"The fragility of aging #WaterInfrastructure is evident in many communities. The American Society of Civil Engineers' U.S. Infrastructure Report Card in 2021 gave U.S. municipal #water systems overall a grade of C-minus.

Flood protection infrastructure earned even lower grades: U.S. #levees and #dams both received D grades.

The challenges:
1: Many stakeholders; who decides?
2: Past decisions affect future choices
3: Who pays?"
