Who We Are

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.

A Legacy of Innovation

Founder and innovator Joseph B. Dannenbaum developed and patented the energy-efficient solar aerobic wastewater treatment process in the 1950s. His son, Jim Dannenbaum, now honorary chairman, served as president for more than 50 years, a period of remarkable growth for the company.

Making Communities Better 

In the 1950s-‘60s the company 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.

In the 1970s, Dannenbaum Engineering addressed regional subsidence issues by working with Gulf Coast Waste Disposal Authority and others, which led to state legislation establishing the Harris-Galveston Coastal Subsidence District.

In the 1980s Dannenbaum Engineering worked with municipal utility districts and others to begin the formation of the West Harris County Regional Water Authority, resulting in more than $1 billion in new infrastructure to provide surface water to up to 750,000 people.

Looking To The Future

As we mark our 75th anniversary, we celebrate our past and work to build an even stronger Dannenbaum Engineering rooted in a culture of trust, respect, and excellence.
