On-site Sewage Treatment Systems (OSTS)

The Environmental Health Division requires permits for all new on-site sewage treatment systems and/or repairs to existing on-site sewage treatment systems which includes: septic tanks, drain fields, seepage pits, cesspools or holding tanks. All work must be permitted and performed by a licensed installer or the homeowner. Inspections of existing systems are provided upon request. Proper treatment of sewage is necessary to prevent waterborne illness and ground/surface water contamination.
