Isolating Flow Paths to Non-essential or Non-operating Equipment

Unnecessary demand is placed on the pumping system when the pumping system operates all of the time, even when flow demands may be variable and intermittent or not required at all. By isolating users with such demand characteristics from the facility's main pumping system, and developing a separate system that can more efficiently respond to their specific demand, important gains can be achieved in the overall system performance.
