Utility Engineering

While roads and streets have great visual impact, the underlying utility systems are critical.  Providing safe drinking water and removing sanitary waste is necessary for a high quality of life. Here are some of the services we provide:



Securing an adequate, safe water supply, and treating, storing, and delivering it is challenging. HLA has years of experience coordinating with the Washington State Department of Health and water purveyors to develop projects. From initial planning stages through financing, design, and construction phases, our staff has the knowledge and experience to ensure water projects succeed.



Design of sanitary and industrial wastewater collection and treatment facilities requires technical expertise as well as experience with state and federal regulatory and funding agencies. This, in addition to a working knowledge of wastewater treatment facility operation and our long-standing relationship with the Washington State Department of Ecology, results in cost-effective projects that reduce adverse impacts to the environment.



From headworks rehabilitation to pipeline replacements, we have many years of experience in all aspects of irrigation design, delivery and allocation. We are able to provide the plans and designs to handle any construction method necessary for irrigation water distribution.
