Exempt Well Mitigation Credits allow rural homeowners, businesses, and developers to meet new regulatory requirements for outdoor exempt well water use.

Permit-exempt wells are a common way for rural residential and small commercial water users to legally obtain water in Washington. In water-scarce basins, there are concerns that increased exempt well usage may result in injury to the watershed system. The Walla Walla is one such basin.

The Washington Department of Ecology requires mitigation for consumptive water use by new exempt wells if they meet the following conditions:

  1. Drawing from the shallow gravel aquifer, and
  2. Located in an area zoned for land parcels of 10 acres or less.

To help accomplish this mitigation, the Partnership purchases water rights and divides them into Exempt Well Mitigation Credits for sale to prospective water users.
