Predictive Maintenance Programs for Water and Wastewater Facilities

influent loading variability from storm events and I&I means equipment operates across a wide range of conditions; many assets are submerged or in confined spaces. In this environment, equipment failures cause permit exceedances, boil-water advisories, sanitary sewer overflows (SSOs), and consent decree violations. Our condition-based monitoring program implementation program specifically targets raw water intake pumps, aeration blowers, clarifier drives, sludge pumps, UV disinfection systems, and lift station pumps — the assets where early detection has the greatest impact on NPDES permit compliance rate and energy cost per million gallons treated. We also account for variable loading patterns driven by weather events and seasonal demand cycles, adapting our measurement approach to maintain data quality despite these operating conditions.

Yes. Water & Wastewater facilities must comply with EPA Clean Water Act, Safe Drinking Water Act, state NPDES permits, and AWWA standards. Our condition-based monitoring program implementation program generates the condition documentation needed for epa discharge permit compliance documentation; sso reporting and prevention program records. Beyond compliance, the condition data drives measurable improvements in NPDES permit compliance rate and energy cost per million gallons treated by converting unplanned failures into scheduled repairs. Most water & wastewater clients see meaningful reductions in permit exceedances within the first 12 months of program implementation.

Site walk to scope the asset population, criticality scoring against pump cavitation, blower bearing failure, corrosion-driven failures, baseline measurements on the top 30 to 60 assets, then a regular cycle of monthly to quarterly cadence per asset criticality. Findings get written up against ISO 17359 (general condition monitoring). For Water & Wastewater facilities, the engagement usually includes coordination with the plant's existing compliance program — pulling Predictive Maintenance results into the EPA NPDES, Safe Drinking Water Act, state DEP audit file. Initial scope runs $15K-$45K depending on asset count, then ongoing at $200-$320 per asset per month.

Sub-sectors with the highest equipment criticality and longest production runs. Within Water & Wastewater, that's typically operations running large rotating equipment 24/7 on tight production schedules. Smaller Water & Wastewater operations with mostly batch work and shorter equipment populations get less leverage from Predictive Maintenance and may be better served by basic preventive maintenance with on-call diagnostic support.
