The Water and Wastewater Treatment Experts Since 1988

Founded in 1988 in Mobile, Alabama, by Frank and Hope McFadden, McFadden Engineering brings more than a century of combined experience in civil and environmental engineering to the Southeastern United States and beyond. As a family-owned and operated business for nearly 40 years, McFadden Engineering has always made customer service a top priority, building client relationships and finding solutions to the challenging engineering problems.

What began as a small team focused on local engineering projects has grown into a robust team of engineers, geologists and staff with jobs across the Southeast and spreading to the East Coast and Midwest. Additionally, a particular focus on water and wastewater treatment led to the team’s development of OxyShark®, a patented aerobic wastewater treatment system utilizing high-purity oxygen to treat domestic, commercial and industrial wastewater – a solution for clients who need treatment capacity beyond a conventional design.

From the beginning, we have worked closely with the U.S. Environmental Protection Agency (EPA), the U.S. Geological Survey (USGS) and many other local, state and federal agencies to ensure our work exceeds expectations on the highest levels.

McFadden Engineering continues to grow, expand and innovate while ushering in a new generation of leadership as it approaches its fourth decade of business.
