Questions about Mosterton SPS Pscsoeo Mosterton
- Who operates Mosterton SPS Pscsoeo Mosterton?
- South West Water is the operator named in the annual record. The permit reference is 201546.
- Where does Mosterton SPS Pscsoeo Mosterton discharge?
- The source names River Axe as the receiving water. This does not show how far a discharge travelled.
- How many times did Mosterton SPS Pscsoeo Mosterton spill in 2025?
- The 2025 return records 72 counted spill events and 311.8 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 Mosterton SPS Pscsoeo Mosterton 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 10 metres. It shows the recorded outlet position, not the extent of any discharge.
- What kind of outlet is Mosterton SPS Pscsoeo Mosterton?

- Mosterton SPS Pscsoeo Mosterton recorded 72 spills in 2025. That is more than 94% of the 14,239 overflows in England with a reported figure, and ranks 710th nationally. Among South West Water overflows it ranks 202nd of 1,357; the median South West Water overflow recorded 21 spills. On the Upper Axe waterbody it ranks 2nd of 8.

- 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.
