Groundwater is a valuable source of drinking water and projects that manages groundwaterneed to prevent complications on the water’s characteristics. In an infrastructural project,groundwater reduced from elevated levels of nitrate needed to be recharged into the aquifer inthe area. This study aimed to describe important parameters to consider while performingartificial recharge. To fulfil the aim four research questions were answered; 1) What are thesurficial deposits in the area and how do they affect infiltration? 2) Are there any geologicalstructures that can influence the flow pattern due to infiltration? 3) What is the flow directionpattern in the area and how does it affect infiltration? 4) How does the infiltration attemptinfluence the groundwater levels and flow pattern in the aquifer? Previous literatures werestudied to find parameters that could affect the choice of location for an infiltration attempt.These parameters were used in Pugh’s concept selection and the most suitable location wasfound. To evaluate the attempt the groundwater levels were measured before and afterinfiltration to locate any local rise in groundwater levels. The results showed no rise ingroundwater levels that would change the flow pattern in the area and the location proved tobe suitable for infiltration in the future. The surficial deposits, groundwater flow direction andthe bedrock topology in the area proved to be important parameters that limited the possiblelocations for groundwater recharge. Future studies need to include these parameters and takeeconomic factors and land use into account to find appropriate infiltration locations.
