The Rebate Process

The RainWise Program provides rebates that cover most or all of the cost of installing cisterns and/or rain gardens on your property. To receive a rebate, you must be in an eligible combined sewer overflow (CSO) basin and work with a RainWise-trained contractor.

RainWise rebates have recently increased. Visit our Rebate Increase page for side-by-side examples showing the difference in rebate amounts before and after the increase.

Steps to Receive Your Rebate

Visit our eligibility page to confirm that your property is eligible for a RainWise rebate. You may be eligible for a cistern rebate, a rain garden rebate or both.

2. Find a Contractor 

We have RainWise-trained contractors who are ready to work in your neighborhood. Explore our Find a Contractor page and different contractors’ web pages to learn more about them. The first step in hiring a contractor is to schedule a consultation or site visit. Consider attending a RainWise event to meet contractors online or in-person.

3. Work with your Contractor on a Design 

You can work with a contractor to design a RainWise installation that fits your site and your preferences by choosing from a selection of cisterns and plant options.

4. Pre-inspection and Build 

The contractor will arrange for a free pre-construction inspection with the city or county in order to get the green light for the project to move forward. After this is completed, they can begin construction on the installation.

5. Final Inspection 

Your contractor will make arrangements for a final inspection by a city or county RainWise inspector upon completion. This ensures the project will work before the rebate is paid out.

6. Receive your Rebate! 

Work with your contractor to submit a completed RainWise package. After this is completed, you will receive your RainWise rebate in 4 – 8 weeks.

7. Maintenance 

It is important to maintain your rain garden or cistern. Make sure your contractor shows you how or that you contract with them to do regular maintenance. For more information and resources, visit our maintenance page.
