The Permits and Engineering Section is responsible for reviewing and approving engineering documents submitted by public water systems. Staff ensure engineering documents meet the Safe Drinking Water Regulations and Design Standards. The Section also ensures water systems have technical, managerial, and financial capacity before issuing a Permit to Dispense. Implementation of the Backflow Prevention Program protects source water and prevent cross connections. Staff utilize the Area Wide Optimization Program to provide technical assistance.

Owner Supervised Program
An Owner Supervised Program (OSP) allows a public water system to obtain approval to construct several waterline extensions or replacements without submittal of a construction permit application. Approval is granted for a period of up to five years. Required information to obtain an OSP is located in Chapter 1.8 of the Minimum Design Standards for Missouri Community Water Systems.
