Real-time network water quality integrity monitoring software
The distribution system is a critical component of every water utility. Its primary function is to economically provide a safe, reliable water supply at an acceptable level of service, and its failure to do so is a serious system deficiency. Breaches in water quality integrity can lead to serious contamination events and detrimental or fatal water quality episodes. Maintaining the water quality integrity of the distribution system is therefore of paramount importance.
QualWatch, a comprehensive real-time anomaly detection and early warning system, enables water utilities to continuously monitor and assess network water quality dynamics as they occur, helping them identify breaches in water quality integrity and build the resiliency and agility to respond with minimal disruption to protect public health. It also empowers users to foresee and pre-empt future network water quality integrity breaches.
The primary strength of QualWatch is its ability to monitor real-time changes in water quality parameters (e.g., total chlorine, free chlorine, electrical conductivity, pH, total organic carbon, nitrate, chlorophyll, total dissolved solids, turbidity, oxidation-reduction potential and other parameters) and identify potential hazards fast enough to permit effective responses aimed at lessening or avoiding adverse public health and economic impacts. It makes the water quality integrity of the distribution system immediately visible through continuous monitoring and assessment of network water quality dynamics. QualWatch enables water utility operators to compare water quality data against regulatory requirements (e.g., minimum of 0.2 mg/L of free chlorine residual), either confirming normal system performance or identifying changes that fall outside normal water quality variations and the onset of anomalous water quality incidents they can evaluate and act on. The result is proactive network water quality management that ensures safety and security for all consumers.
Most water utilities collect water quality data from online sensors and field devices installed at different network locations and at facilities using a SCADA system, with resulting data stored in a central database. QualWatch can link directly to this central database, analyze and filter the data in real time to eliminate extreme values, and compare data to expected values, recognize abnormal changes and automatically compute the probability of an anomalous water quality event. A water quality event is defined as a potential breach in network water quality integrity (internally or externally derived contamination).
An invaluable water security and contamination warning system, QualWatch provides continuous online monitoring of water supply and distribution networks to detect and monitor contaminants and prevent security breaches. It can analyze standard water quality data (e.g., total chlorine, free chlorine, electrical conductivity, pH, total organic carbon, nitrate, chlorophyll, total dissolved solids, turbidity, oxidation-reduction potential and other parameters) from online water quality sensors and field devices over time, then compare the data with expected values and recognize changes. It can help detect a wide variety of chemical and biological contaminants, including pesticides, metals, and pathogens — ensuring the water infrastructure is fully protected.QualWatch gives water utility owners and operators the unprecedented ability to visualize and assess their network water quality performance in real time and compare current water quality dynamics with anticipated performance — allowing them to manage their water networks in a more effective and highly proactive way. By enabling them to rapidly detect abrupt water quality deviations, this state-of-the-art predictive technology puts them at a tremendous advantage in managing their water supply and distribution systems more efficiently and ensuring regulatory compliance.
Designed for online applications with existing SCADA systems and water quality sensors, QualWatch delivers fundamental advances in how effectively water utilities operators monitor regulatory compliance and the water quality integrity of their networks. By enabling them to take remedial action the moment breaches are detected, quickly mitigating adverse public health and economic impacts, it empowers operators to make better predictions and smarter decisions, and target more effective interventions.Easy to learn and use, QualWatch is available as a stand-alone Windows program that runs on nearly any computer. Unlike complex “software as a service” (SaaS) solutions, it can be up and running in just a few minutes within the controlled security of the utility’s local computer. In addition, it does not require any historical data or secondary data from external sources for comparison purposes. At the same time, QualWatch’s unique integration with network modeling and GIS enables water operators to quickly identify viable solutions (e.g., locate the appropriate valves to close to isolate a contamination event and minimize public exposure) and make decisions on the basis of reliable predictive analytics and system dynamics, not intuition. QualWatch can also directly quantify the correlation between multiple water quality parameters, allowing accurate predictions of water quality values. These critical differences represent fundamental advances in how effectively water utility operators can monitor the water quality integrity of their networks and respond if breaches are detected, providing highly accurate early warning detection capabilities and maintaining the highest level of finished water quality. They also greatly enhance utilities’ ability to prepare for and respond to external contamination and minimize the risk of negative public health outcomes.
