Professional underground sump cleaning for Bangalore apartments and houses. Complete drain, high-pressure scrub and food-grade chlorine disinfection. Serving all Bangalore areas.
An underground sump is a large buried water storage tank found in most Bangalore apartments, independent houses and gated communities. It collects water from borewells and municipal supply lines before a pump pushes it up to overhead tanks and into your home. Every litre of water you drink, cook with or bathe in passes through the sump first.
Over time — typically within 3–6 months — sumps accumulate sediment, sludge, algae, insect debris and bacterial biofilm on their floors and walls. This contaminated water then circulates through your entire building's plumbing system. Unlike overhead tanks that are cleaned more commonly, underground sumps are often forgotten — until residents notice discoloured water, unusual taste, or persistent stomach problems.
Clean Warks provides professional sump cleaning across Bangalore: complete water extraction, high-pressure wall and floor scrubbing, sludge removal and food-grade chlorine disinfection — leaving your sump genuinely clean and your water safe.
Full drainage of the sump using submersible pumps. We remove all standing water before cleaning begins, ensuring no dilution of cleaning agents.
Pressure jet cleaning of all internal surfaces — walls, floor, corners, and inlet/outlet pipes. Removes biofilm, algae, mineral deposits and hardened sediment.
Manual and mechanical removal of all accumulated sludge from the sump floor. This sludge is the primary breeding ground for bacteria and must be physically removed, not just flushed.
Anti-algal treatment applied to sump walls after scrubbing — especially important for sumps receiving borewell water, which promotes algae growth faster than municipal supply.
Final disinfection with food-grade sodium hypochlorite solution — the same standard used for municipal water treatment. Safe for drinking water once fully mixed after refilling.
We inspect sump lid seals and inlet pipe covers for cracks, gaps or damage that allow insects, leaves and surface contaminants to enter. We advise on any repairs needed.
After cleaning, we provide a brief report on sump condition, any findings (cracks, seepage, inadequate sealing) and recommended cleaning frequency for your specific setup.
Bangalore's water situation makes sump hygiene more critical than in most Indian cities:
Bangalore's borewell water is among the hardest in India. Calcium and magnesium deposits form thick scale on sump walls, creating rough surfaces where bacteria colonise more easily.
Many Bangalore apartments rely primarily on borewell water. Borewell water carries significantly higher silt and bacterial loads than treated municipal supply, leading to faster sump contamination.
Bangalore's warm, humid climate accelerates algae and bacterial growth in sumps year-round — unlike cooler cities where biological growth slows in winter.
High-rise apartments generate large daily water demand through multiple sumps. High cycle rates mean faster sediment accumulation and more frequent bacterial recolonisation.
Housing societies and apartment associations across Bangalore trust Clean Warks for their annual or semi-annual sump maintenance. We handle sumps of all capacities — from 5,000 litres to 5,00,000 litres and above. Group booking rates are available for societies that need multiple sumps cleaned in one visit.
We understand the operational constraints of apartment maintenance — we coordinate with your facilities team to minimise water supply disruption and can schedule early-morning or weekend slots.

A sump is an underground water storage tank used in most Bangalore apartments and houses. It collects borewell or municipal water before pumping it to overhead tanks. All home water — drinking, cooking, bathing — passes through the sump first, making its cleanliness critical for your entire household's health.
Every 3–6 months for most residential sumps. Buildings fed by borewell water or with high usage may need cleaning every 2–3 months. Post-monsoon cleaning (October–November) is strongly recommended as monsoon runoff can introduce contaminants.
2–3 hours for a standard 10,000–20,000 litre residential sump. Larger apartment society sumps of 50,000 litres or more typically take 4–6 hours. We'll give you a time estimate when you WhatsApp us.
