Questions about Bristol Hanham Britannia Road Tank
- Who operates Bristol Hanham Britannia Road Tank?
- Wessex Water is the operator named in the annual record. The permit reference is 101761.
- Where does Bristol Hanham Britannia Road Tank discharge?
- The source names Strad Brook (S) as the receiving water. This does not show how far a discharge travelled.
- How many times did Bristol Hanham Britannia Road Tank spill in 2025?
- The 2025 return records 5 counted spill events and 7 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 76.6% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Bristol Hanham Britannia Road Tank 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 Hanham Britannia Road Tank?
- 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 Hanham Britannia Road Tank compare with other overflows?
- Bristol Hanham Britannia Road Tank recorded 5 spills in 2025. That is more than 34% of the 14,239 overflows in England with a reported figure, and ranks 8,927th nationally. Among Wessex Water overflows it ranks 864th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Bristol Avon (By Bk to Netham Weir) waterbody it ranks 88th 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.
