If a cold water tank in Huddersfield and Kirklees 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.

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.
