Individuals may obtain a Permit to Install or a Permit to Alter a sewage treatment system to serve a one, two or three family dwelling (STS) or a small flow on-site sewage treatment system (SFOSTS) from the EH Unit after the approval of the submitted design plan.

Once approved, a permit application is required. A registered septic installer and homeowner must be named on permit and permit fee paid to issue permits. 

A homeowner may apply for and install a septic system if the parcel is their primary residence and they take a test regarding the Sewage code with an 80% passing grade.

Once the newly installed septic system is approved for use with submitted as-built information & the system passes a 12-month inspection an operating permit will be issued.
