What Stover Group does
The Stover Group is a privately-held environmental engineering firm founded in 1984 by Dr. Enos L. Stover in Stillwater, Oklahoma, that provides water and wastewater treatability, engineering, and contract operations services to industrial, municipal, and government clients across the United States. The firm operates through three integrated divisions: Operations (contract operation and management of industrial wastewater treatment plants at client facilities), Engineering (concept engineering, treatability and process development, and industrial wastewater engineering), and Technologies (proprietary treatment processes and software).
The company's technology base centers on proprietary biological and physical-chemical treatment methods. Dr. Stover developed and holds two granted U.S. patents: the Biochemically Enhanced Hybrid Anaerobic Reactor (U.S. Patent No. 5,228,995, 1993), which combines suspended-growth and fixed-film treatment for high-strength industrial wastewater, and the Biochemically Enhanced Thermophilic Treatment (BETT) Process (U.S. Patent No. 6,036,862, 2000), developed over seven years for stabilization and mass reduction of waste sludge and treatment of high-strength industrial wastewater. The firm also developed FIL-IDENTPro, a filamentous bacteria identification software application with patents pending. Operations are supported by an extensive bench/pilot/full-scale treatability study laboratory and a filamentous bacteria identification laboratory at the Stillwater headquarters, with an additional engineering design branch in Meridian, Idaho.
The business model is B2B professional services plus managed services, with contract-based pricing tailored to project scope. Revenue is generated through engineering design and consulting engagements (feasibility and planning studies, conceptual and detailed design, construction engineering, start-up, and operator training) and recurring contract operations contracts where Stover supplies specialized personnel in lieu of clients hiring in-house treatment plant staff. End-markets include pharmaceutical, food and alcoholic beverage processing, refinery and petrochemical, municipal wastewater utilities, government entities, and third-party environmental consultants. The firm is founder-owned and controlled by Dr. Enos L. Stover, with no disclosed external institutional investment, and operates as Stover & Associates, Inc.
