Household Sewage Treatment Systems

The Defiance County General Health District Household Sewage Treatment System (HSTS) Program involves permitting and inspection of sewage treatment systems.  HSTS are found in areas where there is no access to sanitary sewer service.  A Household Sewage System Treatment System Installation Permit must be obtained prior to constructing a new system or significantly altering or replacing an existing system.

The Ohio Department of Health (ODH) established a Sewage Treatment Systems Rule Advisory Committee to provide comments and help develop a consensus on proposed rules for Chapter 3701-29 of the Ohio Administrative Code.  The office of the Secretary of State of Ohio has reviewed the final draft of Chapter 3701-29 of the Ohio Administrative Code and has stated that the effective date will be January 1, 2015.

The Defiance County General Health District is also responsible for licensing installers and septic haulers.  All work on an HSTS must be completed by a licensed installer or service provider.  For more information on how to begin the installation process, please contact the Health District at 419-784-3818.
