Questions about Bathampton M H K
- Who operates Bathampton M H K?
- Wessex Water is the operator named in the annual record. The permit reference is 100510/CS/01.
- Where does Bathampton M H K discharge?
- The source names River Avon as the receiving water. This does not show how far a discharge travelled.
- How many times did Bathampton M H K spill in 2025?
- The 2025 return records 15 counted spill events and 5.4 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 98.6% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Bathampton M H K 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 Bathampton M H K?
- 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 Bathampton M H K compare with other overflows?
- Bathampton M H K recorded 15 spills in 2025. That is more than 56% of the 14,239 overflows in England with a reported figure, and ranks 5,981st nationally. Among Wessex Water overflows it ranks 553rd of 1,332; the median Wessex Water overflow recorded 11 spills. On the Bristol Avon (By Bk to Netham Weir) waterbody it ranks 52nd of 126. 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.
