We cover Nottingham and the East Midlands. We are Leeds-based, about 75 miles away, and we plan each visit in advance and group sites together. 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, about 75 miles from Nottingham. We clean and disinfect cold water tanks for estates managers, facilities managers and building and property managers in Nottingham and the East Midlands.

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
- A risk assessment that recommends cleaning
Tank cleaning in Nottingham
Severn Trent supplies the area. Tanks that are bigger than the building needs hold water that turns over slowly, and tanks that nobody has opened for years collect debris.
We clean tanks in:
- Hospitals, clinics and care homes
- University and college buildings
- City centre offices and hotels
- Schools, academies and trusts
- Industrial units and distribution sites
How a tank clean is carried out
- We plan the work with you so the tank can be isolated and drained safely.
- The tank is drained and cleaned inside, removing sediment, scale, rust, sludge and biofilm.
- We check the condition of the lid, screens and fittings, and note any defects.
- The tank and system are disinfected using an approved agent and contact time.
- The system is flushed and returned to service.
- You receive a job sheet and certificate, and notes on any defects found.
