It provides guidance on cleaning, flushing and disinfecting water supply systems to control microbiological growth and remove debris.
Who is this standard for?
- Public health professionals
- Regulators
- Water treatment companies
- Building services engineers
- Plumbing and pipeline contractors
- Owners of public buildings
Why should you use this standard?
Flushing and disinfection were previously included in BS 8558:2011, but the relevant section has now been extracted, expanded and published separately as PD 855468, which includes guidance on how to:
- Deploy the right tools and personnel
- Use appropriate disinfectants and processes
- Respond if a microbiological problem is identified
- Keep records of cleaning
The document applies to systems for supply, storage and distribution of water for domestic purposes within buildings and their curtilages. It includes water used to make food, but excludes closed systems and other industrial processes.
Whether you are preparing new systems, or maintaining or altering existing systems, PD 855468 will help you achieve high water quality and minimize the risks of corrosion and damage.
