Phosphorus Contributions from WwTW Discharges to Watercourses and their Long Term Impacts Relative to Other Sources
The Water Industry is a major contributor to phosphorus discharges to the environment. By 2015 there will be over 650 wastewater treatment works (WwTW) in the UK with phosphorus consent levels driven by a number of EU Directives, including the Water Framework Directive. There has been considerable uncertainty with regards to derivation of the phosphorus environmental quality standard, which was initially derived as a supporting parameter to describe diatom ecological quality.
This project provides an increased understanding of the linkages between phosphorus speciation and ecology within the aquatic environment; the work undertaken included a combination of literature reviews, data collection and modelling using the Hampshire River Avon as a case study catchment.
The links between phosphorus and ecological status, as well as possible future permitting options, were assessed. Recommendations on how best the water industry can enter into discussions with the Environment Agency, to prevent incurring disproportionate costs with regards to phosphorus discharge reductions, have been made.
