Water Tank Cleaning

 

Overtime cold water storage tanks, often found in lofts, basements and airing cupboards become dirty with debris, sediment, scale, sludge, biofilm, fouling, wall mould, stagnation, rust, corrosion, foreign bodies and even plant growth. Should contaminants enter our water tanks or build up over time, they provide a breading ground for bacteria such as legionella and E.coli.

An annual inspection of cold water storage tanks will determine if cleaning and/or disinfection is required, as stated in the ACoP L8 (HSG 274 Part 2).

Why do I need to clean my water tank?

 

To maintain good quality water it is important that tanks are inspected regularly and cleaned when required to prevent bacterial proliferation. Protecting the water system’s users from potentially fatal diseases such as legionnaires disease is vital. Particularly when the users are vulnerable people such as: children, the elderly, people with pre-existing illnesses, smokers, etc. 

What else must I do with my cold water tank?

 

Not only is it important to check cold water storage tanks for their internal conditions for water tank cleaning but they must meet design regulations which help prevent bacterial growth inside the tanks. A poorly designed tank, clean or not clean may provide the right conditions for bacteria growth. For example, if your tank does not have a closely fitted lid, insects and bacteria may enter your tank. This is why tank design is just as important as a clean tank.

In summary, you must clean your tank where required, ensure it meets design regulations, and monitor your tank six monthly for its condition, design and temperature. Bacteria sampling is recommended on a six monthly basis to interpret the tank’s water quality. Legionella bacteria can double every 15 minutes.

About the tank clean and how long will it take?

 

uRisk’s water tank cleaning and disinfection services are carried out by our fully trained engineers, provided with RAMS, method statements and procedures to ensure the work complies with the ACoP L8 (HSG 274) and COSHH regulations. Disinfection works are carried out with the use of chlorine with all RAMS designed to ensure the safety of the water system’s users is paramount.

On average it can take our experience engineers between 3-5 hours to clean your water tanks. However, the time taken to clean the tank often depends on: how dirty the tank is, how accessible the tank is, and the size of the incoming and outgoing pipework from the tanks to list a few factors.
