Sediment removal, scrubbing and chlorination for overhead tanks and sumps. Essential for safe drinking water.
Most households clean their home regularly — but forget the water tank. Over time, sediment, algae, rust particles, dead insects and bacterial biofilm accumulate at the bottom and along the walls of overhead tanks and underground sumps. This contaminated water then flows to your taps, your cooking pots and your drinking glasses.
Regular water tank cleaning is not just about hygiene — it's a public health requirement. Clean Warks provides professional tank cleaning with complete sediment removal, high-pressure wall scrubbing and chlorine disinfection, bringing your water storage back to safe standards.
In Bangalore, most apartment complexes and independent houses rely on underground sumps rather than overhead tanks alone. These sumps collect water from borewells and municipal supply before pumping it to overhead tanks — making sump hygiene critical for your entire building's water quality.
Clean Warks provides professional sump cleaning across Bangalore, including complete water extraction, high-pressure wall scrubbing, sludge removal and food-grade chlorination. Whether your sump is 1,000 litres or 50,000 litres, our team arrives with the right equipment. We serve individual apartments, gated communities, apartment associations and commercial buildings.
Water is pumped out and all accumulated sediment, sludge and debris at the tank floor is removed using suction equipment and manual tools.
Interior walls, floor and lid of the tank scrubbed with high-pressure equipment to remove biofilm, algae growth and hardened mineral deposits.
After scrubbing, the tank is disinfected with food-grade chlorine solution that kills bacteria, viruses and pathogens — then flushed and refilled safely.
We clean both underground sumps and rooftop overhead tanks — any size, any material including PVC, concrete, HDPE and ferro-cement.
On completion, we provide a service report with details of the cleaning carried out. Optional water quality testing available on request.
The WHO recommends cleaning water storage tanks every 3–6 months. We offer quarterly maintenance plans at discounted rates for homes and apartments.
For a family home, cleaning your overhead tank every 3–6 months is recommended. Underground sumps may need more frequent attention depending on water source quality. During monsoon season, when water quality can be unpredictable, a post-monsoon tank clean is strongly advised.

Sediment, algae and bacteria accumulate inside tanks over time, contaminating your water supply. Regular cleaning prevents waterborne diseases and extends tank life.
Every 6 months for overhead tanks and sumps is recommended by health authorities. Tanks with high sediment levels may need quarterly cleaning.
Draining the tank, scrubbing all interior walls and base, removing sediment and slime, disinfecting with food-grade chlorine solution, rinsing and refilling.
1–2 hours for a standard 500–1000 litre overhead tank. Larger underground sumps may take 3–4 hours.
Yes — we use food-grade disinfectants. Water is safe to use after the tank fills and a brief settling period (30–60 minutes). We advise running taps for a minute before use.

A sump is an underground water storage tank that collects borewell or municipal water before it's pumped to your overhead tank. In Bangalore's hard water conditions, sumps accumulate sediment, algae and bacteria faster than overhead tanks. Regular sump cleaning ensures your entire water supply — cooking, drinking, bathing — comes from a hygienic source.
Every 3–6 months is recommended for residential sumps. Apartment complex sumps serving multiple households may need cleaning every 2–3 months depending on water quality and usage. We offer quarterly maintenance plans for housing societies at group rates.
Yes — we clean both underground sumps and rooftop overhead tanks across Bangalore and Kerala. The process includes draining, scrubbing, sediment removal and chlorine disinfection for both types.
