Questions about Dudley Middle School CSO
- Who operates Dudley Middle School CSO?
- Northumbrian Water is the operator named in the annual record. The permit reference is 226/1259.
- Where does Dudley Middle School CSO discharge?
- The source names Sandy'S Letch,TRIB Seaton Burn as the receiving water. This does not show how far a discharge travelled.
- How many times did Dudley Middle School CSO spill in 2025?
- The 2025 return records 2 counted spill events and 0.7 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 91.2% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Dudley Middle School 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 Dudley Middle School CSO?

Among Northumbrian Water overflows it ranks 1,127th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Seaton Burn from Source to Tidal Limit waterbody it ranks 9th of 21.
