Skelly and Loy provides professional engineering and environmental services to various industries and businesses, and governments.

Skelly and Loy offers full-service construction services related to wastewater and water treatment systems, stream restoration, stormwater Best Management Practices, and other environmental infrastructure systems to a wide range of municipal, private, industrial, and non-profit organizations and clients. Construction experience includes new system installation and startups, existing system upgrades, system retrofits, and system decommissioning or closures. Services are performed to be in full compliance with regulatory permitting and building codes and include completion of final regulatory permit reporting and as-built documentation as needed.

Skelly and Loy's professional affiliations are among our most valuable business resources, as well as one of our greatest benefits to our clients. Our participation in organizations strengthens relationships with our clients, builds a better understanding of their needs, and allows us to work side-by-side to support legislation, social causes, and career development. Current trends, innovations, and expectations for the future are discussed through formal training, seminars, and workshops. More importantly, the informal knowledge and experience sharing that come through time spent networking with our clients and colleagues are invaluable.

Skelly and Loy's Environmental Services are provided by a professional staff that includes environmental engineers, ecologists, biologists, hydrogeologists, botanists, and other environmental scientists. Our staff has extensive experience in environmental planning, design, construction, and documentation. The depth and breadth of our staff experience include detailed field surveys, technical writing, effective interagency coordination, and pro-active public involvement. As a result of the staff's wide variety of project experience, they have developed and nurtured professional relationships with many federal and state resource and regulatory agencies.
