In the face of historic challenges -- climate change, revenue fluctuation, staff turnover, regulations – smart water utilities are recognizing advanced technology as an opportunity to equip staff with the “best possible access to information to increase individual operational efficiencies and empower ability to make correct and timely decisions.” 1 Integrated control systems often incorporate a SCADA system for wide area monitoring and control of operations. “These operations might include remote pumping stations, wastewater collection, water distribution, PLCs, sewer diversion, water irrigation, wet weather overflow, and weather monitoring .
