About DEC, Now a Part of Gannett Fleming

We’ve always been more than an engineering firm. We team with clients and others to find innovative solutions to make communities better. Through the decades, we’ve partnered to provide safe water and sewer systems, address subsidence, and identify ways to fund mass transit and highway projects. 


Making Communities Better  

In the 1950s-60s DEC played a leadership role in addressing public health concerns in Houston by establishing entities to fund residential water and sewer services, including for Acres Homes, a historic African American community established during World War I. That commitment continues today.
