TN&A provides professional services on a wide variety of municipal projects. Our experience includes planning, evaluation, design, and construction. We have completed wastewater collection and treatment designs, sludge management projects, water distribution and treatment designs, site and roadway designs, storm water drainage and wetland designs, and natural resource studies.

Our multi-disciplinary staff of professionals, including engineers, hydrogeologists, biologists, surveyors, and technicians offer experience in municipal engineering as well as remediation, and health and safety issues. TN&A has a core of experienced project managers who provide the leadership to deliver your project on schedule and within budget.

For the City of Milwaukee’s River Walk, TN&A performed the survey and design of the grading, paving, and storm water collection of various streets, parks, and parking lots. One aspect of this design project included treatment of storm water from an interstate bridge. Regulatory agencies used this design to evaluate manufactured storm water treatment devices for treatment efficiency.


For a USDA Forest Service campground, TN&A recently designed both a new water distribution system and an innovative wastewater collection system using grinder pumps and small diameter force mains. Another project involved the design of improvements to the Milwaukee collection system that included both open-cut and tunneled sewers as well as new flow control devices.
