Wastewater outlets

Outfall: a pipe or outlet where wastewater enters a water body.

None in EPA or state outlet records; 1 place named in its own overflow reports (provisional locations).

Places named in overflow reports (provisional)

1 place · 1 not on the map (reports say the sewage reached no water)

Provisional location from overflow reports. Where the operator's own reports put an overflow: a manhole, pump station or plant. Not an outfall listed in a permit.

  • Reported place · 1 overflow report, latest Sep 1, 2026 · confidence medium · no water record yet · not on the map: its reports say the sewage did not reach a water

Source: the operator's own overflow reports to the state. DirtyWaterWatch groups reports within 50 metres into one place and finds the water below it with U.S. Geological Survey river maps (NLDI, NHDPlus). Not a permitted outfall; provisional until an official outfall record exists.

Reports and advisories

Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater.

How these charts are counted

We count each discharge once. Where a source publishes notices and confirmed reports, we use confirmed reports for an operator's month when available; otherwise we use notices. We combine revisions and exclude duplicate state reports copied by the U.S. Environmental Protection Agency (EPA). Monthly and yearly totals appear separately. Status hours follow this site's rules. Shaded gaps mean missing coverage, not zero discharges.
