We were inspired by Central City Concern’s visualization of the rules guiding (and limiting) reuse of water and nutrients in Oregon, to make our own now that rules have changed. Ever wondered what permit you need for a site built composting toilet? Or how graywater and blackwater are regulated? Or just really like graphical representations of complex systems?
