Q: What do my monthly sewer service charges pay for?

A: The Regional Water Pollution Control Facility (WPCF) is supported by the fees paid by  residential, commercial, and industrial rate payers. Your monthly service charges pay for the maintenance and operation of the system, upgrades to the treatment processes, and employee costs.

Q: Why is my sewer bill higher than my water bill?

A: Treating wastewater is much more expensive than treating drinking water. Your wastewater bill amount is determined by the amount of water that you use.
 
Q: What does a wastewater treatment plant do?

A: Treatment plants remove solids and other pollutants from wastewater. This treated water can then be safely discharged to the environment. This same process occurs in nature. Treatment plants enhance this natural process and speed it up to treat larger volumes of wastewater in a shorter period of time. Treatment includes physical, biological and chemical processes to clean the    water.

Q: Where does the water go once it is treated?

A: The WPCF treats wastewater collected from the cities of Eugene and Springfield and cleans it before it is discharge to the Willamette River. The biosolids are removed, treated and beneficially reused. Some reclaimed water is also used for irrigation and treatment plant processes.

Q: Who runs the wastewater treatment plant? 

A: Highly trained, experienced, State-certified treatment plant operators employed by the City of Eugene are on duty 24 hours a day, every day, to direct treatment plant processes and to react quickly to any unusual events. Much of the treatment process is highly automated and requires a great deal of technical expertise.

Q: How reliable is the treatment facility? 

A: Reliability at the Wastewater Pollution Control Facility is very high. Critical treatment processes are designed with redundant equipment, which means that if a mechanical or electrical component fails, a backup system is available to take its place. Mechanical and electrical staff are on-call 24 hours a day in case of a failure that requires immediate assistance.

Q: How is the quality of treated wastewater ensured? 

A: Our on-site monitoring provides information and records data on wastewater quality around the clock. Samples are also collected and analyzed in our on-site, State-certified laboratory. This water quality information is continually assessed to ensure permit compliance and protection of the environment

Q: Who regulates the Wastewater Treatment Plant?

A: The Oregon Department of Environmental Quality is charged with implementing state and federal rules governing the operation of wastewater treatment plants.  As such, the DEQ has issued a National Pollutant Discharge Elimination System (NPDES) Permit (number 100980) for the Eugene/Springfield Water Pollution Control Facility. The permit describes conditions and limitations to ensure public health and safety and protection of the environment.
