I’m wanting examples of ecological water management (net zero water) precedents and policies that encourage such practices.

Code Innovations Database is a technical resource for precedents of high-performance green building innovations.

Check out the International Living Future Institute’s new case studies about projects that found permit pathways for ‘net positive water systems’:


Greywater Action has excellent information on codes and policies related to graywater reuse, rainwater harvesting, and composting toilets in the United States.

The National Onsite Wastewater Recycling Association has created a performance based model code supported by the US EPA. NOWRA’s model code does not follow exactly the same performance standards Recode prefers but provides excellent guidance on implementing design standards and a verification regime.

The Green Center in Cape Cod conducted research as the New Alchemy Institute in the seventies and currently supports various ecological efforts.

Economics of Change: Integrated Policy Approaches to Unlocking the Value of a Restorative Built Environment by Theddi Wright Chappell, (Sustainable Values Inc), Stuart Cowan, Ph.D. (Autopoiesis LLC), Richard Graves (International Living Future Institute), and Jason Twill (Systems Economics LLC).

The US Green Building Council (USGBC) has several useful documents to check out:

The Guardian did a great article, Bodies into food and sewage into beer: you are the hot new thing in recycling, on ecological sanitation and highlighted Rich Earth Insitute’s research into reusing urine as a fertilizer.

“Every day you’re pissing away a loaf of bread,” says Noe-Hays. “The US could meet a quarter of its fertilizer needs just by reclaiming all the urine produced in a year.”

Recommendations for Improving the CALGreen Code is a summary and discussion from April 2015’s “Green Codes for California: A Progress Report and Recommendations from the LEED and CALGreen user group.”

The International Living Future Institute’s has shared research reports and roadmaps for fundamentally changing our approach to regulating water in our built environment.
