The provision of a sewage treatment works will be instrumental in meeting a significant number of environmental objectives, in particular RSTS2, UNESCO Biosphere Status, and future environmental objectives detailed within 'Our Island Plan'. The delivery of modern sewage treatment facilities for one of the largest towns on the Island and the associated water quality improvements carries significant weight, particularly given the nationally identified need to deliver these facilities. The benefits of the development significantly and demonstrably outweigh the identified harm and it is therefore recommended that planning permission be approved. Date of Issue: 16th July 2024
