Who handles septic permits in Sussex County

Delaware licenses onsite wastewater work by class, and publishes the whole licensee list as open data. Each class is a separate credential — a company licensed to haul liquid waste is not thereby licensed to install a system.

Licensed companies in neighbouring counties

A Delaware septic licence is valid statewide, so a company listed in an adjoining county can legally do the work in Sussex County.
