Questions about Compton Dando Inlet
- Who operates Compton Dando Inlet?
- Wessex Water is the operator named in the annual record. The permit reference is 010024.
- Where does Compton Dando Inlet discharge?
- The source names Bathford Brook (S) as the receiving water. This does not show how far a discharge travelled.
- How many times did Compton Dando Inlet spill in 2025?
- The 2025 return records 44 counted spill events and 225.5 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 Compton Dando Inlet 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.
