Professional cleaning and disinfection of underground and overhead water tanks across Karachi since 2007. See your rate online in under a minute, and pay only after you have checked the tank yourself.
In Karachi's demanding water supply environment, a contaminated water tank is not a minor inconvenience — it is a direct threat to the health of everyone who depends on it. Underground and overhead water tanks quietly accumulate sludge, sediment, rust, algae, bacteria, and harmful microorganisms that degrade water quality long before the problem becomes visible.
We provide professional, systematic water tank cleaning services across Karachi, designed to eliminate contamination at the source — not mask it. Our trained team follows the same sequence on every job: drain the tank, remove the sludge, pressure-wash the walls and floor, vacuum out the waste water, disinfect, and rinse. Each stage is explained on our service procedure page.
Founded in 2007, Karachi Tank Cleaning is a water tank cleaning company that now completes four to five home jobs a day across the city, alongside its commercial and industrial work. The company is registered with the Sindh Revenue Board (SRB) and the Federal Board of Revenue (FBR), and holds ISO 45001 certification, the international standard for occupational health and safety. You can check every document yourself on our certificates page.
For disinfection we use chlorine-based disinfectants (calcium hypochlorite or sodium hypochlorite). Chlorination is the disinfection method set out in the WHO technical note on cleaning and disinfecting water storage tanks. After the contact time, the tank is rinsed before it refills. Commercial and industrial clients who require a specific product from their own approved list get the job done with that product. The details are on our cleaning chemicals page.
We serve residential, commercial, industrial, and institutional clients across all areas of Karachi — including houses, apartments, offices, hospitals, schools, restaurants, factories, and construction sites. A standard house tank is cleaned with a pump, a pressure washer, a vacuum and protective gear. Deep underground tanks and factory tanks get extra safety equipment and ventilation, as set out on our safety page.
Water tanks that aren't cleaned regularly can harbor bacteria such as E. coli and Legionella. Sediment buildup lowers water quality and can clog pipes, taps and filters. We recommend professional cleaning every 6 months, and sooner if the water changes colour or starts to smell.
The two tanks in a Karachi house fill in different ways, so they collect different things.
Line water and tanker water arrive here first, so this is where sand and silt settle. Over the months that layer turns into sludge on the floor. A cracked wall or a loose cover can also let in seepage from the ground around the tank.
Water is pumped up from the underground tank, so less silt reaches the roof. Fine particles still settle, and a slippery film builds up on the walls. A cover that does not close properly lets in dust, leaves, birds and lizards.
These tanks sit in direct sunlight. When light gets inside, through a missing lid or thin walls, algae grows and the water turns green. Their smooth walls are quicker to wash, but they need disinfecting just the same.
From residential homes to large industrial facilities, the work is matched to the property and the type of tank.
Professional cleaning for RCC/cement underground and overhead water tanks, and for plastic and fiber overhead tanks, in residential homes of every size. House rates are fixed by plot size or tank capacity, so you can see your price in the calculator above before you book.
Water tank cleaning for shared overhead and underground tanks in apartment buildings, and for individual tanks in portions and flats. Access and tank sizes differ from building to building, so we visit for a free survey first and quote after seeing the tank.
Offices, shopping centers, hotels, restaurants, schools and hospitals. After the job you receive a tax invoice and a cleaning certificate that you can show to an auditor or the health department. See the businesses we have worked for.
Factories, warehouses and plants with large storage tanks. These jobs are planned after a site survey and carried out with extra safety equipment for deep and confined tanks. If your company requires a disinfectant from its own approved list, we work with it.
We answer calls 24 hours a day for urgent tank cleaning. If something has contaminated your tank, such as sewage mixing with line water or a dead bird or lizard, call us and we will send a team the same day wherever possible.

After the job. Before the team packs up, we ask you to look inside the tank yourself. If something is not right, it is redone on the spot. You pay once you are satisfied.
A cleaned tank stays only as clean as the water that goes into it. In Karachi, line water after a supply gap, tanker water and boring water can all bring fresh silt and colour into a tank within days. That comes from the incoming water, not from the cleaning. If the problem is with our work, we come back and re-service it. The terms are on our service guarantee page.
Yes. We are open 24 hours and keep same-day slots for urgent jobs. Call 0313-2796778.
