Our Success Is

Our Service

21 Design provides construction support, surveying and mapping, civil site design, potable water, and wastewater treatment/collection services for projects in the Midwest region of the United States. Our expertise is unmatched, and your project is important to us.


21 Design surveyors are knowledgeable and experienced. There is no job too great or too small for this department, from quarter-acre boundaries to 300-acre subdivision stakeout, they can do it all.

Civil Engineering

Our civil engineers are the best and the brightest. We cover a large scope of the civil field, including large commercial site design, wastewater treatment design, and wastewater treatment remodels.


Client consultations are quick and simple. With our help, there will not be overwhelming situations. We are here to listen and guide. The email template on our contact page allows for easy scheduling.

The City of Washington and 21 Design Group have work together on water system design projects and other public utility projects in the traditional public utility / consultant role and permitting agency / consultant role.

In each of the projects, 21 Design Group has performed very well and provided high quality consulting / design services.

I would not hesitate to consider 21 Design Group for a future public utility consulting and design project.
