Wastewater treatment plant map

Press "Plants near me" and allow location access; the map zooms to your area and lists the ten nearest publicly owned plants with their distance and flow. Without location access, zoom the map or pick your state below.

All 11,783 publicly owned treatment works in the Klarifi directory: municipal and district plants with an NPDES discharge permit and either reported flow or treatment structures identified from aerial imagery. Industrial dischargers are not shown here.

Coordinates come from the EPA Facility Registry Service and are checked against aerial imagery by Klarifi, so the dot sits on the plant rather than on the town hall.
