US municipal water utilities lose an estimated $2.6 billion annually to unplanned pump failures, aging distribution infrastructure, and reactive maintenance cycles that cost 3 to 5 times more than planned interventions. When a mid-sized municipal water authority managing 14 pump stations, two water treatment plants, and 380 miles of distribution main found its emergency repair ratio climbing to 51% of total maintenance spend, leadership faced a choice between capital replacement and operational reform. Book a demo to see how Oxmaint delivers predictive pump monitoring and SCADA-integrated compliance documentation for municipal water operations.
Case Summary
A municipal water authority serving 87,000 residents deployed Oxmaint with SCADA integration across 14 lift stations and two water treatment plants to shift from a reactive maintenance model to predictive pump monitoring and automated compliance scheduling. Within 12 months, equipment downtime fell 40%, EPA Safe Drinking Water Act compliance violations dropped 70%, emergency repair spend declined from 51% to 22% of total maintenance budget, and the authority passed its first State Revolving Fund inspection with zero findings — unlocking $3.8M in low-interest infrastructure financing.

Background: A Water Authority Operating at Reactive Maintenance Limits
The authority's maintenance program had operated without a structured CMMS for over a decade. PM scheduling was managed through paper logbooks at each pump station and a shared spreadsheet updated by the maintenance supervisor. Inspection records for Safe Drinking Water Act compliance were captured on paper forms and filed in binders at each facility. When state environmental regulators requested documentation of the authority's chlorine residual monitoring and backflow prevention inspection program during a routine compliance review, the compliance officer required 11 days to compile the requested records from 14 separate site files. Book a demo to see how Oxmaint structures a defensible CIP budget justification from real asset condition and maintenance cost data.
01
51% Emergency Repair Ratio Draining Taxpayer Funds
Over half the $4.2M annual budget went to reactive repairs at 3–5x planned cost. Unplanned pump failures averaged $87,000 per event — with no structured PM program to reverse the trend.
02
No SCADA-to-Work-Order Integration at Lift Stations
SCADA alarms at 9 of 14 stations were monitored but never converted to work orders. Alarm-to-response averaged 4.2 hours. Four pump failures that year had generated recurring alarms for weeks before failing.
03
Paper-Based Compliance Records Creating Regulatory Risk
Paper records across 14 sites required 11 staff-days to compile for state review. Three EPA documentation findings in the prior year resulted in a formal notice of violation and $18,500 in penalties.
04
Disconnected CIP Justification With No Asset Condition Data
CIP requests were built on age estimates, not condition data. City council cut two consecutive submissions for lack of evidence — blocking the $6.8M pump replacement program the authority needed.
Why Oxmaint Was Selected Over Competing CMMS Platforms
The authority evaluated four CMMS platforms over a 90-day procurement process. The evaluation committee included the Director of Public Works, the Water Operations Manager, the Compliance Officer, and the IT Director. The three primary selection criteria were: native SCADA alarm-to-work-order conversion without custom middleware, EPA and Safe Drinking Water Act compliance documentation built into the PM workflow rather than as a separate module, and deployment timeline short enough to produce compliance documentation improvements before the next state regulatory review cycle.
Native SCADA Alarm-to-Work-Order Conversion
Connects to existing pump station SCADA via OPC-UA and Modbus. Alarm thresholds map directly to PM work order triggers — no custom middleware, no configuration sprints after deployment.
EPA Compliance Documentation in PM Workflow
Safe Drinking Water Act templates, chlorine residual logs, and backflow prevention records are embedded in the PM workflow. Every completed task auto-generates a timestamped, operator-attributed compliance record.
Asset Condition Registry With RUL Engine
Full FCI scoring and Remaining Useful Life calculation for pumps, valves, clarifiers, and distribution mains — producing condition-based CIP evidence that city councils approve, not age-estimate guesswork.
8-Week Deployment Before Next Compliance Review
With a state review 4 months out, all 14 pump stations and both treatment plants were deployed in 8 weeks via mobile QR scanning — no lengthy enterprise IT implementation required.
Implementation: Eight Weeks Across 14 Pump Stations and Two Treatment Plants
Deployment was structured in four phases, prioritizing SCADA integration and compliance documentation capability first. The authority's operations were unionized, and the implementation team followed Oxmaint's phased rollout protocol — introducing mobile field tools to crews in training sessions before go-live rather than changing work assignment procedures unilaterally. All PM assignments and work order closures continued through existing supervisor-crew reporting protocols during the transition period.

Frequently Asked Questions
QHow does Oxmaint integrate with an existing SCADA system at a pump station without replacing the SCADA hardware?
QWhat documentation does Oxmaint produce for EPA Safe Drinking Water Act compliance inspections?
QHow long does deployment take for a water utility with multiple pump stations and treatment plants across different sites?
Deployment for a water utility of this scale — 14 pump stations and 2 treatment plants — took 8 weeks from start to full operational status, including SCADA integration and EPA compliance template configuration. Asset registration uses mobile QR scanning, which eliminates the manual data entry phase that extends enterprise system deployments. Most water utilities of comparable scale are fully operational within 6 to 10 weeks.
QAs a Water Authority Director presenting to city council, how do I justify the CMMS investment when the capital budget is already under pressure?
The financial case is straightforward: a water utility spending 51% of its maintenance budget on reactive repairs is spending 3 to 5 times more per repair event than planned maintenance costs. Shifting that ratio by even 15 percentage points on a $4.2M maintenance budget produces over $1M in annual savings — exceeding the CMMS cost in year one. Oxmaint's CIP forecasting dashboard also produces the evidence-based condition data that council members require before approving capital line items.

QDoes the same Oxmaint platform work across public works, parks, and fleet departments in addition to water utilities?
Yes. Oxmaint is built for multi-department government operations — water, public works, parks, fleet, and facilities can all operate from the same platform with role-based access controls for each department. Asset hierarchies mirror government org structures, and departmental KPI dashboards are independent while consolidating at the city or county portfolio level. This is a meaningful operational advantage for water main breaks that affect public works and parks simultaneously.
QCan Oxmaint produce the asset condition documentation required for a State Revolving Fund infrastructure financing application?
Yes. State Revolving Fund applications require documented asset condition assessments and evidence of structured maintenance programs as eligibility criteria. Oxmaint's FCI scoring, RUL projections, and PM compliance history reports satisfy the asset documentation requirements for SRF applications in most states. The water authority in this case study had its $3.8M SRF application approved following the first clean regulatory inspection after deployment.
