Abstract: The City of Kalamazoo, Michigan, has constructed induced recharge facilities at sites of several of its twenty-one well fields as part of a program for supplying potable water to Kalamazoo and surrounding communities. One of these well fields (Station No. 9) was the subject of a series of extensive field experiments conducted by the U.S. Geological Survey in cooperation with the City in 1959. This well field has produced an average of 5 million gallons per day since 1950 from 12 production wells. The wells are installed to a depth of about 160 feet in an artesian aquifer of glacial drift which can be separated into three general units - a lower aquifer, an intervening confining layer, and an upper aquifer. The principal effect of induced recharge is to reduce the amount and rate of drawdown which results in lower pumping costs and increased withdrawal rates during periods of peak demand. This paper summarizes the results of the study conducted in 1959 and describes the performance of the well fields since that time.
