Severn Trent Services Comply with DWI
Drinking Water Regulatory Requirements
Severn Trent Services successfully comply with the regulatory requirements for the laboratory sampling and reporting of results for drinking water, as specified by the Drinking Water Inspectorate (DWI).
The DWI recently published an information letter to water companies and local authorities in England and Wales in relation to drinking water, laboratory sampling and reporting of results meeting regulatory requirements. All laboratories carrying out analysis of drinking water for regulatory purposes must obtain and maintain UKAS accreditation equivalent to ISO17025: 2005.
Severn Trent Services’ laboratories in Coventry, Bridgend and Wakefield are all accredited by UKAS to ISO 17025: 2005. The laboratories also hold the higher-level accreditation, the Drinking Water Testing Scheme (DWTS) for the microbiological and chemical parameters specified in the Regulations. The three sites will not be subject to additional audits by the DWI which are required for laboratories not holding DWTS approval.
In order to comply with the Water Supply (Water Quality) Regulations and the Private Water Supplies Regulations, samples must be presented for analysis only to a laboratory that has the appropriate quality systems in place as set out in the regulations and in the Inspectorate’s Guidance on the Regulations.
