Overview

An onsite sewage treatment and disposal system, also known as a septic system, treats and properly disposes of sewage including gray water. All plumbing fixtures such as toilets, sinks, bathtubs, showers, washing machines, dishwashers, or anything else that generates human wastewater must be connected to an approved sewage system.

Site Evaluations - First step in obtaining a construction permit for new development,

On-Site Septic Permit Application - A Permit must be obtained prior to conducting the installation, repair, or alteration of your septic system and after a site evaluation has determined your site to be suitable for on-site wastewater disposal (repairs and alterations may need a soil analysis with test pits for existing locations that have never been evaluated for suitability. Please contact us if you are unsure about the suitability of your site.)

Please fill out the On-site Septic Permit Application completely, along with a detailed plot plan, and sign the Authorized Representative at the bottom (if you are representing the applicant i.e. installer, friend, neighbor etc… please fill out the Authorized Representative Form)

A DEQ Land Use Compatibility Statement (LUCS) will also need to be included with your application which should be signed by your local county planning office prior to submitting the application.
