It is required to dewater a construction site 80 m by 80 m. The bottom of the construction will be 1.5 m below the initial water surface elevation of 90 m. Four pumps are to be used in 0.5-m diameter wells at the four corners of the site. Determine the required pumping rate. The aquifer has T = 1600 m^2/day and the wells each have a radius of influence of 600 m.
