Wastewater Fees

About Wastewater Fees

All properties connected to the public wastewater system pay wastewater fees. Eugene provides local wastewater collection services, and the Metropolitan Wastewater Management Commission (MWMC), a partnership of Lane County and the cities of Eugene and Springfield, operates the regional wastewater collection and treatment facilities (Eugene Code 6.401-6.471).  

User Fees  

MWMC’s regional wastewater rates are necessary to fund the operation and maintenance of the existing wastewater treatment facilities and implement planned capital improvement projects. The regional wastewater facilities were designed in the late 1970s to serve the community for 20 years.

In 2004, the MWMC adopted a Facilities Plan that identifies cost-effective solutions for the region’s wastewater needs projected through 2025. The MWMC is investing in significant improvements to provide capacity for community growth, avoid raw sewage overflows caused by rainy weather, and meet new, more stringent regulatory requirements to protect the Willamette River. Both user fees and systems development charges will provide resources to support these investments. 

Maintenance and Improvements

The regional wastewater program is complemented by local collection systems and pump stations maintained by the cities of Eugene and Springfield. The increase in Eugene’s local wastewater user fees is necessary to maintain current operating service levels while also funding necessary capital improvements. Both cities are committed to funding capital improvements that will reduce the amount of water entering the collection system during peak wet weather periods.

 Customers pay a combined fee which includes a basic MWMC (regional) flat charge per month and a flow-based fee, calculated on the amount of water used and customer category.  

The City of Eugene adopts and administers the stormwater and wastewater service fees. EWEB acts only as the City’s billing agent per City Charter.

Basic Monthly Fee

A basic MWMC (regional) charge of $14.51 per month.

Flow-based Monthly Fee Schedule

The flow-based fee is the combination of City of Eugene and MWMC (regional) wastewater service rates per 1,000 gallons (1 kgal) of water used. Customer categories are based upon the strength and characteristics of wastewater discharged to the public sewer system.

Wastewater Bills Vary Summer to Winter

Eugene uses a flow-based averaging procedure that acknowledges that some of the water used during summer months (May—November) may not enter the wastewater system. Wastewater charges for these months are based on the previous winter’s average monthly use or on the actual water used, whichever is less. Wastewater charges on bills issued during the winter months (December—April) are based on actual water meter readings. 

Typical Residential Monthly Bill

(Assumes 5,000 gallons monthly usage)
Basic Charge (MWMC) $14.51
Flow-based Charge (MWMC) $14.43
($2.886 x 5 kgal)
Total Regional Fee $28.94
Flow-based Fee (City) $13.61
($2.721 x 5 kgal)
Total Monthly Fee (Regional and City) $42.55
