Abstract
The purpose of this study is to help water utilities make more informed decisions about water reuse opportunities. We develop a new system model to optimize capture, storage, treatment, and conveyance of urban stormwater to infiltration ponds to supplement groundwater recharge. We compare the unit life cycle costs for different stormwater treatment trains through case study of Santa Clara County, CA. Key Findings include: a) There are opportunities to divert 12,000+ AFY from Coyote Creek and deliver to Los Gatos Recharge Ponds. This volume is >10x larger than volumes in previously identified projects. b) There is a highly nonlinear relationship among system cost, storage volume, treatment train selection, and total water deliveries to Los Gatos. c) Depending on system size and treatment train design, costs range from 2,000 – 7,000 $/MG, with substantially lower production costs than seawater desalination. d) The incremental benefit of storage is small between 0 – 10 MG.
