Why rely on a water source that costs money, energy and is overallocated? Groundwater is becoming harder to find and extract, and water management and conservation is a rising concern as populations and economies continue to expand around the globe. The process of treating and pumping municipal water also costs money and energy which is reflected in our utilities. Water harvesting reduces this expense by tapping into a free resource.  When you learn to utilize your yard’s natural water supply to capture your own water, you reduce your reliance on municipal water to become more self-sufficient as you cultivate the green landscape of your dreams (no matter what type of climate you live in)  

During the Water Harvesting Summit, you’ll learn techniques from our experts for harvesting your own water, from rainwater to greywater. You’ll learn how to build healthier soil that can hold more water. And you’ll learn some of our favorite efficient and effective garden-watering techniques.

DATES: Daily July 13th-15th, 2022 from 2pm to 5pm Pacific Time (replays available). 

LOCATION: Online. Links to attend will be sent to your inbox each day of the Summit (after you sign up)

Your Host:
Farmer Greg Peterson

Farmer Greg is the creator and your main host for the Water Harvesting Summit. You will find him introducing each speaker, jumping online for live Q&As daily, and sharing a few presentations.
Farmer Greg has been digging his toes into the earth, listening to the plants, and experimenting wih progressive permaculture techniques in his yard for over 40 years. His 1/3-acre home in Phoenix, AZ has been converted into an entirely edible landscape open to the community for tours and classes, and his fruit tree program has resuted in the planting of over 10,000 fruit trees. Greg's mission is to show others that they too can realize the power, joy and deliciousness of urban farming! Greg received his Master's degree in Urban and Environmental Planning from Arizona State University, and has since taught at a trade school and even returned to his alma mater to teach Sustainable Food and Farms. He started UrbanFarm.org to build a community for urban farmers and home gardeners around the world to come for inspiration, education, and advice. His podcast, The Urban Farm Podcast, has been so fun and successful that he has decided to expand his reach to even more people by offering virtual Summits.

Your Co-Host:
Janis Norton

Janis is an integral part of The Urban Farm Team and will be co-hosting this summit with Greg. You will find her helping out in between the presentations AND leading a presentation on wood chips
Janis's expertise revolves around community and education. She has more than two decades of experience managing youth programs and training both the youth and their leaders. She has a great passion for helping others learn new skills. Wanting to take her own education further, she pursued degrees in Chemistry and Sustainability and snagged an internship with The Urban Farm. There she became motivated to learn all she could about growing food while using her project management skills to help facilitate The Urban Farm’s events including the 2nd Annual Great American Seed Up. Now that she’s found her calling and knows she is making a difference in her community, there is no stopping her!
