RainWise rebates combat pollution! With every storm, rain carries pollutants off our roofs, driveways, and other hard surfaces to local creeks, Lake Washington, and Puget Sound. Rain gardens and cisterns can help control this stormwater, but we need your help! In selected areas of Seattle, the City of Seattle and King County will pay up to 100 percent of the cost of installing rain gardens and cisterns on homeowners’ properties.

This in-person info session is for homeowners in RainWise-eligible basins throughout Seattle who are interested in learning more about the RainWise program and rebates. At this info session, you will learn:

about the stormwater problem,

about the solutions we’re using to solve it, and

how you can help and get a rebate of up to 100% of the cost of cisterns and/or rain gardens.

We’ll cover the rebate process, and how to select a contractor. You’ll have a chance to ask questions to Program staff, hear from a fellow RainWise homeowner, and possibly chat with RainWise contractors about your future project!

About RainWise: RainWise is a partnership program of King County Wastewater Treatment Division (WTD) and Seattle Public Utilities (SPU). RainWise rebates cover up to 100% of the cost of installing rain gardens and cisterns on eligible properties. Rain gardens and cisterns help protect Seattle’s waterways by keeping stormwater out of the sewer system. When too much stormwater enters the sewer, polluted water can overflow into Puget Sound, the Duwamish River, and other lakes and bays. RainWise projects can also add attractive landscaping to your yard and provide a way to collect rainwater.
