Team Approach to Water & Industrial Systems Engineering

EEI's philosophy is that a system project is best accomplished by a team that includes engineers, owners, operators, equipment suppliers, installers, and consultants. EEI's purpose in this team is to utilize decades of experience in utility design engineering to facilitate cooperation for optimum system design at the best cost.

Put Your Project in Experienced Hands

Since 1979, Don Voigt has been an applications engineer with one of the leading systems engineering and supply partners in the field of water treatment and control systems for municipal and industrial water and wastewater applications.

Don's primary expertise lies in engineering design application for systems applied to water/wastewater treatment in the municipal and industrial marketplace.

Don founded Energenecs in 1979, and the company has since grown to become one of the leading systems engineering and supply partners in the field of water treatment and control systems for municipal and industrial water and wastewater applications, with operations mainly in the Midwest region of the USA.

As owner and president of Energenecs, Don included managed a staff of 20 engineers, field service technicians and related support staff. His position provided him with a unique overview of both success and failure of a wide variety of machinery employed in water and wastewater systems.

Don has divested Energenecs in order to focus a larger portion of his time in the area of machinery design/applications in water and wastewater utilities. He is also a frequent and popular speaker at regional and state water and wastewater meetings. More…

A few examples of projects…

Milwaukee, WI. (Jones Island Facility) - Equipment applications engineer and manager of pilot demonstration for what was, at the time, the world’s largest belt press installation for a municipal plant (24 – 2 meter belt presses).

Whitewater, WI – Lead applications engineer – including pilot plant demonstration - for the first simultaneous water/air backwashed filter in the USA. Worked in tandem with Marquette Univ graduate student and Dr. Jim Young of Iowa State Univ in demonstrating the effectiveness of this concept which has since become the standard practice for water and wastewater granular media filters.

Grand Chute – Menasha West WWTP (Grand Chute, WI) – Lead applications engineer for one of the first operational ATAD facilities installed in the USA (in concert with McMahon Associates of Menasha, Wisconsin)

Rhinelander, WI – lead applications engineer for one of the first “Pista Grit” traps installed in the USA (circa 1972).

Wisconsin Focus on Energy (a user-funded energy reduction management group) – Served as lead in a successful project which was the first USA Benchmarking study that compared energy consumption of 10 Wisconsin wastewater and water plants to world standards for energy consumption – teamed with WRc of Great Britain and McMahon Associates of Menasha, WI. View the full report.

Wausau Papers, Brokaw, WI – Applications engineer involved in one of the first USA installations of “cascade” system for combined belt thickener/belt press applied to thinner sludges (circa 1990) – teamed with Baisch Engineering of Appleton, WI

Marquette, MI and Manitowoc, WI, municipal water plants – installing the first large scale microfiltration plants in USA (Memcor/Siemens) Served as lead applications engineer and local field representative for pilot plant demonstration/evaluation for these pioneering water plants treating “Great Lakes” water supplies.

Publications and Presentations

Mr. Voigt is widely known throughout Wisconsin and the Upper Peninsula of Michigan as a technical presenter on a broad range of water & wastewater topics – from flow meters to energy optimization techniques. He has recently expanded to an international focus, presenting his report, Wastewater Energy Efficiency is Attainable, at IFAT, Munich Germany on May 7, 2008.

He has written multiple publications for trade journals – including “Pumps and Systems Magazine” and WEF Journal.
