Design, Development and Evaluation of Artificial Well Recharging System for Groundwater Enhancement

Abstract

An artificial well recharge system model was designed and constructed near open well for groundwater enhancement. The filtration efficiency of primary filter was determined and found to be in tune of 64 to 70% and for main filter 90 to 94%. During the year 2011, 630 mm of rainfall produced 203 mm of runoff which is 32.21% of the rainfall. Similarly, during the year 2012, 678 mm of rainfall generated 152 mm of runoff i.e. 22.41% of the rainfall. The total rainfall received during the year 2013 was 1131 mm and it produced 407 mm runoff. The water level in the well was recorded periodically at an interval of 15 days to observe the groundwater level fluctuation. Comparison of water levels of 2011 to 2013 indicated that there was an increase in water level varied between 0.3 m and 3.4 m due to artificial well recharging.
