Davy Engineering Co. Davy Engineering Co. offers consulting engineering and laboratory (Davy Laboratories) services in Wi Founded in 1929 by Frank J. Davy, Davy Engineering Co.

is today the oldest and largest consulting engineering firm in the La Crosse area. The firm initially provided services
to the City of La Crosse and nearby communities for local streets, highways, bridges, and sewer and water systems. In 1938, Frank's son, Philip S. Davy, joined the firm. As a result, the company name changed to Frank J. Davy and Son, with services directed more toward water supply, water treatment and wastewater collection and treatment. In the 1940s, the firm name was changed to Davy Engineering Co. Philip's son, Michael F. Davy, a graduate of the University of Wisconsin-Madison, joined the company in 1969 and became the third generation of the Davy family to lead the firm. In 1975, the company established Davy Laboratories to provide municipal and industrial clients with cost-effective analyses of their water supply and wastewater discharges. In addition, the laboratory provided support for the engineering division in designing and evaluating performance of water and wastewater treatment facilities and addressing water quality issues. Michael's brother, Thomas H. Davy, joined the firm as office manager in 1981. In 1994, Michael's son, Mark S. Davy, the fourth-generation family member, joined the firm as project engineer after graduating with a degree in civil and environmental engineering from the University of Wisconsin-Madison. offers engineering services in Wisconsin, Minnesota, and Iowa.

Thanks to the Kohler Foundation for supporting an investment in the engineering education critical to our business.

With the support from a $4 million investment from Kohler Foundation, Inc., the future of environmental engineering education at University of Wisconsin-Madison is set to reach new heights.

The gift will support a prominent undergraduate environmental engineering teaching laboratory in the new Phillip A. Levy Engineering Center, creating enriched hands-on learning opportunities and strengthening Wisconsin's position as a center for innovation.

This investment builds on a longstanding partnership between KOHLER, the Kohler Foundation, and UW–Madison, advancing sustainability and educational excellence across Wisconsin and beyond.

The Wisconsin DNR has been informed by Wisconsin Emergency Management that Wisconsin drinking water and wastewater systems are at severe risk of cyber-attacks. The following statement and Recommended Actions has been issued to Wisconsin's public drinking water and wastewater systems:

"On July 27, 2026, staff at the Wisconsin Statewide Intelligence Center (WSIC) confirmed that multiple Programmable Logic Controllers (PLCs) located at systems within Wisconsin have had communication with a list of malicious IP addresses. This leads us to believe that the cyber threat is ongoing in Wisconsin and requires immediate action to prevent potentially serious impacts to our systems.
Recommended Actions: The Wisconsin Department of Natural Resources (DNR) strongly recommends that all systems do the following:
1. Closely review the CISA advisory to determine if any systems use PLCs from the listed manufacturers (Rockwell Automation/Allen-Bradley, Schneider Electric, Siemens and other branded/manufactured PLCs).
2. Remove PLCs from direct internet exposure via secure gateway and firewall.
3. Ensure that ports 44818, 2222, 102 and 502 are inaccessible from remote connections.
4. Ensure all operational PLCs are supported by the vendor and have received current security updates.
5. Report any suspected or confirmed incidents to WSIC’s Cyber Incident Reporting Form. Please make sure to list any potentially malicious IP addresses that had communication with your PLCs.
Please contact WSIC at [email protected] or (608) 242-5393 for any questions about the advisory or reporting."

Let us know if we can be of any assistance in communicating with your system providers.
