System modeling, optimization, and analysis of spreading basins receiving stormwater and recycled water for enhanced water resilience
Abstract/Contents
- Abstract
- Increasing pressures on existing water systems are leading urban water managers to explore new options for enhancing water supply resilience. In this context, more cities are considering infrastructure systems that use stormwater and recycled water to augment groundwater recharge through spreading basins (groundwater recharge ponds). These systems may represent cost-effective opportunities to enhance and diversify water supplies. However, technical questions remain about 1) how these systems can be made affordable—a primary barrier commonly cited for both recycled water and managed aquifer recharge projects, and 2) the effect of regulatory constraints on the design of the water recycling process. To address this need, this dissertation developed a specialized system model for identifying optimal infrastructure systems that deliver advanced treated recycled water to existing stormwater spreading basins. The resulting systems simultaneously minimize infrastructure life cycle costs and maximize groundwater recharge while satisfying engineering and regulatory constraints. Applying this model to case studies of Los Angeles, CA, this dissertation demonstrates the trade-offs of different system designs with respect to cost, energy use, and total organic carbon, a regulated water quality parameter for groundwater recharge with recycled water. For example, compared to existing conservative planning approaches, more flexible planning approaches that account for the greater dynamic availability of stormwater can reduce system costs by 5--20%. In addition, compared to the membrane-based treatment train predominantly used to produce recycled water for potable reuse, ozone-based and hybrid treatment can reduce system costs up to 35%. In sum, this modeling framework can inform water plans and potentially improve the resilience of urban water infrastructure.
