Water Tank Cleaning Service in Dhaka | Overhead Tank & Reservoir

The water your family drinks, cooks and bathes with is only as clean as the tank it is stored in. Over months, sludge, sediment, rust, algae and bacteria settle in the bottom of rooftop tanks and underground reservoirs, quietly contaminating your supply and causing stomach illness, skin problems and bad-tasting water. CleaningBD's water tank cleaning service in Dhaka removes all of it and disinfects the tank to a safe, hygienic standard.

We clean both types of tank — overhead / rooftop tanks and underground reservoirs — whether plastic, concrete or steel. Our trained team arrives with the right equipment and safe disinfectants, and gives you before-and-after photos so you can see exactly what was removed.

Overhead / Rooftop Water Tank Cleaning

Plastic and concrete tanks on the roof collect dust, algae and sediment fast. We drain the tank, remove the settled sludge at the bottom, high-pressure scrub the walls and floor, disinfect with a safe anti-bacterial solution, and leave it ready to refill — the overhead tank that feeds your taps, cleaned properly.

Underground Reservoir Tank Cleaning

Large underground reservoirs build up a thick layer of sludge and sediment at the base that clogs pumps and pipes. We pump out the water and sludge, remove the settled deposits by hand, high-pressure wash and disinfect — ideal for apartment buildings, offices and commercial premises.

How We Work

1

Inspection & Draining

We inspect the tank, then drain the remaining water and the settled sludge at the bottom.

2

Sludge & Sediment Removal

The mud, sand and rust packed at the base are removed by hand — the part ordinary rinsing never touches.

3

High-Pressure Scrubbing

Walls, floor and corners are scrubbed with high-pressure jets to strip off algae, biofilm and stains.

4

Disinfection & Photos

We treat the tank with a safe anti-bacterial disinfectant and hand you before/after photos.

Why Choose CleaningBD

You cannot easily see inside your own water tank, so trust and thoroughness matter more here than almost any other cleaning job. We document the work with before-and-after photos, use safe anti-bacterial disinfectants to WHO-recommended standards, and remove sludge by hand rather than just flushing water through. Our trained team cleans plastic, concrete and steel tanks — overhead and underground alike — usually finishing a domestic tank the same day.
