package covers underground tanks with a maximum capacity from 5,001 to 10,000 litres:

• Reservoirs for multi-floor apartment buildings and small societies.
• Storage tanks for schools, coaching centres, offices and hospitals.
• Large house sumps built to store water for days during supply shortages.
• Individual chambers of a larger divided reservoir (each chamber priced separately).

For a 10,000-litre overhead tank, choose the 6,000–10,000 litre overhead package.

Why tanks of this size are built — and why they get dirty

Many Delhi NCR buildings store several days' worth of water because supply is intermittent or unreliable. A 10,000-litre reservoir lets a building ride out a missed supply day or wait for a tanker. The trade-off is that water sits longer, residual chlorine fades, and sediment from every delivery settles. Tanks that receive tanker water in particular can accumulate a heavy sludge layer.

How we approach a large sump

• Ventilation and safety first. Large sumps are confined spaces with limited air exchange. The tank is ventilated before entry and a team member stays at the opening throughout.
• Draining with high-capacity pumps, so the tank is empty before cleaning starts.
• Vacuum de-sludging across the whole floor area, paying attention to corners and the area below the inlet where sediment piles up.
• Scrubbing and pressure-washing walls and the underside of the slab, then disinfection and rinse.

Expect the job to take longer than a household tank; our team will estimate when confirming the slot.

What's included

• Draining the remaining water with a motor
• Vacuum removal of settled sludge
• Scrubbing and pressure-washing of walls, floor, corners and lid
• Anti-bacterial disinfection and rinse
• Before-and-after photos on WhatsApp

Price and discounts

This package costs ₹2,599 per tank. Add more tanks of any size or type to the same booking and the cleaning subtotal is discounted automatically:

A transportation charge may apply, once per booking by PIN code — free within 10 km of our Naraina office and never more than ₹100.

Plan the building's supply

Before the slot, fill overhead tanks fully so the building has stored water while the reservoir is being cleaned. Then clean the overhead tanks after the reservoir — the second, third and further tanks increase your discount. For schools, offices and societies, see commercial water tank cleaning for scheduling options.

10000 litre water tank cleaning price, explained

₹2,599 covers one underground tank of 5,001–10,000 litres — common for buildings with several families, guest houses and small offices. Because the tank is large, our team works inside it with lighting and ventilation, and removes sludge by vacuum before scrubbing.
