Rainwater Harvesting Rebate

IMPORTANT UPDATE: As of July 1, 2023, the following rebate program changes will take effect: 

• Administrative changes: 
  • Customers will be required to take an eligible workshop before installation of their system begins.  
  • Customers will apply online for the rainwater harvesting rebate.  
  • Pre-approval will be required before installation of a rainwater harvesting system. Pre-approval entails (1) taking the required workshop, (2) submitting a site plan with system features and (3) their estimated sizes. Upon approval by Tucson Water to proceed with installation, the customer will have one year to complete installation of their system. If customer does not install within one year they will have to retake the workshop and reapply.  
  • Inspection will be required after installation, before rebate is approved. 
• Rebate pricing changes: 
  • Remove the $500 cap for passive systems (basins & earthworks); All water harvesting features on a property can be combined and calculated to a maximum of $2000 rebate. 
  • Calculate the rebate for passive systems based on the size of the basin(s); The rebate for passive systems will be $1.50/gallon, based on basin volume, if the system is correctly sized.  
  • A rainwater harvesting system must be sized to capture at least one inch of rainwater from the drainage area (usually roof area) to receive the full rebate amount ($1/gal active and $1.50/gal passive). If a system is not sized large enough to capture the full one inch of rainfall, the customer will receive $0.50/gal for all system features. A property can have multiple drainage areas.
