This article discusses a situation in Hillsboro, Oregon, where numerous high‐tech firms were experiencing a gradual reduction in service pressure over time. The city's water department decided the best long‐term solution was to create a separate, higher‐pressure zone in the industrial area. They identified six locations for installation of pressure‐reducing valve (PRV) stations that automatically reduce a higher inlet pressure to a steady, lower downstream pressure, regardless of changing flow rates or varying inlet pressure. The resulting design created a high‐pressure loop that surrounds customers in the designated high‐pressure zone. Safe conditions, continuous flow and installation problems are discussed, along with smooth startup procedures.
