Questions about Coleford Kings Head
- Who operates Coleford Kings Head?
- Wessex Water is the operator named in the annual record. The permit reference is 103442.
- Where does Coleford Kings Head discharge?
- The source names Mells Stream as the receiving water. This does not show how far a discharge travelled.
- How many times did Coleford Kings Head spill in 2025?
- The 2025 return records 26 counted spill events and 76.9 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 82.6% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Coleford Kings Head 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 Coleford Kings Head?
- The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
- How does Coleford Kings Head compare with other overflows?
- Coleford Kings Head recorded 26 spills in 2025. That is more than 70% of the 14,239 overflows in England with a reported figure, and ranks 4,061st nationally. Among Wessex Water overflows it ranks 345th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Mells source to conf with Somerset Frome waterbody it ranks 5th of 11. 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.
