  • Every year millions of gallons of combined sewage, stormwater, and debris overflow to the Wabash River.
  • The overflows cause increased E. coli readings and other pollution to the river.
  • The City of Terre Haute is undertaking a program to reduce the number of overflows to the river.
  • The goal of the CSO Reduction Program is to have a cleaner city, resulting in a cleaner river.
