Environmental Impact Assessment to Compare the Benefits of Achieving Tight BOD Standards Versus Increase in Whole Lifecycle Carbon
There has been a drive by regulators to improve the quality of the aquatic environment, most recently in response to the Water Framework Directive. This has often been achieved through setting tighter permit limits on final effluent discharges from WwTW. Achievement of these tighter limits has been through increasing the degree of wastewater treatment, normally resulting in the use of higher carbon-impact treatment processes.
This project investigated the balance between the benefits to the aquatic environment from achieving tighter BOD standards and the costs, in terms of increasing carbon emissions as well as the impact on customers through increased bills. It also examined whether tighter BOD standards are an effective means of achieving water quality improvements, in terms of outcome and value for money. This report is intended to inform the debate with regulators (economic and environmental) with regard to setting future WwTW permits and price limits.
The report includes a spreadsheet Decision Support Tool that can be used to assess the impact of tighter BOD standards on river quality, carbon emissions and treatment costs.
