DE provides full-service Water Resources engineering services


We approach each Water Resources project with a common set of goals: to deliver exceptional products, meet and exceed client expectations, and ultimately, to make a lasting impact on the community in which we serve. We offer complete cradle-to-grave services to help our clients fund, develop, and execute projects that reduce flooding, preserve the coast, and provide clean water to the community.


Why are we different?

It's simple: we go the extra mile. DE has been instrumental in obtaining funding assistance for water resources needs and advancing conceptual projects forward to design and construction. We have been a leader in helping clients obtain funding from outside sources such as LDEQ, MDEQ, CDBG, LGAP, EPA, etc. as well as providing grant and loan administration.

We have improved countless communities along the Gulf Coast through our Water Resources projects, offering clients solutions that include planning, modeling, engineering design, construction administration, resident inspection, and program management.
