Sewage system installation season is April 15 – November 15. Weather permitting, installations MAY continue after consulting with us prior to any work being done. We must issue a permit before work can begin. Contractors who install sewage treatment systems and who “clean” sewage tanks must be registered with us to perform the work.

Completed installations are inspected for compliance before we approve the system. Proper installation prevents contamination of groundwater supplies and reduces the incidence of sewage-related nuisances. Our Environmental Health Division responds to written public health nuisance complaints regarding systems that are discharging odorous, grey, or black wastewater.

Residents of Ashland County who have a failing Household Sewage Treatment System (HSTS) may be eligible for a HSTS Replacement and Repair Loan Program. Rental properties and new build homes are not eligible for assistance. More information about failing household sewage treatment systems and the loan program can be found here.
