As committed to in the 25 Year Environment Plan Defra will be working with industry to consider which measures are most cost-effective to reduce water demand. Future policy on the Water Technology List is therefore under review. No new applications will be considered during this time. We hope to provide updated information in December 2018.
The Water Technology List has just undergone a total refresh and therefore represents the most efficient water technologies to date. The list will therefore remain static until the review is complete, and decisions made against those options available.
