Inventory and Analysis
<br />Sanitary Sewer
<br />Elk River's desired future land use pattern must be
<br />tied closely with a cost - effective wastewater service
<br />strategy. The City must be certain in determining the
<br />pattern of sanitary sewer interceptors, lift stations,
<br />and force mains to complete its development pattern.
<br />Moreover, the City must ensure that costs of these
<br />improvements are equitably distributed and services
<br />are provided in a planned, phased sequence that
<br />promotes development.
<br />The sanitary sewer collection system in the City of
<br />Elk River includes over 77 miles of lines. As a result,
<br />21 lift stations are needed to transport sewage to
<br />a wastewater treatment facility that the City of Elk
<br />River owns and operates that serves the residents of
<br />Elk River as well as commercial and industrial users
<br />located within the community. The plant is located
<br />between Highway 169 and the rail line, north of the
<br />Elk River Comprehensive Plan
<br />Great River Energy plant and has been in operation
<br />since 1977 with several upgrades since. Wastewater
<br />improvements since 2004 include upgrades to the
<br />wastewater treatment facility in 2005, sand filter
<br />upgrades in 2006, and upgrades to various lift
<br />stations every year.
<br />In February 2013, a Wastewater Treatment Facility
<br />Plan was completed to evaluate the capacity of the
<br />existing facility and the ability to reliably achieve
<br />the reduced effluent limits at design flows and loads
<br />and to develop a plan for future plant modifications.
<br />As improvements to the facility are presented, the
<br />City should follow the recommendations of the
<br />Wastewater Treatment Facility Plan.
<br />The current plant has a maximum treatment capacity
<br />of approximately 2,200,000 gallons per day. On June
<br />23, 2012 the highest daily flow was recorded at
<br />1,930,000 gallons. Table 8 -A: Wastewater Treatment
<br />Facility Average Daily Flows 2006 -2012 shows the
<br />changes in annual daily flow since 2006.
