At Risk: Public Supply Well Vulnerability Under California’s Sustainable Groundwater Management Act
Community water systems in California’s San Joaquin Valley face a host of challenges that threaten the safety and reliability of drinking water, including pollution, periodic drought, and chronic groundwater overdraft. Moreover, shallow wells, some of which serve community water systems, are vulnerable to short-term and chronic declines in groundwater levels. For example, during the 2012-2016 drought, many domestic wells and some public supply wells went dry.
The Impacts of the Pandemic Remain for Small Water Systems and Customers In-Debt
In the U.S., the vital responsibility of continuing safe water supply during the pandemic is decentralized, spread among nearly 50,000 community water systems. More than 45,000 of these are small community water systems (SCWS), serving fewer than 10,000 people each. Together, SCWS provide water to more than 53 million people — 18 percent of the national population — across urban and rural areas, on tribal reservations, in the midst of larger utilities in huge metropolises, and in growing communities.
What Role Should Onsite Water Reuse Play in Silicon Valley Water?
Water systems in most large urban areas like California’s Silicon Valley are linear and highly centralized. Water is cleaned at a central treatment plant, distributed to homes and businesses through a vast and decades-old system of pipes, used once, and then returned through another set of pipes to a wastewater treatment plant, before being discharged into a nearby waterway like the San Francisco Bay.
The Role of Onsite Water Systems in Advancing Water Resilience in Silicon Valley
California’s Silicon Valley faces a host of water challenges. The region’s water and wastewater infrastructure are aging, and in some cases are nearing the end of useful life. Continued growth and development are putting additional strains on the region, and climate change is adding to that burden through sea level rise, more intense storms, and more severe droughts. These challenges present risks but also an opportunity to rethink the design, configuration, and operation of water and wastewater systems.
