Why Water Utilities Need Better Asset History, Not Just More Maintenance Data
By Palak Sheth
Water and wastewater utilities already collect a large amount of operational information. Treatment plant inspections, pump station checks, valve records, hydrant notes, pipe condition assessments, tank inspections, SCADA alarms, maintenance logs, corrective actions, photos, and field observations all provide useful details about system performance.
The challenge is that this information is often reviewed as individual records rather than as part of a long-term asset history.
A single pump inspection may identify a minor issue. A valve may be exercised and recorded. A tank inspection may note coating deterioration. A field crew may document a recurring pipe concern. A corrective action may be assigned and closed. Each record may be accurate, but if the information is not connected across assets, locations, and time, the larger pattern can be difficult to see.
For water utilities, better asset history is not about collecting more data for its own sake. It’s about making existing inspection and maintenance information useful enough to support reliability, maintenance prioritization, capital planning, and long-term service delivery.
Asset Management Depends On Usable History
Water infrastructure is asset-intensive. Utilities are responsible for maintaining pipes, pumps, valves, tanks, treatment equipment, collection systems, distribution systems, controls, and facilities that often operate for decades. The U.S. EPA describes asset management as a process that helps water systems maintain a desired level of service at the lowest lifecycle cost, while supporting long-term sustainability and system capacity.
That goal depends on more than an inventory. Knowing that an asset exists is not the same as knowing how it is performing.
A useful asset history shows what has happened to the asset over time. It connects inspections, observed conditions, maintenance activities, failures, corrective actions, photos, risk notes, and repair decisions. This helps teams understand whether an issue is new, recurring, worsening, or tied to previous work.
Without that history, utilities may have data but still lack operational context. A pump may appear to need another repair, when the deeper issue is repeated service under the same operating condition. A valve may be listed as maintained, but prior inspection notes may show that it has become increasingly difficult to operate. A tank may pass inspection, while earlier records show a pattern of coating concerns that should influence future planning.
Asset history gives maintenance and operations teams a clearer view of what the asset has been telling them over time.
Recurring Issues Often Look Routine
Utilities are used to responding quickly when problems appear. A pump alarm is investigated. A valve is repaired. A lift station issue is resolved. A collection system blockage is cleared. A treatment process component is adjusted. The immediate problem is handled, the task is closed and the team moves on.
That responsiveness is necessary, but it can also make recurring issues harder to see.
A single pump seal issue may not seem significant. If the same pump shows repeated findings, the cause may involve operating conditions, installation, suction conditions, vibration, maintenance frequency, or process changes. A single sewer blockage may be cleared quickly. Repeated blockages in the same area may point to grease, roots, pipe condition, slope, infiltration, or capacity concerns.
A valve that repeatedly requires follow-up may need more than another work order. It may need a closer look at accessibility, age, corrosion, torque history, or replacement timing.
Recurring issues are costly because they consume time and resources more than once. They can also increase operational risk if the underlying condition is not addressed. When inspection and maintenance records are disconnected, teams may continue correcting symptoms instead of identifying patterns.
Inspection Records Need Asset-Level Context
A completed inspection record proves that a check was performed. It does not always help the next operator, maintenance planner, engineer, or asset manager understand what was found, why it mattered or whether the same condition has appeared before.
A useful inspection record connects the finding to the correct asset, component, location, condition, severity, photo evidence, corrective action, and follow-up result. A note that says “repaired” or “checked” may close a task, but it does not provide much value for future troubleshooting. A stronger record explains what was observed, what action was taken, whether the result was verified and whether further monitoring is needed.
This level of context matters because water and wastewater assets often deteriorate gradually. Corrosion, leakage, vibration, coating failure, mechanical wear, electrical issues, infiltration, sediment buildup, and structural deterioration may begin as small observations. Over time, those observations can affect reliability, safety, compliance, service levels, and capital needs.
The American Water Works Association (AWWA) notes that asset management principles should be embedded into utility decision-making to support long-term, resilient, and cost-effective service. That decision-making is stronger when inspection records are connected to asset history rather than stored as isolated documents.
Digital approaches to inspection data management can help organize inspection findings, asset condition history, photos, corrective actions and reports in a more consistent workflow.
The value is not simply replacing paper with digital forms. The value comes when records can be searched, compared, and reviewed across assets, sites, and time.
Corrective Actions Should Close The Loop
Corrective actions are central to maintenance and reliability, but they are only useful if they show what happened after an issue was identified.
A field finding may be assigned to a crew. A repair may be completed. A contractor may close a task. A maintenance record may be updated. But closure does not always prove that the issue was resolved or prevented from returning.
A stronger corrective-action history helps answer practical questions. Was the repair completed? Was the condition verified afterward? Did the same issue return? Have similar assets shown the same pattern? Was the cause mechanical, environmental, operational, hydraulic, electrical, or procedural?
For wastewater collection systems, EPA’s CMOM framework emphasizes capacity, management, operation, and maintenance practices as part of collection system performance and overflow prevention. That type of management approach depends on reliable records, not just completed tasks.
If the same lift station repeatedly generates inspection findings, the utility may need to review pump performance, wet well condition, controls, inflow and infiltration, cleaning frequency, or operating demand. If repeated valve issues appear in a specific pressure zone, the team may need to review asset age, accessibility, corrosion exposure, or replacement planning.
Closing the task is not the same as closing the loop. Utilities gain more value when corrective actions become part of a long-term history that helps prevent repeat problems.
Better History Supports Capital Planning
Capital planning often depends on understanding risk, condition, criticality, and service impact. However, these decisions are difficult when inspection and maintenance records are incomplete or difficult to compare.
A single inspection result may show the current condition of an asset. A connected history can show whether that condition is stable, deteriorating, or recurring after repair. That makes a difference when deciding whether to repair, rehabilitate, replace, or monitor an asset.
The Water Research Foundation has identified asset management as a major area of research because water services depend on extensive infrastructure while utilities must control cost and reduce risk.
For example, two pumps may have similar age and capacity, but one may have a history of repeated repairs, vibration findings, and corrective actions. Two pipe segments may appear similar in inventory data, but one may have repeated maintenance calls, condition observations or service disruptions. Two tanks may be the same age, but one may show a longer history of coating deterioration or inspection concerns.
Asset history helps utilities move beyond age-based decisions. It supports planning based on condition, recurrence, consequence, and operational evidence.
AI Needs Better Utility Records
Artificial intelligence is increasingly discussed in water and wastewater operations. AI-supported tools may help utilities review large volumes of inspection records, identify recurring issues, compare assets, support maintenance prioritization, and improve planning.
However, AI depends on the quality of the underlying information.
If asset names are inconsistent, inspection notes are vague, photos are not connected to the correct asset, defect categories are unclear, and corrective actions do not show outcomes, advanced analysis will have limited value.
AI can help preventive maintenance programs by analyzing inspection history, asset condition, recurring defects, and corrective-action outcomes to identify risk patterns and support more informed maintenance planning.
For broader AI implementation, the same principle applies. AI is more useful when connected to business workflows, structured data, and specific decision points rather than treated as a standalone tool.
For utilities, better records have immediate value even before advanced analytics are introduced. They improve today’s maintenance decisions and create a stronger foundation for future tools.
Practical Steps For Utilities
Improving asset history does not require a complete system overhaul. Utilities can begin with practical improvements.
First, standardize how findings are recorded. Similar issues should be described in similar language so they can be compared across assets and locations.
Second, connect each finding to the correct asset and component. A pump issue, valve issue, pipe concern, tank finding, or electrical observation should remain tied to the asset involved.
Third, include photo evidence when useful. Photos help future reviewers understand the condition without relying only on short written notes.
Fourth, improve corrective-action closure notes. “Completed” is not enough. The record should explain what was done, whether the result was verified, and whether follow-up is needed.
Fifth, review repeat findings regularly. Operations, maintenance, engineering, and asset management teams should look for issues that continue to appear across inspection cycles, sites, or similar assets.
Finally, use history during planning discussions. Recurring findings can inform preventive maintenance, rehabilitation planning, capital budgeting, contractor follow-up, inspection frequency, and replacement decisions.
From Maintenance Data To Better Asset Decisions
Water and wastewater utilities already collect valuable inspection and maintenance information. The opportunity is to make that information easier to use after the immediate task is closed.
A single inspection record shows what was found during one check. A connected asset history shows whether the condition is new, recurring, worsening, or tied to previous corrective actions.
For utilities, the most useful record is not simply the one that proves an inspection was completed. It is the one that helps the next person understand what happened, what was done, and whether the issue is likely to return.
Better asset history can help utilities reduce repeat problems, improve maintenance planning, support capital decisions, and strengthen long-term reliability across water and wastewater systems.
