Reliability is paramount to the monitoring and control of water/wastewater facilities. With facilities relying on real-time data transfer between remote systems and plant control areas, managers and operators cannot afford downtime or errors in information transfer.
Why is operator math necessary? It is needed to evaluate how well a plant is performing, or what the plant is capable of treating adequately. State authorities consider the topic important enough to include at least a little math on even the lowest level certification exams.
