Don’s Story

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.

Donald R. Voigt, P.E.
Water/Wastewater Equipment Applications Engineer
Certified Energy Manager

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 Energenics 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.

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.


ATLANTA, GEORGIA – The Association of Energy Engineers announces that Don Voigt P.E., C.E.M. has met the educational, experience and rigorous testing requirements needed to qualify as a Certified Energy Manager® (CEM®) and has joined the ranks of over 8,000 CEMs worldwide.

Mr. Voigt is a principal in the engineering firm of Engineered Equipment Integration ( and is a licensed Professional Engineer (WI and FL) with extensive experience in engineered systems – specializing in process machinery for water treatment in public and industrial utilities. He has shared his knowledge in systems engineering through numerous technical presentations both in the U.S. and abroad.

The Association of Energy Engineers, AEE, founded in 1977 and located in Atlanta, Georgia, is a nonprofit professional society of over 11,000 members in 78 countries. Established in 1981, the Certified Energy Manager® (CEM®) provides a recognizable affirmation of demonstrated competencies in a wide range of energy-related principles and practices. Professionals seeking the CEM® designation must meet a board-approved list of pre-qualifications in experience in the field and prior educational achievements.

The CEM® program is widely accepted and respected both in the U.S. and internationally. Its designation is recognized by the U.S. Department of Energy, the Office of Federal Energy Management Programs (FEMP), and the U.S. Agency for International Development, as well as by numerous state energy offices, major utilities, corporations and energy service companies.
