A municipal wellfield is designed to consist of fivewater-supply wells, each rated at 16 litre/s. The wells are located100 m apart along a north-south line and fully penetrate a 20mthick confined aquifer that has a transmissivity of 1000m2/day. .Estimate the maximum drawdown 500m west of the centre well assumingthat all wells are 40cm in diameter and the radius of influence ofeach well is 800m. [15 Marks] 4b. If the calculated drawdown valueis considered too low, propose 3 design options to ensure anincreased drawdown.
