Project Spotlight: Causeway/Central Sewer Upgrades - Mandeville

For years, the Causeway/Central intersection in Mandeville was known for one thing: the smell.

The issue came from the former sewer pump station at that location, which received flow from multiple upstream force mains across the city.

Principal Engineering worked with the City of Mandeville to eliminate the pump station entirely and replace it with a manifold system. We developed a detailed pressure-pipe model to determine how to upgrade several upstream pump stations so that flow could bypass the old site and go directly to the Mandeville Wastewater Treatment Plant.

With the aged sewer no longer collecting at this intersection, the long-standing odor problem was resolved.

We appreciate the City of Mandeville for trusting us with this important improvement for their residents and visitors.

It’s the week of Thanksgiving, which means two things in Louisiana: the weather can’t make up its mind, and everyone’s trying to wrap up projects before the turkey hits the table.

Our team is still out in the field and behind the drawings today, keeping work moving for the communities we serve. Grateful for the people we work with and the work we get to do.

Field Notes: Bucktown Marsh Overlook

Engineering isn’t always concrete and culverts. Sometimes it’s building a place where people can breathe again.

Bucktown Marsh Overlook blends structural work with coastal restoration - turning a shoreline into a space for families, fishermen, and sunset-chasers.

Engineering can be beautiful.
