PHOENIX — The city of Phoenix released a handbook to promote water conservation through rainwater collection and other methods.

The Green Stormwater Infrastructure (GSI) Handbook aims to help Phoenix residents save water, support local wildlife and decrease temperatures.

The free 25-page handbook, which is available online in English or Spanish, offers step-by-step GSI tips and guidance.

Included in the guide is information on native plants, soil considerations, irrigation recommendations and guidance in securing permits. Depending on the size and scale of the project, you may need to acquire permits or approvals.

“Everything in this information-packed and highly visual new handbook gives our residents and city an opportunity to benefit from GSI integration, all while embracing the beauty of our Sonoran Desert and honoring the wonder of this region,” Tricia Balluff of the city’s Office of Environmental Programs said in a press release Tuesday.

How GSI methods can help with water conservation

GSI methods include the use of rain barrels, permeable surfaces like gravel, soil or pavers. These methods can help reduce small-scale flooding, improve surrounding air and water quality while creating cooler and greener spaces.

“The Green Stormwater Infrastructure Handbook gives our community simple ways to adopt water-saving solutions,” said Heather Finden of Phoenix’s Planning and Development Department said in the release. “Small changes at home can add up, making a big difference in how we manage stormwater and increase shade in our neighborhoods.”

The city of Phoenix encourages residents to explore the handbook and consider adopting GSI practices to contribute to a greener, more resilient city.
