In October, 2022, of the twenty six bills listed below, Gov. Jerry Brown signed into law seve of the twnety six water related bills listed further down this article. 

Chris Gray of Marvel Golf Club in Benton, KY, winner of Rain Bird's second annual Intelligent Use of Water Award, developed a water-harvesting program that captures not only rain, but also run-off from roads, and the waste discharge from the 513 residences surrounding his course.




Cistern outlet controls (to prevent catastrophic water loss)


Infinitely variable natural water diversion control


Easy start, long duration siphon with integral check valve, funnel, air relief, dissolved gas and air reservoir (parts of the house plumbing are under negative pressure)

Art Ludwig was hired by Huehuetortuga, a new landholding added to the ecological arts community of Huehuecoyotl, to intertwine water, wastewater, energy systems and landscaping in a diverse and extreme environment at 7000 feet elevation with an average annual rainfall of four feet eight inches, and no rain for eight months. The development has no water supply during the dry season, water is either stored or brought in by truck. To maximize water use and insure water independence through the dry season, the site now includes rainwater harvesting, surface water diversion, efficient fixtures, four greywater systems, constructed wetland, edible landscaping, a composting toilet, solar hot water, and hydro-electric power.



Guidelines for the Safe Use of Wastewater, Excreta and Greywater: Volume 2: Wastewater Use in Agriculture

World Health Organization

Volume 2 of the Guidelines explains requirements to promote safe use concepts and practices, including health-based targets and minimum procedures. It also covers a substantive revision of approaches to ensuring the microbial safety of wastewater used in agriculture. It distinguishes three vulnerable groups: agricultural workers, members of communities where wastewater-fed agriculture is practiced and consumers. It introduces health impact assessment of new wastewater projects.


Guidelines for the Safe Use of Wastewater, Excreta and Greywater: Volume 3: Wastewater and Excreta Use in Aquaculture (2006, 158 pp, Book)

World Health Organization

Volume 3 of the Guidelines informs readers on the assessment of microbial hazards and toxic chemicals and the management of the associated risks when using wastewater and excreta in aquaculture. It explains requirements to promote safe use practices, including minimum procedures and specific health-based targets. It puts trade-offs between potential risks and nutritional benefits in a wider development context. Special reference is made to food-borne trematodes.

Cleaning products and other items to avoid that could end up in wastewater.


Ecological Sanitation (2004, 147 pp, PDF)

Winblad, Uno et al. Stockholm Environment Institute

“This book is about seeking new solutions in the form of "ecological sanitation". The book discusses what is currently known about ecological sanitation systems, their strengths and weaknesses. It gives advice on how to make such systems work with regard to the selection, design and management of devices as well as about the promotion and support aspects so necessary to their success.”

Waste Stabilization Ponds and Constructed Wetlands (Webpage and PDF)

United Nations Environment Programme, Division of Technology, Industry and Economics, and the Danish International Development Agency

Artificially Constructed Wetlands are proving to have enormous value in terms of efficiency, low cost, simple operation and maintenance when compared to waste treatment plants. The page includes information and a downloadable design manual.



Constructed Wetlands in the Sustainable Landscape (1999, 288 pp, Book)

Craig Campbell and Michael Ogden, Wiley Publishers

Constructed wetlands are gaining worldwide acceptance as effective, low-cost, and low-impact alternatives to unsightly, high-impact wastewater treatment facilities. … Constructed Wetlands in the Sustainable Landscape is the first book to integrate aesthetic design and planning issues with the technical aspects of wetlands engineering.


Waste Stabilization Ponds and Constructed Wetlands Design Manual (59 pp, PDF)

Danish Technological University (DTU) and the University of Dar Es Salaam, Tanzania.

Waste Stabilization Ponds (WSP) and Constructed Wetlands (CW) have proven to be effective alternatives for treating wastewater, and the construction of low energy-consuming ecosystems that use natural processes, in contrast to complex high-maintenance treatment systems.


Commercial Fats, Oil and Grease (FOG) Reduction Program (Webpage)

Public Utilities Commission, San Francisco, California

Webpage contains PDF’s of brochures and checklists listing BMP’s for restaurants’ handling of fats, oil and grease and their impacts on sanitary and storm sewers.


Storm-water runoff is the No. 1 cause of water pollution in suburban and rural areas. But in Portland, Oregon, an innovative system of curbs,
gutters, roofs and rain gardens diverts runoff and sharply cuts water pollution - and is spawning a major tourist attraction.

Let's take a good look at what is and isn't working?  For the Cal EPA offices, waterless urinals did not.  And here's why.


SACRAMENTO, CA - The California Environmental Protection Agency has ended a six-year experiment with waterless urinals in its 25-story headquarters building, touted by the Schwarzenegger administration as the "greenest" high-rise in the nation.

When a limited number of waterless fixtures were first installed on four floors in 2003, the building's management projected annual water savings of 1 million gallons when the entire building was outfitted three years later.
