Combined sewer overflow (CSO): sewage mixed with rainwater spills from a shared sewer system. Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater. Treatment bypass: wastewater skips one or more treatment steps. Blended discharge: wastewater that skipped some treatment is mixed with treated wastewater. Outfall: a pipe or outlet where wastewater enters a water body.

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.

  • U.S. Environmental Protection Agency sewer overflow records: records from May 3, 2022 to the latest update (limited records)
  • ny-dec-sprtk: records from August 11, 2021 to the latest update

Wastewater outlets on this water

Treatment plant outfalls

2 outfalls

Source: U.S. Environmental Protection Agency (EPA) permit records (ICIS-NPDES permitted features): where a treatment plant’s permitted discharge leaves. No national source says whether a plant outfall is open or closed.

Places named in overflow reports (provisional)

1 place

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.

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.

Sewer operators listed for this water: STOCKPORT- T KINGS ACRES STP, Valatie (V) STP.
