Questions about Bristol Cherington Road O/S No 2
- Who operates Bristol Cherington Road O/S No 2?
- Wessex Water is the operator named in the annual record. The permit reference is 100467.
- Where does Bristol Cherington Road O/S No 2 discharge?
- The source names Tributary of River Trym via SWS as the receiving water. This does not show how far a discharge travelled.
- How many times did Bristol Cherington Road O/S No 2 spill in 2025?
- The 2025 return records 29 counted spill events and 72.8 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 49.2% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Bristol Cherington Road O/S No 2 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 Bristol Cherington Road O/S No 2?
- 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 Bristol Cherington Road O/S No 2 compare with other overflows?
- Bristol Cherington Road O/S No 2 recorded 29 spills in 2025. That is more than 73% of the 14,239 overflows in England with a reported figure, and ranks 3,624th nationally. Among Wessex Water overflows it ranks 305th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Trym - source to conf R Avon (Brist) waterbody it ranks 9th of 31. 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.
