Septic Permitting

Onsite Waste Water Treatment Systems (Better Known As Septic Systems) Permitting Page

Permits for a new septic system or to renovate the soil treatment part of an existing septic system are required from Health & Sanitation Services.

Septic Permitting Application

This Permit application is filled out online and filed with Health & Sanitation Services accompanied by the proper fee. The fee schedule for Septic Permits is normally $200 if a percolation test is required, or $125 if no percolation test is required. (NOTE: fee change as of 7/1/12)

Percolation (Perc) Test

The next step in the permit process is to prepare for a percolation (perc) test (if required). The Perc Test Instructions gives you the information needed to prepare the site properly for an accurate test result. Once the site is prepared, you can schedule an appointment with the Sanitarian to conduct the test.

The results of the perc test will give Sanitarian the necessary information to issue a permit for your new system.
