If a cold water tank in Oldham 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 35 miles from Oldham. We clean and disinfect cold water tanks for estates managers, facilities managers and building and property managers in Oldham.
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

Tank cleaning in Oldham
United Utilities supplies the area. Mill conversions and older buildings often have tanks sized for a past use, holding more water than the building now needs.
We clean tanks in:
- Former mills converted into flats, offices, business units and studios
- Business units and light industrial sites on older estates
- Social housing and sheltered housing with communal hot water systems
- Schools, colleges and community buildings
- Care homes and residential homes
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.
Questions we are asked in Oldham
Our tank was sized for an earlier use of the building. Can it be reduced?
Often, yes. We can advise on reducing storage, and the clean is a good time to look at it.
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.
