Sanitarians issue permits and supervise the installation of sewage disposal systems on new lots or existing properties. They review applications for the installation of subsurface sewage disposal systems and wells, conduct plan reviews, and respond to requests for assistance and complaints. Sanitarians also provide soil evaluations and percolation tests. They review plans for new or improved buildings and site development to assure conformance with health and environmental regulations.
Proper sewage treatment and disposal is essential to public health. Appropriate design, construction, and service of a subsurface sewage disposal system can provide long-term domestic sewage treatment.
