Evaluating reuse as a drought-resilient water supply alternative
Garver assisted the City of Lawton, Oklahoma, in evaluating drought-resilient water supply alternatives to help diversify and expand the City’s water supply portfolio. Our team worked with City staff to outline an emergency response plan and produce a feasibility study that summarized the results of the water supply evaluations. As part of the alternatives assessment, Garver evaluated potential non-potable applications to trim peak demands and identified reclaimed wastewater for potable use as classified in two different categories: indirect potable reuse (IPR) and direct potable reuse (DPR), and a new groundwater supply from the Arbuckle Timbered Hills Aquifer. As the committee chair for potable reuse projects in Oklahoma, Garver worked with the Oklahoma Department of Environmental Quality and Oklahoma Water Resources Board for several years to develop regulations for practicing IPR, requiring testing of treatment processes prior to implementation.
