Water and wastewater utilities face a demanding assignment: maintain reliable service, protect public health and manage infrastructure while balancing limited budgets and staffing. Automation and control solutions are helping them meet those challenges by turning operational data into timely, practical action.
The direction is clear. Utilities are connecting equipment, improving visibility and using more sophisticated controls to respond to changing conditions. According to the National Institute of Standards and Technology, many water and wastewater organizations are adopting automation to improve utility management, operations and service delivery.
Connecting the Dots Across the System
One significant trend is the integration of sensors, telemetry and Supervisory Control and Data Acquisition, or SCADA. Instead of relying solely on periodic site visits, operators can receive current information from tanks, lift stations and treatment equipment.
The EPA explains that intelligent water systems can begin simply by connecting existing sensors and meters and transmitting their data. This approach makes modernization possible in stages, helping communities build capabilities around their most pressing needs. Remote visibility also reduces time spent collecting routine measurements, allowing staff to concentrate on maintenance and problem-solving.
Moving From Monitoring to Responsive Control
Knowing what is happening is valuable. Adjusting operations promptly adds another layer of protection.
Real-time controls use incoming measurements to operate pumps, valves and other equipment within established parameters. In wastewater collection systems, these tools can help manage changing flows and make better use of available storage during wet weather.
The EPA describes systems that combine sensors, analytical software and automated controls to manage wastewater volumes and route excess flow toward storage or treatment. These capabilities give utilities more options for responding to storms and reducing overflow risks.
Putting Energy Efficiency Into Everyday Operations
Another important direction is tighter control of energy-intensive processes. Equipment operating continuously can consume considerable electricity, particularly when output exceeds actual process needs.
The Department of Energy identifies dissolved oxygen and ammonia sensors, advanced aeration controls and variable frequency drives for pumps among established efficiency measures. These technologies help match equipment operation to treatment requirements. The opportunity is practical: reduce unnecessary energy use while maintaining the conditions needed for reliable treatment. Results depend on facility design, equipment condition and operating practices.
Using Analytics to Look Ahead
Utilities are also building toward more proactive decision-making. Historical and real-time data can help teams recognize patterns, assess system performance and prioritize attention.
The EPA notes that artificial intelligence and machine learning can build on connected infrastructure to evaluate historical information, provide predictive capabilities and support proactive planning. These tools offer decision support, but their usefulness depends on trustworthy measurements and knowledgeable operators who can evaluate recommendations.
Making Secure Access Part of Modernization
As systems become more connected, cybersecurity must be built into their operation. Secure remote access is receiving particular attention.
In June 2026, NIST released guidance demonstrating remote access architectures for water and wastewater operational technology using commercially available solutions. The guidance addresses organizations with different sizes and resources, reinforcing that security belongs in modernization planning from the beginning.
For communities, the best investment starts with a defined operational problem and a measurable goal. Skilled professionals remain essential to selecting, maintaining and supervising these solutions. With that foundation, automation can help utilities respond faster, use resources more effectively and deliver dependable service.
