Water purification and wastewater facilities are critical for the population of the regions and municipalities they serve. Safe and clean water is essential for public health, ecosystem protection and economic strength. The treatment of black water and re-capture of gray water is also important for population safety and conservation efforts. At the same time, new developments add to the already long list of challenges, including intra-agency mutual aid agreements, changing operational paradigms and new regulatory compliance standards such as the AWIA. Supporting these important functions requires secured information technology (IT) and operational technology (OT).
