  • +/- 2,800 linear feet of 16-inch force main
  • +/- 20 linear feet of 8-inch gravity sanitary sewer
  • +/- 30 linear feet of 10-inch gravity sanitary sewer
  • +/- 175 linear feet of 12-inch sanitary sewer
  • +/- 100 linear feet of 15-inch gravity sewer
  • +/- 150 linear feet of 24-inch gravity sanitary sewer

 

  • +/- 50 linear feet of 36-inch gravity sanitary sewer
  • +/- 2,600 linear feet of 42-inch gravity sewer
  • +/- 1,400 linear feet of 60-inch gravity sanitary sewer
  • +/- 75 linear feet of 4-inch water main
