Increased pressures on California’s water supply, including from population growth and intense periods of drought exacerbated by climate change, are leading to the overuse of surface water and groundwater. But with existing technology and conservation methods, the state can take vital steps to improve its resilience to drought and plan for a more sustainable water future. This issue brief, produced in collaboration with the Natural Resources Defense Council, is a statewide analysis of the potential for improved efficiency in agricultural and urban water use, water reuse and recycling, and increased capturing of local rainwater.

Energy Down the Drain: The Hidden Costs of California’s Water Supply analyzes the connections between power and water resources in California. The report presents several key findings: 1) water conservation lowers energy use and energy bills, 2) water recycling is a highly energy efficient water source, 3) retiring agricultural land may increase energy use if the water is transferred to other agricultural or urban uses, 4) Retiring agricultural land can save energy if the water is dedicated to the environment, and 5) diverting water above dams costs an enormous amount of power and money. Based on these findings it is recommended that decision makers better integrate energy into water policy decision-making, as well as give water conservation higher priority.

Assessing the Return on Investment in Watershed Conservation applies a return on investment (ROI) framework to a watershed conservation project in Santa Catarina, Brazil. The framework involves quantification of the relationships between 1) intervention, 2) ecosystem structure, 3) ecosystem function, 4) ecosystem service, 5) benefit, and 6) values and program cost. The report illustrates that restoring source watersheds is a cost-effective way to reduce drinking water treatment costs, improve water supply resilience, and protect biodiversity. The ecosystem services quantified in the study include sediment concentrations at water treatment intake, which when reduced can lead to avoided peak season water loss, avoided use of chemicals, avoided dry sludge landfilling, and avoided pumping. The report also includes costs for landowner engagement and interventions, as well as land rentals.

Bay Area Project Tackles Sea-Level Rise and Water Quality reports on a creative adaptive management strategy that has been applied to a section of the San Francisco Bay to help with sea-level rise and improve water quality. The strategy is called a “horizontal levee,” which uses vegetation on a slope to break wave impact. In the article they cite benefits for salt marshes that are at risk for disappearance due to sea-level rise, and benefits to water quality as a result of naturally occurring soil microbes uptaking nutrients in the wastewater delivered to the levee. Additionally, water that passes through the levee exhibits reduced pharmaceutical content.

The report also includes case studies from throughout the U.S. that illustrate the multiple benefits produced from onsite non-potable water systems, including system resilience, diversification of water supplies, stormwater management and pollution reduction, compliance with policy and regulatory requirements, reducing capital costs, enhancing environmental and community facilities, providing opportunities for public-private partnerships, and technology advancement.

Green infrastructure and its catchment-scale effects: An emerging science provides an overview of past research conducted on the impacts of green infrastructure (GI) and low-impact development (LID) on water quality (i.e. runoff and discharge) and water quantity at localized scales. The report also presents considerations for scaling GI and LID research to the catchment-scale, advances and findings in scaling efforts, and the use of models as tools for scaling.

Environmental Farming Act Science Advisory Panel – Bi-Annual Report (2011-2013) is a resource developed by the Environmental Farming Act Science Advisory Panel and organized by Secretary of the California Department of Food and Agriculture (CDFA). The advisory panel aims to review the impact of agriculture on the environment and encourage agricultural practices with environmental benefits by providing incentives and modifying environmental regulations. The environmental benefit categories established by the advisory panel include: wildlife habitats; nutrient cycling; food, fiber, and fuel production; recreation and cultural; soil structure, formation, and fertility; biodiversity conservation; water cycling; atmospheric gas/climate regulation; pest control; pollination services; and water quality.

Green Stormwater Infrastructure Economics in the Boise Urban Area (2015) examines the economics of green versus grey infrastructure in Boise, Idaho. Infrastructure projects analyzed include bioretention, trees with suspended pavement systems, permeable pavement, bioswales, conventional trees without suspended pavement systems, and conventional paved alleyways. Biophysical services and social benefits are compared to the alternative (i.e., status quo) option to determine the differences in services. The biophysical services identified include waste absorption/pollutant reduction, groundwater recharge, carbon sequestration, temperature reduction, and biodiversity/habitat provision. The social benefits identified include clean drinking water, water supply, clean air, aesthetics and recreation, pedestrian and vehicle safety, heat island effect, education and community engagement, and compliance credits.

The Value of Green Infrastructure: A Guide to Recognizing Its Economic, Environmental and Social Benefits is an in-depth framework for evaluating the multiple benefits of green infrastructure projects, including green roofs, tree planting, bioretention and infiltration, permeable pavement, and water harvesting. The framework provides methodologies for valuation of water, energy, air quality, and climate change-related benefits, as well as a qualitative discussion on community livability and public education benefits.
