Questions about Meden Vale - Welbeck Colliery (SSO)
- Who operates Meden Vale - Welbeck Colliery (SSO)?
- Severn Trent Water is the operator named in the annual record. The permit reference is T/71/02650/O.
- Where does Meden Vale - Welbeck Colliery (SSO) discharge?
- The source names River Meden as the receiving water. This does not show how far a discharge travelled.
- How many times did Meden Vale - Welbeck Colliery (SSO) spill in 2025?
- The 2025 return records 37 counted spill events and 50.2 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 99.6% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Meden Vale - Welbeck Colliery (SSO) 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 Meden Vale - Welbeck Colliery (SSO)?
- 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 Meden Vale - Welbeck Colliery (SSO) compare with other overflows?
- Meden Vale - Welbeck Colliery (SSO) recorded 37 spills in 2025. That is more than 80% of the 14,239 overflows in England with a reported figure, and ranks 2,695th nationally. Among Severn Trent Water overflows it ranks 268th of 2,431; the median Severn Trent Water overflow recorded 8 spills. On the Meden from Sookholme Brook to Maun waterbody it ranks 1st of 9. 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.
