Regional Wastewater Control Facility Modifications Project

The Regional Wastewater Control Facility (RWCF) was constructed over 60 years ago, with some processes reconstructed within the last 20 years. Equipment and infrastructure have outlived their useful life. Modifications to the RWCF are required to meet new State discharge requirements, extend the useful life of existing facilities, improve working conditions for facility staff, and to implement components of the City’s Capital Improvement and Energy Management Plan (CIEMP).


The proposed RWCF modifications consist of demolition of certain treatment process components and buildings, rehabilitation and repurposing of some existing components and buildings, and construction of new treatment process components and buildings. Existing RWCF facilities would remain in operation during construction of new and rehabilitated facilities to ensure continual wastewater treatment services. The improvements would not provide additional wastewater treatment capacity at the RWCF beyond the existing permitted discharge capacity (55 million gallons per day, average dry weather flow).


The estimated project cost is $150-$170 million and is in preliminary design stages. Funding for the CIEMP was included in the 2010 Wastewater Rate Study and the approved phased rate increases.
