Questions about Seaham Urban District Council SSO

Who operates Seaham Urban District Council SSO?
Northumbrian Water is the operator named in the annual record. The permit reference is 255/E/0645.
Where does Seaham Urban District Council SSO discharge?
The source names Seaton Burn as the receiving water. This does not show how far a discharge travelled.
How many times did Seaham Urban District Council SSO spill in 2025?
The 2025 return records 10 counted spill events and 1.3 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.
Can I trust the 2025 figures for this outlet?
The monitor worked for 99.7% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Seaham Urban District Council SSO discharging right now?
This record is not matched to a company live feed, so we cannot show a current report. Only the annual figures are available for this outlet.
How accurate is the map marker?
The marker comes from the grid reference in the official annual return, which is accurate to about 1 metres. It shows the recorded outlet position, not the extent of any discharge.
What kind of outlet is Seaham Urban District Council SSO?
The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
How does Seaham Urban District Council SSO compare with other overflows?
Seaham Urban District Council SSO recorded 10 spills in 2025. That is more than 47% of the 14,239 overflows in England with a reported figure, and ranks 7,195th nationally. Among Northumbrian Water overflows it ranks 785th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Tyne and Wear waterbody it ranks 19th of 55. Ranks compare counted spill events only. They do not compare volume or harm.

No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
