What Allied Engineers does

Allied Engineers, Inc. (AEI) is a privately held civil engineering firm headquartered in San Ramon, California, that specializes in the design and construction of wastewater reclamation systems for small communities, commercial developments, and industrial clients. Operating for more than 25 years, the firm has delivered engineering services across over 60 communities in the United States and internationally, with a cumulative portfolio that has enabled construction of more than 10,000 homes with a value exceeding $2 billion. Allied serves municipalities, counties, private developers, resorts, golf courses, country clubs, wineries, and light-industrial facilities, with a primary geographic concentration in California (55+ projects) and additional work in the broader western United States and select international locations including the Czech Republic.

The firm's core technical offering is wastewater reclamation system design incorporating tertiary treatment processes — including pressure sand filtration, decentralized water recycling plant architectures, storm water capture integration, and solar power integration at treatment facilities. Allied Engineers provides end-to-end services spanning planning, permitting, systems engineering, design engineering, operation and maintenance assistance, and construction management. A separate Design/Build offering provides fixed-price design-and-construction services with single-entity responsibility, which the firm markets as delivering lower cost, shortened schedules, and improved quality. Treatment system features emphasize redundant unit design for reliability, low/high-flow flexibility, computer monitoring and remote alarms, and minimal operator attention — addressing the operational constraints of small communities and remote commercial developments.

Allied Engineers generates revenue through professional engineering services and fixed-price design/build contracts, both project-based and tailored to scope, capacity requirements, and complexity. The firm operates with 11–50 employees and pursues an enterprise field sales motion built on direct relationships with municipal decision-makers, regulatory agencies (including the California State Water Resources Control Board and Regional Water Quality Control Boards), and industry associations such as WateReuse, the Water Environment Federation, AWWA, the International Water Association, and the Design-Build Institute of America. Revenue is not publicly disclosed, and the firm is closely held with no external funding or institutional investors identified; the company is led by President Robert E. Dawyot, P.E. and Vice President Vlastimil Cejna.
