“…For example, ASR can reverse declining groundwater levels [45,46], which have previously been an issue for the Carrizo-Wilcox Aquifer [31]. In addition, water stored in the subsurface is also subject to less leakage than surface reservoirs and has no evaporative losses [47,48]. In the San Antonio-Nueces coastal basin, mean evaporative losses amount to 148 cm per year, thus storage of water without evaporation losses would preserve a large quantity in Texas.…”

Abstract:The ISI (Institute for Sustainable Infrastructure) Envision rating system is designed to be a comprehensive sustainability assessment that can be applied to a wide range of infrastructure projects, including water supply. With water supply resiliency, a prominent concern in many arid and semi-arid regions, the implementation of a water sustainability metric would be beneficial to both regulators and planners. This review seeks to assess the merit of applying Envision to water infrastructure projects specifically designed to enhance supply resiliency by retroactively rating the San Antonio Water System (SAWS) Twin Oaks Aquifer Storage and Recovery (ASR) project. In this review, we find that the novelty and innovation inherent in ASR is largely overlooked by Envision, which often does not evaluate sector-specific concepts. Furthermore, the project-oriented focus of Envision does not analyze water supply systems, or any infrastructure system, as a whole. This paper proposes that a water specific sustainability index be used in conjunction with Envision, to more specifically address concerns for water supply.

“…Not only are limited water supplies augmented, but economic costs to municipalities and users are often reduced. A cost-benefit analysis of an aquifer recharge program in the Las Vegas Valley, Nevada, U.S.A. found that members of the groundwater management program had an annual savings of $700 per member (Donovan et al 2002).…”

“…The issue of finance is well illustrated by the Las Vegas, Nevada (USA) aquifer recharge system, for which Donovan et al [55] provided a cost-benefit analysis for non-municipal water users. The Las Vegas aquifer system recharges an historically overdrafted alluvial aquifer with seasonally available excess treated surface (Colorado River) water, with the primary goals of increasing available water resources, slowing or reducing the decline in water levels, and reducing the rate of land subsidence.…”

Managed aquifer recharge (MAR) technologies can provide a variety of water resources management benefits by increasing the volume of stored water and improving water quality through natural aquifer treatment processes. Implementation of MAR is often hampered by the absence of a clear economic case for the investment to construct and operate the systems. Economic feasibility can be evaluated using cost benefit analysis (CBA), with the challenge of monetizing benefits. The value of water stored or treated by MAR systems can be evaluated by direct and indirect measures of willingness to pay including market price, alternative cost, value marginal product, damage cost avoided, and contingent value methods. CBAs need to incorporate potential risks and uncertainties, such as failure to meet performance objectives. MAR projects involving high value uses, such as potable supply, tend to be economically feasible provided that local hydrogeologic conditions are favorable. They need to have low construction and operational costs for lesser value uses, such as some irrigation. Such systems should therefore be financed by project beneficiaries, but dichotomies may exist between beneficiaries and payers. Hence, MAR projects in developing countries may be economically viable, but external support is often required because of limited local financial resources.
