Questions about Bristol Forest Road Storm Retention Tank

Who operates Bristol Forest Road Storm Retention Tank?
Wessex Water is the operator named in the annual record. The permit reference is 101276.
Where does Bristol Forest Road Storm Retention Tank discharge?
The source names Fishponds Brook via SWS as the receiving water. This does not show how far a discharge travelled.
How many times did Bristol Forest Road Storm Retention Tank spill in 2025?
The 2025 return records 16 counted spill events and 45.8 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 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Bristol Forest Road Storm Retention 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 Forest Road Storm Retention 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 Forest Road Storm Retention Tank compare with other overflows?
Bristol Forest Road Storm Retention Tank recorded 16 spills in 2025. That is more than 58% of the 14,239 overflows in England with a reported figure, and ranks 5,789th nationally. Among Wessex Water overflows it ranks 531st of 1,332; the median Wessex Water overflow recorded 11 spills. On the Frome (Brist) - Bradley Bk to conf Floating Hbr waterbody it ranks 9th of 60. 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.
