Onsite Wastewater Services

LeRoy Surveyors & Engineers, Inc. (LS&E) provides wastewater services—including residential and commercial design—to municipalities, developers, school districts, retail centers, consultants and contractors in the Pacific Northwest.

As a large, full-service civil engineering and development services firm, we’re capable of handling a full range of wastewater projects. Our staff has expertise from small residential septic to large commercial systems.

LS&E is the first choice for difficult or specialized jobs that present unique wastewater conditions.
