Water Tank cleaning & Pipeline Disinfection
Water Tank Cleaning
Domestic, Commercial and Industrial water systems are fed from dedicated water storage tanks that in turn are fed from local water supply systems. Contaminated or dirty water is potentially a very severe health hazard, badly maintained water storage tanks are a major contributory factor. All water tanks and the associated pipelines must be regularly inspected, maintained, cleaned and disinfected in line with local and International standards.
Inspecting and Cleaning a (Hot and Cold) Water System
a) Water systems (hot & cold water) must be flushed at least every six months with water of not less than 70 °C for 5 minutes (or an equivalent temperature/time combination) or treated with chlorine to provide minimum free chlorine residual of 1-2 mg/l at all outlets.
b) Reduce dead legs (stagnant lines and stubs) in the system,
c) Clean and inspect hot water tanks regularly – annually as a minimum,
d) Continually run hot water circulation pumps – avoid recycling to mixing valves only,
e) Store hot water at a minimum temperature of 60 °C (140 °F) and deliver to the taps at a minimum temperature of 50 °C (122 °F),
f) Store and distribute the cold domestic water below 20 °C (68 °F) – if not possible , then consider monitoring of Legionella and using a disinfection system if Legionella is not under control,
g) Flush the entire water system on a regular basis (at least quarterly),
h) Consider routine treatments – including the use of approved biocides.
