Citation:
Kraemer, S. Assessment of Dry Wells for Stormwater Capture and Aquifer Recharge in the Arid and Semi-Arid Southwest. U.S. E.P.A.'s Water Reuse, Water Scarcity, and Drought Grants Progress Review Meeting & Webinar, webinar, December 07, 2017.
Impact/Purpose:
EPA is hosting a two-day conference and webinar highlighting research from the Human and Ecological Health Impacts Associated with Water Reuse and Conservation Practices and National Priorities: Systems-Based Strategies to Improve the Nation’s Ability to Plan and Respond to Water Scarcity and Drought Due to Climate Change Request for Applications (RFA).
Description:
GOAL: to evaluate the utility of innovative, distributed, low impact development (LID) infrastructure and best management practices (BMPs) for wet weather capture and drinking water aquifer recharge in the arid and semi-arid southwestern USA OBJECTIVES: Design, build, monitor the performance of systems of BMPs (capture, storage and settling, infiltration, recharge) for the diversion of wash flow, urban and rooftop runoff, recycled wastewater conveyance, into storage, pre-treatment, and focused recharge through infiltration galleries (wider than deep) and dry wells (deeper than wide) Utilize a step-wise and progressive computer modeling approach that includes overland, vadose zone, and groundwater flow and water quality, for design and evaluation Explore scenarios for upscaling recharge system performance to evaluate net zero water and aquifer sustainability and resilience as measured by a sustainable yield without negative impacts Document experience with the dry well system prototype at Fort Irwin military installation with ambition to transfer technology to the urban metroplex (e.g. Los Angeles) METHODS: Combination of field observations and computer simulation modeling
