Wastewater Construction Permitting
Wastewater Construction Permitting
The Missouri Department of Natural Resources reviews wastewater construction permit applications to ensure plans and specifications for wastewater sewer systems and treatment facilities are complete with regard to the minimum requirements and the proposed construction is acceptable with regard to accepted design standards for wastewater systems to protect the public health and the environment.

Selecting an Engineering Consultant
All engineering reports, plans and specifications must be signed, sealed, and dated by a Missouri professional engineer. The procurement of planning and design services is one of the most important steps in the design or upgrade of wastewater systems. Ten tips to help communities hire an engineer
Qualifications-based selection (QBS) is a recommended process to negotiate procurement of an engineering firm based on qualifications and competence relative to the work to be performed. Below is a link to the QBS proper procurement steps and information provided by the American Council of Engineering Companies (ACEC) Missouri.

All construction permits for new or expanded discharges are required to follow the Missouri Antidegradation Rule and Implementation Procedure.
The department encourages the development of innovative wastewater treatment processes or equipment. Many communities are facing more stringent effluent limitations and are looking for practical and affordable solutions. You can view the ongoing and completed pilot project information.
The department offers a review and approval process for municipalities with standard sewer specifications and details. Municipalities who receive department approval will not be required to submit a copy of their specifications and details with a sewer extension construction permit application. You may view approved and currently under review municipalities.
Do you have questions regarding the construction permitting process or new rules and regulations? Take this opportunity to learn more at the engineering workshops sponsored by the department. Previous workshop presentations are available below.
The department is currently working on rulemaking changes to 10 CSR 20-8. These changes will align the state's rules with the most current version of the Recommended Standards for Wastewater Facilities (otherwise known as the 10 States Standards).
