The outside view

The national voice of public wastewater and stormwater agencies for fifty years, uniting utilities of every size to shape clean water law, regulation and litigation, and to prove they are trustworthy stewards of public health.

  • Consensus
  • Build
  • Inward
  • Operational

Their shape

The League

Far-flung, and stronger for it.

The League is a federation of many, where the value lives in the connections between its members and chapters. Its gift is reach and resilience, its challenge is holding a shared identity across all its parts.

Also reads toward The Frontier and The Citadel.

Strengths

→Coordinated scale that punches above its weight.
→Ambition matched by professional execution.
→A credible, unified voice for many.
