Abstract

This paper evaluates the performance of a groundwater well by analyzing its well development, pump setting scenarios, and production capacity. The well's condition is assessed by calculating its well development factor, and pump setting analysis is conducted to determine the best pump position for maximum yield and safe drawdown. Pumping tests are performed to measure water levels and predict future well performance, sustainability, and maintenance needs. The specific capacity of the well equation is used to describe productivity, and steady-state drawdown values are calculated for four different pumping rates. The well development factor is excellent, and well efficiency values range from 82% to 72% for flow rates of 22.6 L/s to 39.5 L/s. The optimal discharge rate is calculated, and the appropriate pump location is determined to accommodate the desired discharge rate and water table decrease. The results provide valuable information for future well management and maintenance planning.
