John Burns Construction Company successfully completed the construction of a one million gallon underground concrete storage tank.

• Construction of a one million gallon underground concrete storage tank.  The purpose of the tank is to allow for temporary storage of sewage discharge during periods when the Flag Creek District is unable to handle the volume.  The stored sewage would then be pumped back into the Flag Creek system during periods of low volume for further treatment. 

• A 1200 SF screening building was constructed to house all the pollution control equipment required to screen and disinfect the sewage prior to entering the underground storage tank which included a mechanical bar screen, screening washer compactor, odor control center, sodium hypochlorite system and break tank. 

• The CSO facility was equipped with a supervisory control and data acquisition (SCADA) system which will allow the facility to be controlled and monitored from a remote location. 

• Over 1600’ of storm sewer was installed through Veeck Park and down Highland Road to separate the aging combined sewers in Hinsdale and alleviate the flooding issues around the Highland Road area.  A diversion structure and screen chamber was constructed at another location.
