How it compares in 2025
Kew Transfer SPS recorded no spills in 2025. It is one of 2,231 overflows in England with a reported count of zero, out of 14,239 with a count.
The monitor worked for 76.7% of 2025, so this count may be low and its rank may understate activity.
| Group | Rank by spills | Median spills | Median hours |
|---|---|---|---|
| This outlet | – | 0 | 0 |
| England | 12,009th of 14,239 | 11 | 22.3 |
| Thames Water | 445th of 579 | 6 | 20.9 |
| Thames Upper | 13th of 16 | 1 | 6.3 |
Rank 1 has the most spills. Equal counts share a rank. Only overflows with a reported count are ranked. Counts do not measure volume, so a higher rank does not mean more sewage.

Questions about Kew Transfer SPS
- Who operates Kew Transfer SPS?
- Thames Water is the operator named in the annual record. The permit reference is CASM.0249.
- Where does Kew Transfer SPS discharge?
- The source names Tidal River Thames as the receiving water. This does not show how far a discharge travelled.
- How many times did Kew Transfer SPS spill in 2025?
- The 2025 return records 0 counted spill events and 0 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 76.7% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Kew Transfer SPS 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 Kew Transfer SPS?
- The annual return lists the asset type as “Storm discharge at pumping station”, which means storm discharge at a pumping station. The overflow is at a pumping station that moves sewage through the network.
- How does Kew Transfer SPS compare with other overflows?
- Kew Transfer SPS recorded no spills in 2025. It is one of 2,231 overflows in England with a reported count of zero, out of 14,239 with a count. 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.
