WISs and IGNs

Current Water Industry Specifications (WISs) and Information and Guidance Notes (IGNs) are managed by Water UK and available here.

Water Industry Specifications (WISs) are prepared by the UK water industry for the specification and purchase of products used in the industry. They generally cover products for which there is no suitable European or British standard.

Information & Guidance Notes (IGNs) are used to provide additional guidance to a WIS or provide interpretation and additional information to European or British standards.
