RICH EARTH
SUMMIT

For Urine Diversion and Source Separation

Advancing circular sanitation for clean water and sustainable agriculture. Together, we can pee the change! 

The Rich Earth Summit is the annual, global gathering for urine diversion, compost toilets, and other source separation systems that advance sustainable and equitable nutrient cycles. The Summit explores how nutrients in human “waste” can be reclaimed as a valuable resource for farms instead of becoming costly watershed pollutants. 

Each year, the Summit brings together a growing community of researchers, nonprofit organizations, entrepreneurs, farmers, educators, engineers, municipal leaders, policymakers, and advocates to share ideas, collaborate, and grow a fertile future through circular sanitation systems. 

 

The 2026–2027 Rich Earth Summit series includes two complementary events. Join us online this fall to hear about research and projects from around the world, then continue learning on Cape Cod next spring at our in-person US Summit, for deepening connections with watershed leaders and the ecological sanitation community. 

Global Virtual Summit

November 4-6, 2026

Connect with participants from around the world for three days of presentations, panel discussions, workshops, and networking. Learn about the latest research, hear lessons from pilot projects, discover emerging technologies, and build the partnerships needed to accelerate the transition toward circular sanitation systems. 

US In-Person Summit

Spring 2027 (exact dates TBC), Cape Cod, MA

Join national and state leaders on Cape Cod, where severe nutrient pollution is driving momentum for urine diversion as an affordable, scalable solution for watershed protection. Together we’ll digest gleanings from the Global Virtual Summit and apply them to a region leading the nation in municipal-scale urine diversion. Come to exchange strategies across nutrient-impaired watersheds, explore planning approaches, and see pilot projects firsthand while connecting with the ecological sanitation community through workshops and exhibits. 

Thank you to our Summit sponsors for helping make this event possible!
