Overview
Stop Overpaying on Your Water & Sewer Bills
Water and sewer bills from utilities across the U.S., city departments, water districts, and private providers often contain errors that cost customers real money. Overcharges add up quickly, and many organizations don’t realize they’re entitled to rate corrections, credits, or refunds. Simply paying the bill and assuming it’s right can be expensive.
National Auditing Services & Consulting (NASC) performs comprehensive water/sewer audits nationwide for multifamily, commercial, industrial, institutional, and municipal customers.
Common issues we uncover:
- Misapplied rates or incorrect service classes
- Estimated reads and overlapping billing periods
- Broken or undersized/oversized meters and wrong multipliers
- Sewer charges billed on water used for irrigation, process, or evaporation
- Leak adjustments not applied or calculated incorrectly
Service Benefits:
