Electronic system locates leaks in irrigation mainProblem: The Salt River Project maintains a 1,300-mile irrigation system for the Phoenix metropolitan area. Recently, a 27-inch gravity-fed raw water concrete irrigation main was thought to be leaking. After previous inspections, Electro Scan was invited to evaluate the pipe to pinpoint any leaks.Solution: Electro Scan technology accurately locates and measures leaks without operator interpretation using a probe that emits a low-voltage, high-frequency electric current to assess the pipe wall. Traveling at 45 to 60 feet per minute and taking readings every 14 milliseconds, the probe collects 10,000 to 20,000 data points every 300
