We have completed multiple years of planning and have identified the opportunity to improve water quality while creating wildlife habitats and new opportunities for education and public open spaces. The expansion of the Water Pollution Control Facility will meet Redmond’s growing needs through a constructed wetland system, the Redmond Wetlands Complex.

The overall site layout, architectural features, and public access areas will be designed to balance the natural landscape as much as possible while still being cost-effective.

The improvements will include:

  • New Operations facilities
  • Primary treatment provided with headworks screening
  • Aerated lagoon system for secondary treatment
  • Lined treatment wetlands for effluent polishing
  • Unlined wetlands for effluent disposal

Once complete, the Redmond Wetlands Complex will treat more than 4.6 million gallons per day of wastewater, while ensuring all DEQ permit requirements are met.


The expansion of the Water Pollution Control Facility will meet Redmond’s growing needs through a constructed wetland system, the Redmond Wetlands Complex.

Constructed wetlands are engineered and managed wetland systems that are increasingly receiving attention for wastewater treatment and reclamation. Constructed wetlands have proven to be a very effective method for the treatment of municipal wastewater. Compared to conventional treatment plants, constructed wetlands are cost-effective and easily operated and maintained while supporting wetland habitat for birds and other wildlife and offering recreational and educational opportunities.

In 2005, Prineville was tasked with upgrading its wastewater treatment facilities. Rather than build a $62 million mechanical plant that would consume a large amount of electricity and chemicals, city leaders opted for a more cost-effective and environmentally sensitive approach.

Completed in 2017, the City’s Crooked River Wetlands project avoided significant rate increases for businesses and citizens with a natural wastewater treatment system that established a 120-acre wetlands complex along the Crooked River. While the complex incorporates effective wastewater treatment — expected to meet the city’s needs through 2040 and beyond — it also serves as an interactive community asset with open spaces, wildlife-watching, and educational kiosks.

The expansion project has multiple community benefits and aligns with Redmond’s 2040 Comprehensive plan and Redmond Vision:


Wastewater can be turned into reusable water.

Reusing water alleviates pressure on freshwater sources and natural systems.


Reusing water can be more cost-effective than developing other alternative supplies.


Because wastewater is renewable, water reuse is the only sustainable source of fresh water.


Water is purified to meet stringent state and federal water quality standards.

Increased environmental and educational opportunities for the Community.
