Building a safety culture in a water and wastewater utility
A safe water or wastewater utility depends on more than written procedures, required personal protective equipment, and annual training. It depends on daily decisions made in treatment plants, laboratories, lift stations, collection systems, maintenance shops, and control rooms. When employees recognize hazards, communicate openly, and have the authority to stop unsafe work, safety becomes part of how the organization operates.
A strong safety culture protects employees, contractors, visitors, and the surrounding community. It also supports reliable service. Preventing chemical releases, confined-space incidents, electrical injuries, vehicle collisions, and biological exposures reduces disruptions that can affect regulatory compliance and public health.
Utilities across the greater Los Angeles area face varied operating conditions, from aging infrastructure and high-traffic facilities to extreme weather and complex treatment processes. A practical approach must connect worker safety, process safety, emergency readiness, and professional development.
Define what safety means in daily work
Leadership should begin by describing safety in specific, observable terms. Employees need to know that safety includes hazard identification, infection control, chemical handling, ergonomics, traffic management, emergency response, and protection from process upsets. A broad statement such as “work safely” is less useful than clear expectations for a confined-space entry, a chlorine delivery, or a repair near energized equipment.
The definition should also include psychological safety. Operators and maintenance personnel must be able to report near misses, equipment defects, fatigue, and unclear instructions without fear of punishment. A person who raises a concern is providing valuable operational information. Treating that report as a contribution encourages early intervention, when corrective action is less costly and less disruptive.
Use toolbox talks, shift meetings, onboarding sessions, and supervisor observations to reinforce these expectations. Keep the discussion connected to current work. A short conversation about changing weather, a blocked access route, or an unusual pump vibration can be more effective than a generic presentation disconnected from the day’s tasks.
Make leadership visible and accountable
Managers shape workplace behavior through the resources they approve and the actions they take. If production targets routinely override lockout/tagout, respiratory protection, or permit requirements, employees will understand that safety is secondary. Leaders must schedule work realistically, provide functioning equipment, and address unsafe conditions even when doing so affects short-term performance.
Supervisors should regularly visit field locations and treatment areas, listen to employees, and follow up on reported hazards. Their role is not simply to identify rule violations. It is to learn why a procedure is difficult to follow. An awkward valve location, missing lifting aid, poor lighting, or confusing alarm may reveal a design or planning issue rather than an individual failure.
Accountability should be fair and consistent. Deliberate disregard for a known safety requirement may require discipline, while an honest mistake or a near miss should prompt coaching and system improvement. Track corrective actions to completion, assign clear owners, and review overdue items at management meetings. What leaders measure and revisit becomes part of the utility’s operating culture.
Control hazards before relying on behavior
The hierarchy of controls provides a practical framework for reducing risk. Start by eliminating the task or hazard when possible. Then consider substitution, engineering controls, administrative controls, and personal protective equipment. For example, remote sampling, fixed gas detection, machine guarding, ventilation, and safer chemical delivery systems can reduce exposure more reliably than reminders to wear protective equipment.
Job hazard analyses should be concise and task-specific. Before beginning work, employees can identify the energy sources, chemicals, biological agents, traffic risks, fall hazards, atmospheric conditions, and potential changes in the process. The analysis should explain controls, responsibilities, communication methods, and emergency actions. Review it whenever conditions change rather than treating it as a form completed once.
Process control also has a safety dimension. An incorrect setpoint, misunderstood trend, or delayed alarm can create dangerous conditions for both employees and the environment. The “tears and beer” analogy offers a memorable way to discuss process behavior, quality impacts, and the consequences of poor control decisions with operations teams.
Turn training into demonstrated competence
Training should reflect the work employees actually perform. A new operator may need instruction in chemical safety, confined spaces, fall protection, personal protective equipment, emergency procedures, and safe sampling. Experienced employees may need refresher training when equipment changes, an incident occurs, or a procedure is revised.
Competence is demonstrated through practice, observation, and conversation. Have employees explain the steps of an energy-control procedure, conduct a pre-entry briefing, inspect a harness, or respond to a simulated alarm. Supervisors can document proficiency while identifying areas that need additional coaching. This approach is stronger than relying on attendance records alone.
Professional development can support a deeper safety mindset because technical knowledge improves judgment. Resources such as operator exam preparation help staff build the process knowledge needed to recognize abnormal conditions and make sound decisions under pressure. Utilities can also partner with professional organizations for workshops, facility tours, and targeted training in operations, automation, and maintenance.
| Safety culture element | Practical utility action | Evidence of progress |
|---|---|---|
| Leadership commitment | Include safety goals in operating plans and supervisor evaluations | Resources approved and actions completed |
| Employee participation | Invite operators and maintenance staff to review procedures and hazards | More useful reports and higher meeting participation |
| Hazard control | Apply engineering solutions before relying on PPE | Reduced exposure and fewer repeat findings |
| Training and competence | Use demonstrations, drills, and field observations | Employees perform critical tasks consistently |
| Learning from events | Review near misses without blame and share lessons | Corrective actions address root causes |
| Emergency readiness | Practice realistic scenarios involving chemicals, power, and confined spaces | Faster, clearer responses during drills |
Build a reporting and learning system
A useful reporting program makes it easy to document near misses, unsafe conditions, equipment defects, and positive safety observations. Employees should be able to report through a mobile form, paper card, supervisor, or control-room process. Multiple channels matter because field conditions and comfort levels vary across the workforce.
The response is more important than the form. Acknowledge reports promptly, communicate the immediate control, and explain what will happen next. When employees see that a damaged ladder is replaced, a traffic pattern is changed, or a recurring alarm is investigated, confidence in the system grows. If a report cannot be resolved quickly, provide a status update rather than allowing it to disappear.
Review incidents for contributing conditions, including staffing, workload, communication, design, training, procurement, and maintenance. Share lessons across shifts and facilities. The 2024 LABS operations seminar highlighted the value of exchanging practical experience among water professionals, and utilities can use seminar takeaways to strengthen discussions about operational reliability and risk awareness.
Make participation part of the operating rhythm
Safety improves when employees have defined opportunities to influence decisions. Include operators in procedure reviews, capital project planning, equipment selection, incident investigations, and emergency exercises. Their experience can identify access problems, maintenance conflicts, and workarounds that may be invisible in design documents.
Useful practices include:
- Hold brief, focused safety discussions at the start of high-risk work.
- Review one near miss, hazard observation, or corrective action during regular staff meetings.
- Invite employees to test revised procedures before formal approval.
- Recognize constructive reporting and safe problem-solving, not just injury-free days.
- Coordinate contractor orientation, permits, and field oversight before work begins.
Recognition should reinforce the behaviors the utility wants to see. Thank employees for stopping a job, improving a procedure, reporting a close call, or helping a coworker understand a hazard. Avoid incentives that discourage reporting by making low incident counts the sole measure of success. A quiet record may indicate underreporting rather than excellent control.
Keep safety resilient through change
Utilities experience retirements, staffing changes, new regulations, automation projects, construction, emergency repairs, and severe weather. Each transition can introduce unfamiliar hazards. Management of change should therefore address staffing, procedures, alarms, cybersecurity, chemical systems, access, training, and emergency response before a modification goes live.
A resilient program also protects workers from fatigue and rushed decision-making. Shift schedules, overtime, callouts, heat exposure, and emotionally difficult incidents can affect attention and judgment. Supervisors should plan adequate staffing, provide recovery time where possible, and encourage employees to report when fatigue creates a meaningful risk.
A safety culture is built through repeated actions: visible leadership, reliable controls, useful training, respectful reporting, and consistent follow-through. LABS of CWEA gives water and wastewater professionals opportunities to learn from peers and strengthen technical practice across the Los Angeles Basin. Bring these principles into the next staff meeting, job hazard review, or facility improvement project, and turn each conversation into a safer way to serve the community.
