Water Quality

Willamette River

The MWMC takes pride in being responsible caretakers to clean the community's wastewater. The treatment processes protect our community, downstream users, and the Willamette River ecosystem by consistently removing more than 95 percent of pollutants. We strive to produce effluent (cleaned wastewater) that falls under the maximum allowable limits for ammonia, total suspended solids, carbonaceous biochemical oxygen demand, and all of the many other parameters defined in our permit.
