Sewer rates

Marysville’s sewer collection system maintains 240 miles of sewer lines and discharges about 6 million gallons of wastewater per day for more than 22,000 customers in and around Marysville. Our Wastewater Treatment Plant collects wastewater and treats it prior to discharge, meeting or exceeding State of Washington standards as set by the Department of Ecology.

Residential sewer bills are a flat rate based on housing type.
