What is the TWI?

The Plan

The goal of the Toledo Waterways Initiative (TWI) is to clean our waterways and reduce sewage overflows through wastewater storage, sewer separation and improved wastewater treatment. These solutions involve over 45 separate projects encompassing 48 square miles over the course of 18 years, at a total cost of $527 million.

Among the major projects completed or planned:

Improvements to the Bay View Wastewater Treatment Plant to increase wet-weather capacity and storage to prevent overflows during storms. There have been no untreated bypasses at the plant since the improvements were completed in 2006.

  • $135.1 million

Elimination of sanitary sewer discharges at key locations, including Arlington Avenue, Detroit Avenue, Fernhill Road, Heatherdowns Boulevard, Parkside Boulevard, Point Place and River Road.

  • $70.6 million

Implementation of a long-term control plan for combined sewer overflows (CSOs).

  • $321.8 million
