A missing figure means the source did not provide a usable value. A zero is shown as zero. Monitor operation below 90% can make comparison less reliable.

Questions about Wellfield SPS
- Who operates Wellfield SPS?
- Northumbrian Water is the operator named in the annual record. The permit reference is 255/1108.
- Where does Wellfield SPS discharge?
- The source names Castle Eden Burn Tributary as the receiving water. This does not show how far a discharge travelled.
- How many times did Wellfield SPS spill in 2025?
- The 2025 return records 14 counted spill events and 25.5 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 Wellfield SPS 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 Wellfield SPS?
- The annual return lists the asset type as “Storm discharge at pumping station”, which means storm discharge at a pumping station. The overflow is at a pumping station that moves sewage through the network.
- How does Wellfield SPS compare with other overflows?
- Wellfield SPS recorded 14 spills in 2025. That is more than 54% of the 14,239 overflows in England with a reported figure, and ranks 6,208th nationally. Among Northumbrian Water overflows it ranks 674th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Castle Eden Burn from Source to North Sea waterbody it ranks 3rd of 10. 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.
