|Civil engineering is the design of physical improvements in the environment, the treatment of drinking water, wastewater and the design of drainage facilities. There are several sub-disciplines of civil engineering; general civil site, structural, sanitary, environmental, traffic, soils, and coastal engineering.
Holmes and McGrath, Inc. has expertise in several of these areas. Our main field is general civil site engineering and environmental engineering. Through many different projects and research we have developed expert knowledge in the design of drainage system collection and treatment, wastewater treatment in filters and soils, as well as the movement of nitrogen in the environment.
