Factors affecting the cost of managed aquifer recharge (MAR) schemes

摘要: Managed aquifer recharge (MAR) is an important technique for improving groundwater and maintaining levels. There are many examples from around the world that demonstrate advantages of managed recharge. Despite numerous benefits demonstrated MAR, uptake has been lower than expected. The financial economic performance MAR a key determinant its global uptake. few studies characteristics different kinds schemes. This study contains analysis data 21 schemes five countries. Although highly heterogeneous, it possible to draw some conclusions about factors affect costs storing water underground recovering use. vary substantially. Schemes using infiltration spreading basins untreated relatively cheap. wells, bores expensive infrastructure costly. When advanced treatment needed, this involves significant extra costs. Other scheme include range objectives be met, frequency use scheme, hydrogeological conditions rates well yields, source end stored underground.
