From the perspective of drinking water UV disinfection regulations, 2006 was a landmark year. It saw the release of both a new standard in Europe, the DVGW worksheet W294, and a new guideline in the US, the USEPA Ultraviolet Disinfection Guidance Manual. Whilst both seek to provide stakeholders with guidance on planning, operating and validating UV systems for drinking water applications, they take quite different approaches.

This paper outlines the approach taken by these two agencies and details the key similarities and differences.
