- Omaha is among more than 772 cities across the country required to reduce the number of combined sewer overflows into area rivers and streams.
- The CSO Program is an unfunded, federal mandate which requires Omaha to meet federal clean water standards by October 2027.
- The Program is estimated to cost $2 billion (2013 dollars) for the required improvements, paid for by all residential, commercial and industrial ratepayers in the Omaha metro and suburban communities who use the regional sewer system.
- Five types of solutions will be employed to meet the requirements: sewer separation, high rate treatment plants, stormwater conveyance sewer, deep tunnel and underground storage tanks.
