The Public Works Services department is directly responsible for the operation and maintenance of the wastewater level II collection system consisting of:
- 15 miles of sanitary sewer main lines
- 30,000 feet of sanitary sewer service lines
- 253 sanitary sewer manholes
- Two permanent and one temporary lift station with an additional station planned for construction in 2010.
The wastewater treatment plant is a tertiary sewage level III treatment plant.
The plant treats inflow from the City of Myrtle Creek and the City’s Urban Growth Boundary Area serviced by the Tri-City Water and Sanitary Authority.
The plant was designed to treat average dry weather flows in summer of 1.8 Million Gallons per Day (MGD), and 2.4 MGD average wet weather flows in winter and has a peak maximum design flow capacity of 7.03 MGD. The treatment plant is operated by the State of Oregon Wastewater Treatment Plant certified operators seven days per week, year round.
The treatment of wastewater or sewage in a wastewater treatment plant produces a byproduct called biosolids or sludge.
The City utilizes a Fenton Dryer to treat our biosolids. The dryer dehydrates and sanitizes wastewater solids in an enclosed chamber using indirect thermal technology.
The result is clean, light, granular Class A biosolids that are safe and beneficial for agricultural, horticultural, municipal and domestic use — truly putting waste to work.
Our bio-solids operation produces a class A Exceptional Quality (E.Q.) bio-solids product.
We produce over 108 Dry Tons of biosolids annually with a Fenton natural gas biosolids dryer which dries dewatered biosolids from the centrifuge prior to land disposal.
Dryer runs average solids concentration is around 97%. Fecal Coliform results prove the finished biosolids to be virtually pathogen free.
