Questions about North Seaton Level Crossing CSO

Who operates North Seaton Level Crossing CSO?
Northumbrian Water is the operator named in the annual record. The permit reference is 225/1020.
Where does North Seaton Level Crossing CSO discharge?
The source names River Wansbeck(SALINE Estuary) as the receiving water. This does not show how far a discharge travelled.
How many times did North Seaton Level Crossing CSO spill in 2025?
The 2025 return records 3 counted spill events and 16 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 31% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
Is North Seaton Level Crossing CSO discharging right now?
This record is linked to a company live feed. The panel above shows the latest report we hold, with its date. That report can be old, and the monitor can be offline, so check the date before relying on it. A report that no discharge is taking place is not a water-quality result.
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 North Seaton Level Crossing CSO?
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 North Seaton Level Crossing CSO compare with other overflows?
North Seaton Level Crossing CSO recorded 3 spills in 2025. That is more than 26% of the 14,239 overflows in England with a reported figure, and ranks 9,843rd nationally. Among Northumbrian Water overflows it ranks 1,071st of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Wansbeck from Bothal Burn to North Sea waterbody it ranks 10th of 11. Ranks compare counted spill events only. They do not compare volume or harm.
Does zero spills mean the water was safe?
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.
