Abstract: The hydrological cycle, complicated through urbanization, results in alterations to both the quality and quantity of available water. In comparison to a natural environment, runoff and groundwater recharge volumes in urban areas are greatly modified. However, detailed monitoring, quantification and assessment of these variables are limited. The objective of this research is to estimate the potential groundwater recharge in an urban watershed. Research was conducted using observation, calculation and modelling of the urban hydrological cycle. Modelling was conducted using the SUEWS (Surface Urban Energy and Water Balance Scheme) to provide an additional estimate of potential groundwater recharge. Potential groundwater recharge amounts ranged from 143 to 187 mm over the six month study. Chemical and microbiological water tests were utilized to investigate potential water sources. Results indicate human sewage contamination signifying potential sewage leakage. Urban recharge and associated contamination risk provide insight into the overall health of local surface water sources
