We cover all of Greater Manchester from our Leeds base, including Bolton, Stockport, Salford, Trafford, Wigan and Bury. If a cold water tank there is dirty, oversized or has not been looked at for a long time, a clean and disinfection puts it right and gives you the paperwork to prove it.
Water Hygiene Services is an independent Legionella control company based in Leeds. We clean and disinfect cold water tanks for estates managers, facilities managers and building and property managers across Greater Manchester. For the city centre, see our Manchester pages.

What is a cold water tank clean and disinfection?
A tank clean removes sediment, scale, rust, sludge and biofilm from the inside of a cold water storage tank. The tank is then disinfected using an approved method and contact time, so bacteria levels fall and the stored water is safe to use. We work to HSG274, supporting ACoP L8.
Cleaning and disinfection are linked but not the same. Cleaning removes physical contamination, and disinfection treats the tank and the system afterwards. In most cases both are needed, because disinfecting a dirty tank does not last. For the full detail, see our Tank Cleaning and Disinfection page.
- Visible dirt, sediment or sludge in the tank
- Rust staining
- Damaged lids or missing insect screens
- Stale or discoloured water
- Poor microbiological results
- A tank that has been unused, repaired or altered

Questions we are asked in Greater Manchester
We have tanks at several sites across Greater Manchester. Can the cleans be grouped?
Yes. We group the cleans by area so each trip covers as many sites as possible.
How often should a tank be cleaned?
There is no single frequency for every tank. HSG274 expects tanks to be inspected regularly, and cleaned and disinfected where inspection shows it is needed.
