📋 Tender Overview
Description: Modification of previous CIP 2018-2027 project E-15. This project was included in the prior CIP at $6 million. The change in budget is due to a modification to the project's scope. As part of the plant's Biological Nutrient Removal process, phosphorous is removed from plant effluent and captured in biosolids. Biosolid supernatant from the lagoons is continuously recycled to the head of the plant, recirculating the phosphorus through the treatment process without reducing it, which has resulted in accumulated concentration of phosphorous. This phosphorous precipitates in pipes, tanks, and pumps forming a crystalline structure called struvite, causing pipe blockages, pump inefficiency, and challenges meeting regulatory effluent limits. This project will implement equipment for removal of phosphorous and protect existing equipment from blockage and service interruption.
