Biosolids Digester Facilities: Current Conditions Existing facility built in 1952 Does not meet current operational and maintenance, structural, and seismic requirements Old Technology Existing facility cannot produce Class A Biosolids (which is the treatment level that will be required in the near future) Significant source of odor to the community The most labor intensive facility at the plant
Biosolids Digester Facilities: Project Objectives Modern Treatment Facilities Reliably meet SSIP Goals and Levels of Service Meet present and projected regulatory requirements Produce Class A biosolids for beneficial reuse Beneficially reuse 100% of the Biosolids and Biogas Meet the needs of stakeholders Transform SEP into a Community Asset Be a contribution to the surrounding community Minimize odors, noise and traffic Promote Jobs and Training
