Methodologies for Catchment Based Consents
The project investigated how best to identify where, when and how wastewate treatment should be improved; and, how future performance should be monitored. A SIMCAT model was used to examine the potential benefits of catchment based consenting to the Water Industry. The results from twenty two scenarios, focused on changes to Water Industry assets, were compared in terms of WwTWs consents, overall catchment loads, and the length of river passing WFD standards. A key conclusion was that achieving full compliance with these standards would not be possible by consent tightening alone, nor would it be cost-effective. A catchment modelling approach to consenting is likely to produce less onerous consents that a single site approach. The full benefits of a catchment modelling approach will only be achieved by linking water industry asset management strategies, natural catchment characteristics and the potentil benefits of controls on other sources of pollution. It was recommended that a further range of model scenarios should be tested to show the wider benefits of an integrated catchment consenting approach and to illustrate 'best practice' for catchment modelling.
