The City of Toledo is Reducing CSO Discharges

The City of Toledo is reducing both the frequency and volume of Combined Sewer Overflows (CSOs) through the Toledo Waterways Initiative (TWI).

When TWI is complete in 2020, we will have an 80% reduction in combined sewer overflow volume, resulting in 650 million gallons less pollution on average from entering the waterways each year.

The public will be provided with supplemental information within seven days after the conclusion of a documented CSO event.

The City will provide a summary of the previous year’s CSO discharges by May 1 each year.
