Sewage Treatment Systems Permits & Inspection

The Zanesville-Muskingum County Health Department works to protect the environment and to ensure a safe drinking water supply by preventing contamination. This effort involves the inspection of sewage treatment systems at homes and investigation into other forms of water contamination.  

This program reviews potential new parcels to ensure enough area is available to install a sewage treatment system, reviews designs for new sewage treatment systems, inspects installation of sewage treatment systems, investigates nuisance conditions, and provides operational permits for the continued use of sewage treatment systems. 


Sewage Treatment System Records 

We may have records of your sewage treatment system depending on the age of your house. To request a record, please email or call 740-454-9741 extension 282 with the following information:  

  1. Address 
  2. Date of construction of house OR installation of system
  3.  Installer of system OR builder of the house   


Purchasing or Building on a Lot? 

Have the site evaluated early in the process because not all lots provide enough usable space for sewage disposal. Sewage evaluation cannot occur without a site and soil evaluation done by a soil scientist. We will help review the evaluation and determine if sewage disposal is feasible on the lot.  

If you are considering the placement of a manufactured home on your property, additional rules will apply. Call the Ohio Manufactured Homes Commission for more information at (617) 743-6010 or email You may access their website here: Manufactured Homes Program (MHP) | Ohio Department of Commerce
