Questions about Dean Street (High Level) CSO
- Who operates Dean Street (High Level) CSO?
- Northumbrian Water is the operator named in the annual record. The permit reference is 235/1921.
- Where does Dean Street (High Level) CSO discharge?
- The source names River Tyne as the receiving water. This does not show how far a discharge travelled.
- How many times did Dean Street (High Level) CSO spill in 2025?
- The 2025 return records 2 counted spill events and 1.5 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 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Dean Street (High Level) 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 Dean Street (High Level) 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 Dean Street (High Level) CSO compare with other overflows?
- Dean Street (High Level) CSO recorded 2 spills in 2025. That is more than 21% of the 14,239 overflows in England with a reported figure, and ranks 10,428th nationally. Among Northumbrian Water overflows it ranks 1,127th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Tyne waterbody it ranks 132nd of 177. 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.
