Title: Sewage treatment works remedial strategy : phase 2 report
Author: National Rivers Authority Welsh Region
Document Type: Monograph
Abstract:
The objective of this strategy is to identify those Dwr Cymru Welsh Water (DCWW) Sewage Treatment Works (STWs) which are having adverse environmental impacts on receiving waters and to identify priorities for remedial action. Biological, aesthetic and water
quality criteria have been developed to assess and prioritise the impact of 882 STWs operated by DCWW in the Welsh Region. The strategy has been developed over two phases. Phase 1 has already been reported (May 1992) and this report covers Phase 2 during which assessment of all STWs has been completed and the final ranking of STWs for remedial action has been determined. 593 works have been assessed as having no environmental impact (category A), 268 works have been assessed as having an environmental impact (category B) and 21 works have been abandoned since the strategy was begun.
