Engineers and installers under one roof

Most septic companies send the design work to an outside engineer, and most engineering firms never pick up a shovel. We do both. The same company surveys the site, designs the system, handles the permit, installs it and comes back for the inspections.

That matters when something doesn't fit the standard answer: a tight lot, a high water table, a commercial building with more flow than a house, or a permit that has stalled. You talk to people who can do the math and do the work.

  • 50+ years of engineering experience
  • Licensed installers and technicians (TCEQ)
  • A written estimate before any repair or upgrade

What customers say

Reviews from Yelp, HomeAdvisor and Google, quoted as written.

Stewart Engineering did a fantastic job for me on a large, complex construction & development project. They assisted with the design, engineering, and consulting services. Their results far exceeded my expectations. And they were really good to work with. In particular, Joe was extraordinarily phenomenal! I will definitely be calling Joe at Stewart Engineering Services on my next project.

Mr. Stewart has just blessed our family with his services. I highly recommend Mr Stewart. It's been a struggle figuring out the whole permit process, We are finally sealed and ready for continuing and completing our plans for our home. Thank you Mr Stewart we will pass on the blessing.
