Inside the Lake Vermillion Dam Restoration

Inside the Lake Vermillion Dam Restoration

Sure, the weather is getting colder, and it’s the time of year when we all spend a little more time indoors. But did you know that our Aqua Illinois team has entered the initial stages of a dam restoration project in Danville, Illinois to improve the reliability and quality of the water in Lake Vermilion?

As the Aqua Illinois team prepares for excavation, Bob Ervin, director of operations for Illinois, spoke with us to dig a little deeper into what exactly this major renovation project means for Danville, Illinois, and the surrounding area.

Why restore the dam?

While we regularly complete routine maintenance work on all of our systems, including the Lake Vermilion Dam, Ervin says that this specific renovation “will ensure a reliable water source for residents of Danville and Vermilion County for generations to come.”

Ervin went on to explain that the dam “creates a man-made impoundment of water, which is critical to meeting the water demands of the Danville area” and that the renovation project will continue to allow the water within the dam to exceed the EPA’s Safe Drinking Water Act regulations.

What’s the status?

In preparation for the construction phase, crew members set up cranes, boats, air compressors, generators, ramps, barges, and more. After this initial stage, the project moved into construction, which  entailed the removal and replacement of six of the 10 tainter gates in 2019. The remaining four tainter gates and the high-level sluice gate will be completed in 2020.

To complete the renovation, workers will use anchoring to perform post-tension support work, followed by a teardown, clean up and removal of all worksite equipment and materials. We’re dedicated to keeping the Danville service area clean and functional, and we’re committed to minimizing any potential inconveniences to local customers.

What about customers who want to use the lake recreationally?

During construction, our crews reduce potential disruptions by installing a high visibility safety float barrier on the lake from shoreline to shoreline, stretching 650 feet in length with orange buoys as markers. This safety measure is an effort to protect those who wish to use the lake recreationally over the course of the dam restoration.

Aqua Illinois recognizes Lake Vermilion’s role as the primary water source for Danville and Vermilion County as well as its many recreational purposes. Ervin ensures that Aqua will provide regular communications to the public, including residents who live along Wilkin Road, which leads to the dam site, and to residents living around the lake itself.

Whether we’re working in Illinois or any of the eight states we serve, we’re dedicated to improving our infrastructure systems on a continual basis in order to provide safe, reliable water to all of our customers.
