The Eagle River Water and Sanitation District (ERWSD) is in a unique situation that facilitates a close integrated planning approach among its facilities. This case study illustrates an approach and takeaways that are relevant for other WRRFs who are in the process of finding cost-effective paths towards compliance with upcoming numerical nutrient criteria, particularly the opportunities for an integrated planning strategy among facilities located in the same watershed. Nutrient trading and flow diversion between facilities to handle peak conditions can balance financial impact to facilities and rate payers, and reduce the risk of permit violations. Based on this planning approach, the project team developed a comprehensive and innovative plan that benefits the instream water quality and balances the availability of ERWSD resources with the financial impact to their rate payers.
