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 through July, 2000, the division 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.

In early 2000, it was determined by company management that the company’s efforts to provide, in-house, the full range of wastewater treatment services for its clients had in fact detracted from the company’s core area of business, namely process design engineering, process consulting and operations services. It was determined that full-range services could be better and more economically provided through teaming arrangements with other established and well staffed engineering companies which can provide, and whose core area of business is, the detail design and construction engineering services, leaving The Stover Group to concentrate on what it does best.

As a result of this management decision, the division’s detail design and construction engineering group was closed, and all detail design and construction engineering is presently being provided by teaming with other companies.



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.
