City officials in Tucson are promoting a program that teaches residents how to install water-saving systems in their homes in exchange for rebates from the city.

Residents can get rebates for installing conservation-focused appliances, like high-efficiency toilets and washing machines, and setting up systems for greywater or rainwater harvesting. 

The program also offers small grants to get the systems installed for low-income residents. But as of this month, those wanting to get rebates must take part in a workshop before installing their systems. 

City officials say the change will help improve the program by giving residents a better understanding of the water saving systems before they’re installed. Workshops are free and offered several times per month.

Earlier this year, Tucson was one of a handful of  Arizona cities that agreed to take less water from the Colorado River amid ongoing drought.
