Proof · Taylor, TX

Business park reuse after a county septic denial in Taylor, TX

The county denied the septic permit. We moved the wastewater to a state 210E reuse authorization with zero discharge, approved in 4 weeks.

What clients say

  • Exceptional service from start to finish. Their team understood our development timeline and worked around it. The wastewater plant design was exactly what we need and was approved on time.

    Neil Engineering · Google review

  • Modern Engineering Solutions was great to work with as we had to replace the entire water system within the MH community we own. Mike and his team performed all the engineering work necessary to get the job done. Well done!

    Michael Wallis · Google review

  • We had a great experience working with Modern Engineering Solutions on the single-family homes subdivision project. Mike and his team were very professional, cohesive, and worked well together. We were able to complete the project on time and within budget. I would definitely recommend them to anyone looking for sub division designs!

Case study · Martindale, Caldwell County, TX

4 weeks, where nearby discharge permits took 30+ months

A 210E reuse authorization instead of a contested discharge permit.

We engaged with MES to obtain a permit for our [Martindale] Waste Water Treatment Plant. Mike and his team were successful in securing the permit much quicker than we anticipated.
