Platte County Health Department
Sewage Program
The Environmental Health staff evaluates proposed subdivisions to determine if onsite wastewater treatment systems are feasible. This cooperative effort between the Platte County Health Department and the Platte County Planning and Zoning Department eliminates many potential health problems associated with the improper disposal of human waste.

Before an onsite wastewater treatment system is installed in unincorporated Platte County, the homeowner is responsible for obtaining a permit from the Health Department. The Environmental Health staff issues permits and permit exemptions, inspects new, repaired, and existing systems, and investigates sewage complaints. Follow the instructions below to apply for a permit or permit exemption, to request an inspection, or to lodge a complaint.
