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.


Wastewater Engineering Construction Permitting Manual

The Wastewater Engineering Construction Permitting Manual is a tool developed to guide review engineers, consultants, and the general public through the construction permitting process. More information

Construction Permit Status

You can search the department’s Missouri Clean Water Information System for construction permit applications in process.  Applications in Process Search

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.

You can search for a licensed professional engineer in the state of Missouri on the Missouri Division of Professional Registration.  Licensee Search
