Customized Projects

Rebate Amount Potential Water Savings
$0.05/gallon saved or 50% of the project cost dependent on project

Rebate values are based on future water capacity costs and estimated water supply from these future water sources. Qualifying devices are selected based on demonstrated perpetual water savings over the lifetime of the device. 

How It Works

Choose from a pre-approved list of devices (the menu options) with predictable savings and defined monetary incentives. We'll either give you the rebate value listed above or 50% of the actual product costs, whichever is less. 

Looking for something a little different (think car wash upgrades, laundry facility improvements, etc)? We'll work with you on a custom technology that will meet your business needs and demonstrate water savings with a pay-for-performance model.

  • Customized Project Rebates: For items not listed on the pre-approved menu above, Water Conservation Staff will review applications on a case-by-case basis. All projects will be capped at 50% of real product costs, excluding labor, tax, shipping, and other costs, OR a rebate rate of $0.05/gallon of water saved, whichever is less. 
  • Half the amount of rebate money will be paid after these 4 criteria are met:
    • Inspection of the devices to be retrofitted
    • Discussion about anticipated water savings with the business
    • Receipt of the Application Form and W-9 Form
    • Receipt of the invoice or proof of payment
  • The remaining half of the payment will be made after a 6-month performance review and demonstrated water savings
  • Projects must be sustained for at least 5 years or transfer of property title, whichever comes first. If the equipment requires replacement prior to 5 years, it must be replaced with equipment of equal or greater water efficiency.
