Onsite Sewage

Ste. Genevieve County is contracted with the Missouri Department of Health & Senior Services to regulate Onsite Sewage system construction, repair, and violation investigations. Any construction, modification, or repair on residential properties less than three (3) acres, generating 3000 gallons or less of wastewater or if more than one residence is on the property shall require plan review, site investigations, and a construction permit issued by this office prior to any earth moving.

All commercial facilities needing onsite sewage systems are required to be permitted through this office. Some exemptions apply in certain situations. Contact us for assistance. Further detailed information about the Missouri Laws accompanied by Department of Health & Senior Services Rules governing onsite sewage systems can be found here (Link opens in a new window, Adobe Viewer required).

Sewage Complaints/Investigations

On-site Sewage complaints are investigated within a few weeks upon receipt and the EPHS determines upon investigation if the complaint warrants a Violation Notice to be issued. The complainant MUST be an adjacent or adjoining property owner or an aggrieved party.

Systems that are surfacing, leaving the property, contaminating above or below ground water, produce odor, mosquito breeding, etc. are examples of systems found to be in violation. The EPHS determines whether a Violation Notice shall be issued for complaints.
