Do I need a permit?
- Check the Do I need a permit? page to learn about permitting requirements for water-related projects.
Water-related program contact information
- Projects that impact Minnesota's water resources are regulated by a variety of state, local, and federal agencies. In many cases, a permit is required from one or more of these agencies before proceeding with the project. Check the county-by-county listing to find the agency contacts in your area.
Well Construction Preliminary Assessment
Preliminary approval is required before drilling a well that will be used to withdraw more than 10,000 gallons of water per day or 1 million gallons per year. To apply for a Well Construction Assessment, please use the MNDNR Permitting and Reporting System. If you are using MPARS for the first time, you will need to create an account. Once created, click on the link in the Actions box called "New Well Construction Assessment”.
MPARS is the easiest and most convenient method for most people to request a well assessment, and allows for faster response times. If it is not possible for you to apply online, a paper form may be downloaded by clicking the link below.

If you are already certain that your project will require a permit see the application form.
