Can my Septic System use Off-Lot or Off-Site Discharge?

If you need to install a septic system, or replace a failing system, you may wonder, “Can my septic system discharge wastewater off of my lot?”

What is an off-lot septic system?

This is a method of dispersing the effluent (wastewater) from your septic system off of your property, where it will eventually join a stream or lake.

Because effluent that leaves your property will have an impact on the surrounding environment, it is regulated by your local Health Department and the Environmental Protection Agency (EPA). 

Off Lot or Off Site Discharge for Septic

Off-lot discharge is possible, but only for certain homeowners under certain conditions: 

Off-site discharge in an existing home or a new home build

If you are replacing a system in an existing home, you will need to have a design submitted and approved for off-lot discharge, even if your home currently drains off of your property.  Rules began to become stricter starting in 2007 and now require an affidavit from your local health department declaring that there is no other option.   

If you are building a new home in Ohio and need to install septic, be aware that off-lot permits only apply to properties established (or grandfathered in) before 2007. Any new residential property most likely will not be permitted to discharge wastewater off-lot. Some empty lots have been platted and grandfathered in; check with the county to see if your land qualifies.

How to get an off-site discharge permit in Ohio

Whether you are replacing a septic system in your existing home or building a new home, you will need to start by having a soil analysis completed by a licensed professional in order to have any design completed and approved.

Then, the Health Department will look at a few key considerations in order to grant an off-lot permit, including:

Shallow soil depths are common in Ohio; however, that reason alone may not be a strong enough argument for an off-lot discharging system.  If you cannot get an off-lot permit due to shallow soil, you may be given a couple of options:
