Abstract

Urban water management systems connect water supply, wastewater, and stormwater infrastructure. In California, over 400 water supply agencies provide water to 36 million people living in cities and suburbs. The wastewater generated by homes, businesses, and industrial facilities is managed by hundreds of wastewater collection, treatment, reuse, and recovery systems. A network model of system-level connectivity to water supply and wastewater infrastructure was developed to simulate how changes in water demand affect downstream flows in wastewater collection, treatment, and reuse systems. The model was created to estimate potential impacts to flow in wastewater management systems from water use efficiency and conservation by linking where water is used to the collection systems and wastewater treatment/reuse facilities where it is managed and recovered. The model was used to support regulatory rulemaking for California’s “Making Water Conservation a Way of Life” associated with Assembly Bill 1668 and Senate Bill 606 (AB 1668-SB 606). Details of the model’s development and use were presented in public workshops in December 2021 and May 2022, which can be found at this link: https://www.waterboards.ca.gov/water_issues/programs/conservation_portal/regs/water_efficiency_legislation.html
