Orange County works with U.S. Army Corps to bolster groundwater supplies

To reduce dependence on water imported from Northern California and the Colorado River, the Orange County Water District (OCWD; Fountain Valley, Calif.) is collaborating with the U.S. Army Corps of Engineers (USACE) to maximize the area’s stormwater capture capabilities. From July 2016 through January 2017, the height of California’s flood season, Orange County experienced rainfall […]

Tree hydration system made from recycled diaper material minimizes stormwater runoff

Using watering bags to nurture young trees can help ensure a moist soil environment as the plants develop root structure. But standard watering bags require constant refills, and do little to deter stormwater runoff pollution. However, a new product made from the same material used in disposable diapers can catch and retain rainwater before releasing […]

Urban design software matches abandoned land parcels to green infrastructure projects

When Nicholas de Monchaux, an associate professor of architecture and urban design at the University of California, Berkeley, began his “Local Code” project almost 7 years ago, he set out to address two of the most pressing problems facing modern cities. Local Code uses open-source software to match thousands of abandoned city lots with site-specific […]

Researchers seek to unlock stormwater to alleviate Texas drought

Researchers at the University of Texas at San Antonio (UTSA) received a $42,800 grant from the Greater Edwards Aquifer Alliance (San Antonio, Texas) and San Antonio River Authority to support research that would treat stormwater so that it can be used by San Antonio. According to a USTA press release, San Antonio deals with both […]

Stormwater infiltration pilot project in California aims to boost aquifer recharge

A pilot project is testing the feasibility of using specially-designed ponds for catching stormwater and facilitating groundwater recharge in the Pajaro Valley region of California’s Central Coast, where aquifer levels are dwindling from overuse brought on by severe drought conditions. Andrew Fisher, a University of California, Santa Cruz hydrogeologist who is leading the project, built […]

National Academies Report Calls for Stormwater and Graywater Use Guidelines

In the face of drought and major water shortages, the U.S. increasingly is turning to alternative water sources like stormwater and graywater. However, guidelines and research on the risk of these water sources to public health and the environment are needed to support decisions for safe use, says a new report from the National Academies […]
