Stormwater Management and POL System Improvements

Location: Joliet , IL, Twinsburg, OH, and Monclova, OH
Client: USACE Kansas City District - 88th Regional Support Command
Project Description

The U.S. Army Corps of Engineers (USACE) Kansas City District issued T.O. 0006 under Contract W912DQ-13-D-3024 to CTI-EMR LLC, a joint venture between CTI and Associates, Inc (CTI) and EMR, Inc. CTI-EMR, LLC served as Design Engineer and Prime Contractor for the storm water runoff and drainage improvements at 3 sites: Joliet Training Center in Elwood, Illinois; Twinsburg USARC in Twinsburg, Ohio; and Toledo Area Memorial USARC in Monclova, Ohio.

The Scope of Work (SOW) at Joliet Training Center consisted of removal of the facility’s existing exterior wash rack system due to lack of use and to address compliance issues. Included in the scope was demolition and removal of 10,000 SF of concrete pavement, 4 overhead wash towers/sprayers and associated components, 2 below-grade open air concrete basins, a sewer lift station, and an enclosed pump house. Total C&DD debris removed from the site was over 1,200 tons of material. Site work was performed between August 25 and September 19, 2014.

CTI’s SOW at Twinsburg USARC consisted of removal and replacement of the facility’s existing oil-water separator (OWS) system due to operational inefficiency, maintenance hazards, and overall inadequate capabilities. Included in the scope was relocation of existing sanitary sewer piping, removal of the existing OWS tank and concrete vault, installation of a new 1,000-gallon steel OWS tank and associated electrical components, and placement of concrete and asphalt pavement. Site work was performed between November 12 and 26, 2014.

CTI’s SOW at Monclova USARC consisted of demolition, removal and replacement of the facility’s existing dual chambered oil-water separator (OWS) system due to operational inefficiency, maintenance constraints, and overall inadequate capabilities. Included in the scope was removal and replacement of 1,100 SF of heavy-duty concrete pavement, removal of the existing OWS tank, and installation of a new 2,000-gallon steel OWS and associated electrical components. Discovery of deeper than anticipated existing utility connections forced CTI to excavate deeper and install a well-point dewatering system to complete the tank installation. Site work was performed between May 5 and June 2, 2014.

Project Highlights
  • Demolition and removal of existing oil-water separators (OWS) and wash rack system
  • Installation of new OWS tanks and associated piping and electrical systems
  • High groundwater conditions required temporary well-point dewatering system
