Questions about Shapwick Somerset
- Who operates Shapwick Somerset?
- Wessex Water is the operator named in the annual record. The permit reference is 072077.
- Where does Shapwick Somerset discharge?
- The source names Sth Drain-TRIB of Lwr Brue (S) as the receiving water. This does not show how far a discharge travelled.
- How many times did Shapwick Somerset spill in 2025?
- The 2025 return records 32 counted spill events and 555.5 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 75.8% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Shapwick Somerset 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 Shapwick Somerset?
- 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 Shapwick Somerset compare with other overflows?
- Shapwick Somerset recorded 32 spills in 2025. That is more than 76% of the 14,239 overflows in England with a reported figure, and ranks 3,223rd nationally. Among Wessex Water overflows it ranks 266th of 1,332; the median Wessex Water overflow recorded 11 spills. On the South Drain waterbody it ranks 3rd of 12. 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.
