Underground Water Tank Cleaning Tips

We all know how important water tank cleaning in Karachi is for people living in the city of Karachi. Proper cleaning ensures that the tank does not become clogged or damaged and that it continues to perform its functions efficiently. The frequency of cleaning depends on how much debris accumulates within the tank. For example, if you live in an area where there are few trees or bushes, then you may only need to clean your water tank once every two months or even once every year. However, if you live in an area with lots of dust, many trees and bushes then you may need to clean it more regularly – perhaps every second month.

Below are some of the very important tips and considerations you should keep in mind when it comes to water tank cleaning:

Remove the Stagnant Water

Stagnant water can be dangerous and should be removed immediately. Stagnant water contains algae and other microorganisms that can release toxins into your drinking water. You should not drink from a stagnant tank if you have an open wound, or if you have consumed alcohol within the previous 24 hours. If you suspect your drinking water has been contaminated by any of these substances, seek medical attention immediately.

Disinfection and Chlorination

Disinfection and chlorination is a process of killing bacteria that may have entered the water tanks. It is an important step because it prevents contamination of the water by bacteria. You can disinfect your domestic water tank by adding chlorine tablets or powder in the tank. Alternatively, boil the water for at least two minutes or add one tablespoon per gallon of household bleach (5% sodium hypochlorite). Allow 30 minutes contact time before discarding it in an outdoor area away from children and pets so that they don’t drink it accidentally (and die). This method does not work well for cloudy or colored liquids but does work well for clear liquids like rainwater, river/lake/ocean water, etc.

Disinfection of the inner surfaces of the tank is also essential. Use a disinfectant that is suitable for the material of your tank. For example, if you have a plastic or fibreglass tank, it must be cleaned with hot water and detergent. If your water tank is made of cement or brick, then use an acid-based bleach solution.

Clean the Pipe Lines and Outlet Taps

Make sure you clean the pipe lines and outlet taps before washing out your water tank. You can use a pipe cleaner or a hose. If you choose to use a hose, make sure that it is well-rinsed before using it again. If you have any removable sprayers on your taps, remove them from the tap and wash them in hot soapy water; this will help prevent any build-up in future. Then rinse all parts thoroughly under running water to remove any soap residue. If possible, use a brush to clean around the outlet taps and make sure there are no blockages or deposits where they join with other components such as pipes leading into drainpipes or dishwashers etc.

Scrub the Interior Walls Thoroughly

Use a brush to scrub the inside of the tank. This can be a large wire brush for a large tank or smaller brushes for smaller ones. The aim is to scrub away as much built up dirt from around and in between fittings, such as taps and valves. While scrubbing, use a suitable detergent or disinfectant that is recommended for use on domestic water tanks. Clean all surfaces with soft cotton cloths dipped in water then wrung out thoroughly before wiping each surface with them gently but firmly while being careful not to scratch any part of them too hard either!

System Recommissioning

The system recommissioning process involves draining all the tanks and removing any debris left behind by insects and rodents as well as checking for leaks etc. This is an important step before the water tank cleaning is considered as completed.


It’s important that you clean your domestic water tanks regularly, at least twice a year, preferably in springtime when temperatures are cooler than they might otherwise be during summer months that follow directly afterwards. If you don’t, then the bacteria and mould will grow in there and cause serious health problems for you and your family. We recommend that you hire a professional janitorial services company to do this for you, especially if your water tank is in an awkward place or too dirty to clean. If your water tank is not too deep and too dirty, then you can DIY without any problems.
