*APWA 2003 Environmental Public Works Project of the Year*

In the early 1990’s the City of St. Charles annexed an area on the west side of the City.  As a means of providing water to the newly acquired area, the City proposed a new well and iron removal facility to be constructed to provide additional capacity to this Outer Service Area.  The improvements included the drilling and development of a new shallow sand and gravel well in the St. Charles Aquifer.  The well drilling was performed as a separate contract to expedite the project and to allow testing prior to commencing with the final design of the well pump and water treatment facility. 

Trotter and Associates provided the second phase of the project which consisted of site improvements, the installation of the well pump and the construction of the water treatment facility.  The project which began in October of 2001 included the installation of two Greensand pressurized filters proven effective for oxidation and removal or iron, manganese and hydrogen sulfide.  Together, the filters can produce up to 2.3 million gallons/day of treated water for domestic, commercial and fire suppression users.   

The water treatment facility includes a laboratory,  washroom, electrical room, mechanical room, chlorination room, chemical feed room, filtration room and two backwash holding tanks located under the floor of the work room/garage.  The project scope also included SCADA improvements that allow the continuous monitoring of the water treatment facility from the Water Department’s offices located in the Public Works Facility across town.  Site improvements included paving, landscaping, utilities and stormwater management.
