• PROJECT OVERVIEW

The City of Redmond has significantly grown and changed since it installed its first wastewater treatment facility in 1978. The projected population in Redmond by the end of 2045 is 54,000. The current system can process and treat 2.8 million gallons per day; the current system will need to be expanded to treat the 4.6 million gallons per day required for the projected population growth.

The City is expanding the wastewater facility to meet Redmond’s growing needs and address aging infrastructure concerns.

The City is underway with the design of the expansion of the wastewater facility. The expansion will relocate the City’s main WPCF, currently situated inside City limits, near a residential area at the north end of ‘dry canyon,’ outside City limits where the City currently repurposes and discharges all of Redmond’s treated wastewater effluent and biosolids.

The City is planning improvements needed to protect public health and the environment, address regulatory requirements, prepare for future growth, provide public open space, educational opportunities and provide ancillary benefits.

The primary aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
