全世界各区域都采用了有管理的含水层补给，以改善水的数量和质量。此外，污染场地的处理往往需要注入水和特定的添加剂，以支持自然衰减过程。Händel等人（J Hydrol 517：54-63，2014.土井： 10.1016/j.jhydrol.2014.05.003 ）采用了一种新的补给方法，采用具有成本效益的小直径威尔斯井。数值研究，除其他外，调查地下结构对注射过程的影响。并与渗滤池进行了比较。为了缩小理论工作与中期注入清洁沃茨的技术实际应用之间的差距，并提供小直径井回灌的实验验证，在德国萨克森的试验场皮尔纳进行了两次使用小直径井（1“内径）的注入试验。在第一次短期试验中，采用逐步增加的注入率，结果表明井水位仅略有增加。在第二次测试中（使用同一口井），连续注入地下水14天。0.75 l/s的恒定注入速率导致900 m3的再充水量，显示了这种威尔斯井用于清洁水渗透的高性能潜力。
Managed aquifer recharge has been used for various regions worldwide to improve water quantity and quality. Furthermore, contaminated site treatment often requires injection of water together with specific additives to support natural attenuation processes. Händel et al. (in J Hydrol 517:54–63, 2014. doi: 10.1016/j.jhydrol.2014.05.003 ) introduced a new recharge approach, applying cost-efficient small-diameter wells. Numerical studies were applied, among others, to investigate the effect of subsurface structures on injection process. Besides this, a comparison with an infiltration basin was made. To close the gap between the theoretical work and the practical use of this technique for medium-term injection of clean waters and to provide an experimental validation of the small-diameter well recharge, two injection tests using a small-diameter well (1″ inner diameter) were performed at the test site Pirna, Saxony, Germany. In a first short-term test, stepwise increasing injection rates were applied and showed only a slight increase in well water levels. In a second test (using the same well), groundwater was injected continuously for 14 days. The constant injection rate of 0.75 l/s resulted in a recharged water volume of 900 m3, showing the high-performance potential of such wells for clean water infiltration.
