[h=Energy & cost savings]3[/h] While total green design overhaul may seem like a pipe dream* automation can help plants achieve low-cost operational improvements* which can unlock hidden energy-saving opportunities. Take the water and wastewater industry as an example. According to General Electric* in the U.S. alone* an estimated 2.1 trillion gallons of water are lost annually due to water supply infrastructure challenges* such as main breaks* pipe bursts and unidentified leaks. The pipes* valves and other equipment in many wastewater pumping stations and treatment plants have been around for 50 years or more. In addition* mandates for lower water consumption in many areas combined with increasing use of flushable wipes and other solid materials puts additional strain on these systems. As pumps need to work harder to transport higher loads with less water* the ability to monitor leaks and optimize system pressure and flow rates can lead to potential energy and cost savings.


Various process sensors and transmitters along with remotely actuated control valves can be used to help reduce leaks that lead to water and energy waste* resulting in a more efficient and lower cost system. With the addition of remote communication capabilities and automatic monitoring* performance data can be gathered and stored* which can be used to track and proactively address issues before they result in costly shutdowns.
