Engineering Overview


The Engineering Division, as well as the entire Stover business organization, originated from Dr. Enos L. Stover’s initial one-man wastewater process engineering and consulting business established in 1984. From its inception, the company operations grew to include an in-house detail design team, providing a full Drinking water in the test tube for chemical and microbiologicalrange of services including wastewater treatment plant design/build and construction management services.

THE STOVER GROUP operates from the corporate office, laboratory, and warehouse facilities located in the City of Stillwater, Oklahoma. An engineering design branch office exists in Meridian, Idaho. The organization currently has a staff of over 70 employees, which includes professional engineers, licensed operators, environmental scientists, and other technical experts.

THE STOVER GROUP is continually evolving to meet the needs of its clients. This is done by anticipating trends in the regulatory climate, accurately assessing the needs and priorities of its clients, and developing new technology and problem solving techniques to better meet those needs. Along with the growing complexity of environmental regulations, the trend toward corporate downsizing has required many clients to seek technical supporting from outside consulting firms. THE STOVER GROUP’s broad in-house capabilities, together with its team-building approach to problem solving, has produced a long track record of successful and economical solutions for its clients.

THE STOVER GROUP’s dedication and c0mmitment to its clients begins with the expertise of its interdisciplinary team of engineers, scientists, regulatory specialists, and professional support staff. Through integrated, advanced technology problem solving techniques, team-building with its clients and consultants, and professional experience, THE STOVER GROUP continues to provide the highest level of service to its clients.


The Engineering Division currently occupies extensive office and library space, which includes a filamentous bacteria identification laboratory (shared with the Operations Division) and an extensive treatability study laboratory.
