Who We are

Willis Engineers, founded in 1962 in Charlotte, North Carolina, is a small consulting engineering firm specializing in water and wastewater systems for local governments and public utilities.  We provide a full range of design, construction administration and operations assistance services to ensure lasting performance and efficient operation.

Our Difference Is Our Strength

At Willis Engineers we successfully complete large, complex projects because we are organized, efficient, and have a level of experience unsurpassed in our industry.  By intentionally limiting our scope of services to public utilities, we provide the highest quality of work for each client.

Staying True To Our Profession

Unlike other engineering firms, the hallmark of the principles of Willis Engineers has remained a client-centered consulting firm that believes engineering is not a commodity to sell but a service to provide our clients.  Successful projects require not only designing facilities with lasting quality but also advocating on behalf of clients during each part of the process.


The staff at Willis Engineers provides comprehensive water and wastewater engineering services to municipalities and public utilities throughout the Carolinas. The size of our firm benefits our clients as each of our engineers manages the project from design through construction ensuring a higher quality project at completion.
