We believe in helping Indiana communities and industries solve their toughest environmental infrastructure problems, and achieve their near and long-term goals!

As a representative of your community or industry, what are your primary concerns?  Perhaps it’s the constant worry of your aging infrastructure that is no longer meeting your needs, or maybe it’s the never-ending regulatory requirements that are straining your budgets to the breaking point.  Perhaps you are needing experienced guidance finding the eligible grant dollars or financing to support your growth plans.

In many cases, these challenges may seem insurmountable… but not to us at Commonwealth Engineers.  Helping communities and industries find solutions to their toughest environmental problems is what we’ve been doing since 1974. Our core team of engineers, scientists, regulators, and designers are specialized to solve your most pressing matters related to wastewater, potable water, storm water, sustainable infrastructure, dams, levees, waterways, site civil, and energy-saving systems.

We believe that our team of professionals is second-to-none. Our diverse team of professionals has been hand-picked from some of the best universities in the state of Indiana. In addition, since so many of the problems you are facing stem from mandates through the Indiana Department of Environmental Management (IDEM), we have former IDEM employees on staff to help you easily navigate through the forest of current and future regulations.

Our focus for over 40 years has been and will continue to be, a commitment to serving Indiana communities and industries.  Like you, we live, work, and play in the heartland of Indiana.  Like you, we want our families to live in a sustainable, healthy environment with a state-of-the-art infrastructure that supports job growth, not only for our generation but also for future generations.

To our existing partnering communities, we thank you for the trust you place in Commonwealth Engineers.  To new communities, we invite you to explore how we can use our wealth of resources to master a common goal.  To job seekers searching for a meaningful career where your abilities will be truly appreciated and acknowledged, we encourage you to consider a professional career in our Indianapolis Headquarters or Regional Offices in Fort Wayne and Evansville.
