For tens of thousands of people across metro Detroit, this past weekend wasn’t spent relaxing. It was spent in the dark, listening to 70-mile-per-hour wind gusts. Others were likely watching the water line creep up in their basements after days of rain.

When we talk about environmental risk, we’re talking about the collision between volatile weather, intensified by human-caused climate change, and fragile, aging infrastructure. It is the risk your lights won’t stay on, your basement won’t stay dry, and your utility bills will keep rising.

Nearly 95,000 households lost power in this latest storm. While many of the lights are back on, the frustration hasn’t dimmed, especially since DTE Energy’s $242 million rate hike just went into effect earlier this month.

Today marks the start of Severe Weather Awareness Week. Governor Gretchen Whitmer is urging you to “know your plan.” But for many metro Detroiters, that plan is at the mercy of a grid and a regional geography that feels fragile. 

To help us look past the downed limbs and into the systems that are failing, Nicholas Schroeck joined Robyn Vincent on The Metro. Schroeck is the dean of the University of Detroit Mercy’s School of Law and a leading expert on environmental policy.

The Great Lakes Water Authority has started building a new tunnel in southwest Detroit. The project will divert excess stormwater from a large sewer line along the Rouge River to a retention and treatment basin nearby.

Potential to address a longstanding problem

GLWA Chief Operating Officer Navid Mehram says the tunnel will reduce the risk of flooding. Additionally, it should mean fewer basement sewage backups during heavy rain. “We’re making an investment in our existing system by rerouting some flows, so that we can leverage an existing facility that wasn’t receiving all the flow it can treat,” Mehram says.

The tunnel will be almost 4,000 feet long and several feet wide. Nehram says GLWA expects to finish the job in 2028. “Our projects are very large,” he says. “This is a tunneling project, which is extremely complicated.” Besides reducing sewage backups, Mehram says the project will also make the system more resilient to heavy rain. “This not only provides us with water quality improvements along the Rouge River, but it can also provide a backup for our Water Resource Recovery Facility,” he says.

Who’s paying for it?

The project will cost $87 million. Mehram says GLWA will use both government grants and sewer rate revenues to pay for it. He says it will not increase customers’ bills.
