Water loss from undetected leaks in municipal distribution networks costs governments billions every year — yet most utilities still rely on customer complaints and annual pressure surveys to find problems. The US alone loses an estimated 2.1 trillion gallons of treated water annually through distribution leaks, representing both a financial drain and a public health risk. For water utility managers, the question is no longer whether to modernize leak detection but how to connect detection data to repair execution in a way that actually closes work orders on time and documents every action for regulatory reporting. OxMaint gives water utilities a single platform where sensor alerts trigger work orders, repair teams get mobile-dispatched instructions, and every intervention is logged against the asset record.

The Water Utility Leak Detection Gap
Most municipal water systems were designed and built 40–80 years ago. Cast iron and ductile iron mains degrade predictably, but the maintenance systems used to track their condition have not kept pace with the infrastructure they monitor. The gap between when a leak starts and when a repair crew is dispatched is where utility budgets disappear and public health risks accumulate.

Detection Technologies OxMaint Integrates With
OxMaint does not manufacture sensors — it connects to the detection technology your utility already uses or selects, and turns sensor data into actionable maintenance records.

Repair Management: From Detection to Documented Closure
Detection is only half the problem. Municipal water utilities often have excellent leak detection equipment but no structured workflow to move from alert to dispatched crew to closed work order with full documentation. OxMaint provides the repair management layer that detection systems lack.
1
Alert Received & Asset Identified
Sensor alert is matched to the specific main segment, hydrant zone, or pressure district in OxMaint's asset registry. Asset history, material type, age, and prior repair records are immediately available to the dispatcher.
2
Priority Classified & Crew Assigned
OxMaint classifies leak priority based on alert severity, asset criticality, and proximity to sensitive customers (hospitals, schools, fire stations). The right crew — in-house or contracted — is assigned via mobile notification with full work package details.
3
Field Execution on Mobile
Field crews receive job details, isolation valve locations, repair specifications, and safety requirements on their mobile devices. Progress updates, photo attachments, and material usage are logged in real time against the work order.
4
Post-Repair Verification
After repair, sensor readings in the affected zone are automatically compared to pre-leak baseline to confirm resolution. If pressure or flow anomalies persist, the work order is flagged for follow-up rather than incorrectly closed.
5
Regulatory & Asset Record Update
The closed work order updates the main segment's maintenance history, triggers any required regulatory notification, and feeds the asset's condition score used to prioritize future capital rehabilitation. Every leak event is documented for state utility commission reporting.

Water loss management has entered a new era. The utilities that are hitting 8–10% non-revenue water targets are not the ones with the best leak detection sensors — they are the ones that have closed the loop between detection and repair management. A sensor that alerts to a leak and triggers a paper work order is only marginally better than no sensor at all. The gains come from a fully connected workflow where detection, dispatch, execution, and documentation happen in one system with real-time visibility at every step.

Frequently Asked Questions
Does OxMaint replace our existing SCADA or leak detection system, or work alongside it?
OxMaint works alongside your existing SCADA and detection infrastructure — it does not replace it. OxMaint receives alert data from your detection system via API, Modbus, or webhook integration, and handles the repair management workflow from that point forward. Your field team gets dispatched work orders on mobile, repair actions are logged, and documentation is generated automatically. The detection system keeps doing detection; OxMaint handles everything from alert to closed record.

How does OxMaint help with state and federal water utility reporting requirements?
OxMaint automatically generates audit-ready documentation for every leak event — including detection timestamp, work order creation, crew dispatch, repair actions taken, materials used, and post-repair verification. These records satisfy most state Public Utilities Commission reporting requirements and support EPA annual water audit submissions. OxMaint includes report templates pre-configured for common regulatory formats, and data exports are available in formats compatible with major regulatory reporting platforms. The compliance module is part of every OxMaint subscription.

Can OxMaint help prioritize which mains to rehabilitate based on leak history?
Yes. OxMaint builds a maintenance history for every main segment in your asset registry. As leak events, repair records, pipe age, material type, and soil condition data accumulate, OxMaint's analytics module generates an asset condition score that can be used to rank rehabilitation candidates. This data directly supports capital improvement plan (CIP) development and can be exported to support grant applications for infrastructure funding. Utilities using this approach report significantly better alignment between their repair spending and actual infrastructure risk profiles compared to age-only prioritization methods.
