Designers by Area Code 

Design Forms

Per the suggestion of several local health districts, the Ohio Department of Health Sewage Program has drafted example inspection forms in Excel format for the inspection of sewage treatment systems (STS). One set of forms is for the complete inspection of newly constructed or repaired systems, and the second is for the annual inspection of previously installed and approved systems as required per  Ohio Administrative Code 3701-29-09 (H). These forms may be taken and customized by the local health districts.

Example STS Inspection Forms
