Treatment technologies are only as effective as the employees available to run them
Small utilities do not typically fail to comply with regulations because treatment technology alone falls short. Instead, they lose compliance when staffing gaps leave too few people to run the system well, respond quickly, and keep up with routine obligations. Across the United States, small systems make up most community water systems, and many already operate with limited staff, thin budgets, and almost no redundancy.
Utilities need the technical, managerial, and financial capacity to maintain system stability over time. That capacity depends heavily on having enough trained operators in place. Someone still has to answer alarms, adjust processes, coordinate sampling, manage reporting, and make sound decisions when conditions change. A plant may have enough treatment capacity on paper, but if it lacks operational depth, that design strength can unravel quickly.
The Aging Operator Workforce
Staffing pressure mounts every year. Nearly 90% of the water workforce is 45 or older, and 30% will likely retire within the next decade. At the industry level, utilities continue to rank workforce challenges among their top concerns as retirements accelerate, recruiting remains difficult, and utilities compete for specialized talent.
Small systems feel that strain first and hardest. In many cases, the same people handle operations and maintenance, sampling, management, and customer service. That means one retirement, one resignation, one illness, or one family emergency can throw the whole operation off balance.
Replacing lost capacity is rarely simple. Water and wastewater plants run around the clock, operators stay on call for emergencies, and new hires may need substantial on-the-job training before they can work independently. Utilities don’t just need headcount — they need judgment, certification, plant familiarity, and the confidence to act under pressure.
When a Vacancy Turns Into Regulatory Exposure
In a large utility, staffing shortages are easier to cover. In a small system, one vacancy can become a defining operational risk. Research has found a relationship between workforce quality and Safe Drinking Water Act compliance, so in smaller utilities, even one highly qualified operator can strongly influence outcomes.
That is why staffing risk belongs in the compliance conversation, not off to the side as a separate HR problem. When a system concentrates process knowledge in one or two people, ordinary disruptions may carry regulatory consequences. Preventive maintenance is deferred. Process adjustments slow down. Sampling and documentation become harder to keep on schedule. Oversight narrows at exactly the moment a utility needs more of it.
The EPA’s own resources link utility workforce development to greater capacity and improved regulatory compliance. Technology still matters, of course, but without enough good operators, even good infrastructure can drift into trouble.
Storms Expose the Weak Spots
Storms and emergencies make vulnerabilities impossible to ignore. Emergency response planning doesn’t only consider backup power, flooding, or chemical supplies. It also requires clear personnel roles, defined responsibilities, and a plan for recalling staff during an incident. If a utility lacks coverage by skilled workers, a response plan may appear complete on paper yet remain fragile in the field.
That’s one reason mutual aid matters so much. Utilities often rely on external support to quickly share personnel, equipment, and other resources, especially when local teams are already stretched thin. Those networks provide real value, but they also underscore the core issue: many small systems simply do not have enough internal redundancy to absorb a disruption on their own. While mutual aid can support emergency response, it does not replace the need for consistent, day-to-day operational coverage.
Structural Ways to Reduce Staffing Risk
Managed operations and maintenance (O&M) can reduce dependence on one or two local individuals by broadening the operating bench, standardizing procedures, and bringing in deeper process expertise before a problem becomes a violation. Regional support models can help in much the same way through shared operators, shared management, or shared operational services across systems.
Different communities will need different versions of that support. Some may benefit from formal partnerships. Others may need contracted operations support or a broader service arrangement that reduces single-point dependence. The model can vary, but the objective doesn’t: Build enough operational resilience that compliance doesn’t hinge on one person always being available.
Capacity Is Human as Well as Mechanical
At Seven Seas Water Group, our service model matters just as much as process design. Water-as-a-Service® gives communities a long-term, performance-based way to secure infrastructure and operations, with Seven Seas accountable for performance over the life of the agreement. For communities that want to keep options open, a timeline-based lease with Seven Seas O&M can deliver a similar full-service experience.
Seven Seas supports more than 220 operating plants, achieving a consistent average plant availability of 98.7%. Sustainable compliance depends on the people behind the equipment as much as the equipment itself. When communities prefer local involvement, we proudly hire and train operators from the surrounding area, investing in the local workforce while building stronger, more resilient operations. If staffing gaps are starting to affect operations or compliance, connect with our team to explore practical ways to strengthen system resilience.
