CP282  Managing disinfection within a water safety plan framework Water Treatment
The EC and regulatory authorities promoted the WHO concept of Drinking Water Safety Plans (DWSPs) within the international water supply community. In England and Wales, the DWI Information Letter 6/2004 strongly encouraged utilities to develop this approach, particularly in relation to microbiological quality of drinking water. Key features of the approach were:

  • Risk assessment to ensure that appropriate equipment and procedures are in place to protect drinking water quality
  • Documentation to support good operational practices and to demonstrate that these practices are effective.

These features needed to apply from source to tap, to include catchment management, source protection, treatment, distribution and customers' premises.

Disinfection is the main microbiological barrier required by DWI for all waters, but there is little comprehensive guidance available for establishing and maintaining good disinfection practice under UK conditions. The proposed work developed such guidance for the purposes of risk assessment and mitigation, as well as providing recommendations for data management and handling, to demonstrate the operational security of specific supply systems.

Benefits to Clients

  • Reduced risk of failure and improved security of disinfection, developed within a Drinking Water Safety Plan framework
  • Demonstration of security of supply to customers and Regulators, with appropriate audit trails for DWI inspection.
