The control of water hygiene and water quality is a requirement for building owners and managers. Compliance with the regulations and maintaining the quality of water storage and distribution inline with the HSG274 Guidance is essential in reducing the risk of legionella proliferation in the systems.
The correct storage of cold water is an integral component of an effective water hygiene regime. Tank refurbishment is often an effective way to immediately improve water quality. Replacement / Refurbishment of water tanks can be required due to a poor condition of the existing tank or because it is over-sized.
An existing tank should only hold a maximum 24 hours water supply. Your L8 Risk Assessment will identify if either of these apply to your premises.
