We are doing a jack and bore in Phoenix, Arizona. City of Phoenix is concerned about the life expectancy of 48" Steel Casing Pipe. We are thinking of using the casing pipe as a storm drain. The City is requesting a life expectancy of 75 years. Field resistivity of the soil is 4711 (ohm/cm). Will a 1/2" thick casing pipe be thick enough?
