Basic Outdoor (2500 ft² – 210 gpd) – $5,250

Note: The amount of outdoor use is based on the amount of irrigation required for turf grass according to the Washington Irrigation Guide (20.80 inches/yr). A larger amount of landscaping or garden area may be possible with the same number of gpd.

How We Mitigate

A DWE certificate means that your home has a net zero impact on the local water supply of your neighbors, streams, and salmon*

* When certificate requirements are met

DWE replenishes groundwater through the recharge program, designed to return the same amount of water to our streams and rivers as is taken out by new water uses

One type of the mitigation projects DWE operates are aquifer recharge sites. These sites strategically replenish groundwater and local streams that are depleted by new well withdrawals. In times of abundant water, the sites are used to infiltrate and create additional restoration to the watershed.
