Waterway Protection Tunnel

A new solution to an environmental challenge

Before MSD’s Consent Decree work began, more than 5 billion gallons of rainwater and wastewater overflowed into our waterways each year. MSD’s Waterway Protection Tunnel is an innovative way to store even more of this overflow of rainwater and wastewater underground until it can be pumped to a wastewater treatment facility, cleaned and released to the Ohio River.

The tunnel is a $201 million project now underway and planned to be operational in 2022. It is one part of MSD’s $1.15 billion Consent Decree to reduce sewer overflows.
