Midway Heights Elementary School Relief Sewer

About the Project

CPS engaged ES&S to prepare an Engineering Report to evaluate future treatment options for the school’s onsite recirculating sand filter (RSF) treatment facility (designed by ES&S in 1999).  The report recommended a new pump station and PVC force main to relieve the onsite facility and convey the flows to an existing gravity sewer that would take flows to the Boone County Regional Sewer District’s (BCRSD) Midway Crossings WWTP.  The report also included the steps required for plant closure to eliminate the school’s MDNR discharge permit.

Project services included topographic & boundary surveys, easement displays, design of 4800-LF of 4-inch SDR26 and 6-inch SDR35 PVC force main, one 8-inch PVC road bore, a package pump station with security fencing, and a 100-LF of 24-inch HDPE storm drainage culvert for a new access drive.  ES&S provided coordination between the school district, BCRSD, and MDNR, provided necessary permits and a SWPP, and prepared materials that assisted CPS with stakeholder outreach, easement acquisition efforts, and elimination of the existing discharge permit.
