What is PD 855468- Guide on flushing and disinfection of services supplying water about?
PD 855468 has been developed to build on the guidance previously given in BS 8558 on the flushing and disinfection of services supplying water for domestic use within buildings and their curtilages. PD 855468 provides guidance on cleaning, flushing and disinfecting water supply systems to control microbiological growth and remove debris.
PD 855468 provides guidance on cleaning, flushing and disinfection of services supplying water for domestic purposes within buildings and their curtilages, including those for the production of foods.
The main objective of the best industry guidance and recommendations provided by PD 855468, is to ensure supply of water is safe to consume while also minimizing the risk of corrosion and damage.
The guidance applies to:
- Initial commissioning of new or extended systems
- Maintenance of existing systems
- Alteration of existing systems
- Water quality management prior to occupation or as a result of low/no occupancy or usage
- (remedial) response to microbiological problems is identified.
Note 1: The techniques set out in this standard are also applicable to the management of premises and systems where water is provided from a private supply.
Note 2: PD 855468 excludes closed systems and other industrial processes.
