Questions about Fritwell STW
- Who operates Fritwell STW?
- Anglian Water is the operator named in the annual record. The permit reference is AW1NF2895.
- Where does Fritwell STW discharge?
- The source names Padbury Brook River Great Ouse as the receiving water. This does not show how far a discharge travelled.
- How many times did Fritwell STW spill in 2025?
- The 2025 return records 22 counted spill events and 94 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 99.8% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Fritwell 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 Fritwell 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 Fritwell STW compare with other overflows?
- Fritwell STW recorded 22 spills in 2025. That is more than 65% of the 14,239 overflows in England with a reported figure, and ranks 4,697th nationally. Among Anglian Water overflows it ranks 249th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Padbury Brook waterbody it ranks 1st of 5. 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.
