Root Cause Analysis for Water and Wastewater Failures

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 structured failure investigation using fault tree and 5-Why methodologies 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 structured failure investigation using fault tree and 5-Why methodologies 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.
