Our People

Our Work

Beyond the scope

As the population grows daily, so does the need for reliable water solutions. Our clients have the programs, projects, and vision to meet these needs. MKN has the experience, innovation, passion, and specialized team to make them a reality.

More than just engineers, we see ourselves as client advocates, carrying projects from concept to delivery and handling the details for everything in between.

Hard work pays off...

MKN was a great help with our wastewater treatment plant and pipeline project. They consistently foresaw and resolved issues before they became problems. We will be using them again for future projects.
