Questions about Faringdon STW
- Who operates Faringdon STW?
- Thames Water is the operator named in the annual record. The permit reference is CSSC.2343.
- Where does Faringdon STW discharge?
- The source names Faringdon Brook as the receiving water. This does not show how far a discharge travelled.
- How many times did Faringdon STW spill in 2025?
- The 2025 return records 50 counted spill events and 159 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 93.7% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Faringdon 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 Faringdon STW?
- The annual return lists the asset type as “Inlet SO at WwTW - with treatment”, which means inlet storm overflow at a wastewater treatment works, with treatment. The overflow is at the inlet of a treatment works, where wastewater enters the works. The return records this variant as discharging with treatment.
- How does Faringdon STW compare with other overflows?
- Faringdon STW recorded 50 spills in 2025. That is more than 88% of the 14,239 overflows in England with a reported figure, and ranks 1,626th nationally. Among Thames Water overflows it ranks 43rd 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.
