Water Department

 

The St. Louis water system consists of 35 miles of water mains ranging in size from 4 inch to 12 inch. Five wells from 130 to 270 feet deep, drilled between 1930 and 1990 furnish water for the community. Ongoing testing continues to confirm a high quality, reliable water supply for St. Louis.  One non regulated contaminant, p-CBSA has been found in St. Louis' water.  This chemical is neither hazardous nor carcinogenic.  The City and EPA continue to monitor detection levels for p-CBSA, which have decreased from initial levels.  Tritium tests have shown the source aquifers to be “protected” from recharge from the Pine River or shallow sands. The Federally mandated Consumer Confidence Report (CCR) has been published yearly since 1998. Testing continues to confirm a safe water supply for St. Louis water supply consumers.  Consumer Confidence Reports are mailed yearly to all water consumers. Copies of each year's CCR are available upon request at City Hall or on our web page.

System water pressure is maintained by one 500,000 gallon elevated water storage tower at 55-65 psi. Fire service is excellent as the system has over 260 fire hydrants with good pressure and flow volume throughout. The City's current daily maximum well pumping capacity is in excess of 3.0 million gallons. During 2010, the daily average production was 845,000 gallons. Total yearly water production for 2010 was approximately 307,715,000 gallons.  
 
The City has completed a 5-year master plan for the Water system, which included plans for the replacement and addition of water main valves on M-46, Hazel, E. State, and Franklin Streets.  Plans are undeway to complete the rebuild of S.t Franklin and Maple Streets which will include all underground infrastructure.

Wastewater Department

 
The St. Louis Wastewater Plant is a $15,000,000.00 facility. Built originally in 1954 as a primary treatment plant it was expanded in 1978-80 and again in 1998-2001.  The plant today is a state of the art, tertiary-biological-chemical-sand filter system.  Designed to treat a maximum of 5.0 gallons per day, the plant has a daily average design flow of 1.6 MG. Currently the plant accepts wastewater from the City as well as two adjoining townships, Bethany and Pine River. Flows in 2010 averaged 1.036 MGD. Wastewater is pumped to the plant via five pump stations; two from the townships, two City and one which handles two of the Prisons.

The plant processes consist of screenings and grit removal, primary clarification, 12 RBC's (rotating biological contractors) for ammonia and BOD removal, secondary clarification and chemical phosphorus removal, chlorination and de-chlorination (both chemical and pond detention), and lastly, continuous backwash sand filtration. Three storage tanks allow storage of anaeobic digested waste solids. Digested biosolids are stored prior to land application in the fall or spring months. Total storage volume is 780,000 gallons.

Since completion of construction in 2001 treatment efficiencies of between 95-99% have been seen for all monitored parameters.

The staff of PJ McGillis, Alan Strouse, Greg Austin and can be reached during normal business hoursat the plant at 404 E. Prospect. Office hours are Monday through Friday 7:00 a.m. - 5:00 p.m. or call (989) 681-3567 or by E-mail at wwtp@stlouismi.com.
