The Interim Statewide Sewage Rules (Ohio Administrative Code Chapter 3701-29) and local health district regulations allow for the use of traditonal leaching trenches on sites determined to be suitable for subsurface soil absorption systems.  Gravelless and chamber leaching trench products are approved for use.  The Ohio Department of Health (ODH) has the authority to approve the use of other systems and components in accordance with law and rules.  The Technical Advisory Committee makes recommendations to ODH regarding the approval or disapproval of systems and components that differ in design or function from those established in the Interim Statewide Sewage Rules.
