Water hammer in an irrigation district pipeline is typically caused by sudden changes in turnout flow rates. A sudden shutoff of a booster pump, or a rapid closure of a turnout valve, can potentially cause surge damage. The problem occurs if the pressure exceeds the pressure rating of the pipeline. As pipes age, their pressure rating typically declines. This report describes three different solutions that utilize a combination of these techniques/devices to provide district pipeline protection from water hammer.
