Reported sewage discharges in Washington

Updated Nov 6, 2026, 3:10 AM EST. We track 135 waters in Washington: 1 with a sewage discharge status, 18 with caution after a discharge, and 0 with no confirmed discharge end. 116 have no current status on their water outline. 11 discharge records dated within the last 30 days.

The law and practice: Washington law sets no period after a sewage spill during which the water is to be avoided. The rule this site applies, with its source

Data and its limits

Dated reports Washington publishes dated overflow reports; the newest is from Nov 5, 2026.

What the law requires. RCW 90.48.636, enacted in 2025, requires the Department of Ecology to publish online, from July 1, 2026, every sewage spill reported to it under an individual water quality permit, combined sewer overflows included, with the estimated volume, level of treatment, when and where it began, when it ended once known, the area potentially affected and the steps taken to contain it, and to add the final information within a reasonable time after the spill ends. Operators report their spills to Ecology under their permits. The law sets no posting deadline; Ecology aims to post within five working days of the operator's report. No period after a spill is set during which the water should be avoided. Combined sewer operators (sewage and rainwater in one pipe) also owe the public notice under their permits: King County and Seattle publish a status map of their outfalls, post signs at them and advise staying out of the water near one for 48 hours after it overflows.

What is published. Ecology's list, from June 2026, gives the facility, start and end to the minute, volume, treatment level, a street block or intersection and the area potentially affected: 72 reports on November 4, 2026, most of them sewer overflows. King County's map shows every 10 minutes whether each of 125 combined sewer outfalls in Seattle is overflowing, overflowed in the last 48 hours, has had no recent overflow or has no data; the county notes the data has not been reviewed for accuracy.

What is not published. Ecology's list has no status, map point, permit number or posting time, and names a water only when the operator's description does (18 of the 72). King County's map gives no times, volume or water, and keeps no history. Spills not reported under an individual permit, such as a private line's backup, are not listed.

Known problems in the data. Several reports give an end before the start, and volumes are free text, sometimes ranges or rates.

What this site does about it. A report with an end is shown to its end, then with this site's caution (72 hours; 96 on lakes, ponds and reservoirs), since the law sets no period. Because Ecology's list states no status and fills in an end once known, a report without one is not taken to be still running: caution for 14 days from its start, then hatched "End not confirmed" until 30 days after it began. An end before the start is kept as published but not used. The county's map is read hourly: an overflow is dated to the readings that first and last showed it, then the operators' own 48 hours apply, quoted as theirs. On Puget Sound a discharge colours a modeled stretch of shore water up to 20 kilometres each way from the outfall, never the whole sound; other bays, sounds and inlets are not coloured whole, and a report on one is listed on that water's page. The operators' descriptions of the steps taken to contain a spill are not reproduced, since they can name the people involved and residents' homes; Ecology's list links each full report.

As of November 6, 2026, of the 744 registered treatment-plant and sewer outfalls in Washington (closed outfalls aside), 653 (88 percent) are tied to a water record on this site and 91 (12 percent) are not yet (the water they discharge to has no record, or the location given could not be matched); an overflow at one of those appears on the map at its point with no water coloured.

Of this state's reports on this site, 100 percent are dated to the day or better; the newest dated report is from Nov 5, 2026. Coverage: Dated reports.

What stands in the way

With no deadline, a report can appear days after a spill, and the bill's e-mail alerts were cut before it passed. Spokane's real-time combined sewer page refuses automated reading, so Spokane's overflows are seen here only when reported to Ecology. Ecology's terms allow use of its data with credit and a link to Ecology, which this site gives, and bar any use in a political campaign or lobbying effort.

100 percent of the sewer operators here have each overflow posted on the web, by the operator or the state (219 of 220).

How each state reports

Map sources: water outlines and launches from OpenBoatLaunch and OpenStreetMap contributors (Open Database License); wastewater outlets from EPA and state records; downstream estimates by DirtyWaterWatch using U.S. Geological Survey maps and flow data. Base map: OpenFreeMap and OpenMapTiles.

Zoom in to see the wastewater outlets: solid dots are combined sewer outfalls, ringed dots treatment plant outfalls, small hollow diamonds places named in overflow reports (provisional) and grey dots closed outfalls. A yellow ring with a dashed edge means discharge likely or possible: heavy rain, no report received.

What this page covers

Post-discharge periods and their sources

No period: a water is red only while the discharge is reported ongoing. The Department of Ecology must post on a public website each sewage spill reported to it under an individual water quality permit, with the estimated volume, the level of treatment, when it began, where, when it ended once known and the area potentially affected, and add the final information within a reasonable time after the spill ends (RCW 90.48.636); the law sets no posting deadline, and Ecology aims to post within five working days of the operator's report. Operators report spills to Ecology under their permits. King County and Seattle advise staying out of the water near a combined sewer outfall for 48 hours after it overflows; that window is used for the overflows their status map reports. This site marks a reported discharge while it runs and applies its own caution after it ends

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.
