Oxidation ponds (OPs) are a natural wastewater treatment system that have been used internationally for their low maintenance, cost, and technology characteristics. The City of Arcata has relied on the performance of their two-oxidation ponds for the past 50 years to meet National Pollutant Discharge Elimination System (NPDES) discharge permit requirements. However, during specific times of the year and after decades of operation and minimal maintenance, these oxidation ponds serve as a source of solids and nitrogen that create stress for downstream components of the system. As bio solids have accumulated, the hydraulics of the OPs have deteriorated and the …
