Maintenance
On-going maintenance is essential to keep your RainWise installation working properly.
Seattle Public Utilities and King County are counting on your RainWise project to prevent polluted stormwater from going into our waterways. Your cistern and/or rain garden is made possible with public funds. In return, RainWise requires homeowners to maintain their RainWise project for five years.
Understand Your RainWise Commitment
Read the RainWise Homeowner Agreement, which customers sign before receiving a rebate.
Inform the next homeowner about RainWise. If you are selling your home which has a RainWise installation, please email us at rainwise@seattle.gov. Your RainWise project must be listed in your Seller’s Disclosure Form to let the next owner know about your cistern and/or rain garden.
