Wastewater Department

Sewer Plant History



The City of Canyonville provides wastewater collection
and treatment services to the residents and businesses
within the City's urban growth boundary (UGB).  By
consistently and effectively providing these service, the
City protects the water quality and supports the
beneficial used of the South Umpqua River.  The major
elements of the City's wastewater infrastructure includes
the sanitary collection system and the wastewater
treatment plant (WWTP).  The age and condition of the
collection system varies as it was installed over time to
serve the population growth.

While the WWTP has generally served the City well over
the years, many components have reached the end of
their useful life.  In addition, the existing plant does not
have adequate capacity to accommodate planned growth,
nor can it comply with anticipated effluent quality limits.

The City has received funding for Phase 1 construction
consisting of a new head works, influent pump station,
repair to the existing outfall, and chemical feed for
phosphorus and de-chlorination system.  Construction
began in May of 2014 and was completed January 2015.

The City has received funding for Phase 2
construction which we hope to begin by the summer of
2018.  Phase 2 will provide a new secondary treatment
system which will treat the effluent that goes into the
South Umpqua River to almost drinking quality.  After
Phase 2 is completed the City will be in compliance with
all current Department of Environmental Quality
regulations for the sewer plant.
