The Clark County Combined Health District conducts site approvals at the request of local zoning officials to determine whether proposed construction projects may impact on-site sewage systems and private water systems.
Our regulations require a ten-foot isolation distance from construction projects to both private water systems and on-site sewage systems. This ensures that these systems remain accessible for maintenance and repairs and that they are not disturbed by construction activities.
Please be aware that all properties with on-site sewage systems must maintain sufficient area for replacement of the sewage system. A construction project may be disapproved if it interferes with the available area for replacement of the sewage system.
If you need a site approval, please fill out the application (get the form here) and attach a sketch of your proposed construction. The sketch need not be to scale but must give sufficient detail and/or measurements that the exact location can be determined in the field by an inspector. Example sketches.
Applications may be submitted in person at the Clark County Combined Health District, e-mailed, or faxed to 937-390-5625.
