Underground Water Tank Cleaning in Whitefield

Why sumps need attention

Many Bangalore properties store BWSSB, borewell or tanker water in an underground sump before it is pumped to the overhead tank. Because sumps are below ground, silt and sediment settle easily, and problems are rarely noticed until water quality at the tap changes.

Cleaning a sump also helps the overhead tank: less sediment is pumped upward each time the motor runs.

How we approach underground tank cleaning

• Understanding the sump size, depth, manhole access and inlet/outlet arrangement.
• Draining water and removing accumulated silt and sludge.
• Cleaning the walls and floor using a method appropriate to the structure.
• Final checks and guidance on refilling and aftercare.

Access and safety

Underground tanks are confined spaces. We assess access before starting and may ask about the manhole size and ventilation when you contact us. Please keep children and pets away from the open sump during the work.

Many customers combine this with overhead tank cleaning. For residential complexes, see apartment water tank cleaning.
