Sunriver Wastewater Treatment Plant MBR Upgrade

Upgrades to Sunriver’s existing 1.5 mgd treatment facility included a membrane bioreactor (MBR) and associated biological treatment processes to achieve Class A recycled water standards as defined by the Oregon Revised Statutes. The project also included a new preliminary treatment facility (headworks), upgrades to the existing solids handling processes, disinfection, demolition of existing structures, and odor control facilities. The project was delivered through a CM/GC process.

Parametrix provided planning, alternatives analysis, design, public outreach, CM/GC RFP development, and contractor selection services, and supported the project through construction. Our team also provided specialty engineering services ranging from design of the MBR system to HVAC, odor control, and structural design.

"Parametrix did the design on our wastewater treatment plant upgrades in 2019 and performed the inspections and submittal review during construction. This project has been successful as the change orders have been less than 1% overall, and the schedule is on track to completion before the contract date. We have used Parametrix for other design and construction projects since the plant upgrades project, and we will continue to do so on future projects. I would use them for any and all water and wastewater projects as they have a great team of engineers.”
