Questions about Kingston Bagpuize STW

Who operates Kingston Bagpuize STW?
Thames Water is the operator named in the annual record. The permit reference is CTCR.2011.
Where does Kingston Bagpuize STW discharge?
The source names Bagpuize Brook as the receiving water. This does not show how far a discharge travelled.
How many times did Kingston Bagpuize STW spill in 2025?
The 2025 return records 32 counted spill events and 389 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 Kingston Bagpuize STW 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 Kingston Bagpuize STW?
The annual return lists the asset type as “Storm tank at WwTW”, which means storm tank at a wastewater treatment works. The overflow comes from storm storage at a treatment works.
How does Kingston Bagpuize STW compare with other overflows?
Kingston Bagpuize STW recorded 32 spills in 2025. That is more than 76% of the 14,239 overflows in England with a reported figure, and ranks 3,223rd nationally. Among Thames Water overflows it ranks 98th of 579; the median Thames Water overflow recorded 6 spills. 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.
