State Wastewater Infrastructure Grades (Quality Rankings)

Blog Options – Finding Key Words

 Most states currently hold D to C‑level wastewater grades, reflecting aging treatment plants, underfunded sewer systems, and rising regulatory demands. ASCE’s national wastewater grade is D+, and state-level grades follow the same pattern.

Below is a clean, state-by-state wastewater quality ranking synthesized from the latest ASCE State Infrastructure Report Cards (2021–2026). These are wastewater-only grades, not overall infrastructure grades.

📉 Why Wastewater Grades Are Low

ASCE highlights several nationwide issues:

• Aging treatment plants (40–50 year design life)

• Sewer overflows still common despite improvements

• Replacement rates dropping (3% → 2%)

• Funding gap: $69B/year in wastewater + stormwater needs (only ~30% funded)

• Emerging contaminants increasing treatment costs
