1. Hydraulic Model:

Hydrological - generates dry weather flow & wet weather inflow

  • Winter water billing records ​
  • 2010 census
  • Subcatchment delineation​
  • Flow monitoring data – RJN 2013

Physical elements of the conveyance system – sewer, manholes, lift station

  • 32 miles of gravity sewer​
  • 274 manholes
  • Lift station: Ela, Deerfield Road, and Portwine Road were explicitly modeled
  • Des Plaines River Water Reclamation Faciliy

2. Model Calibration:

Calibration events​

  • April and June 2013
