Questions about Moor Lane PS / Rowton A41 CSO
- Who operates Moor Lane PS / Rowton A41 CSO?
- United Utilities is the operator named in the annual record. The permit reference is 01CHE0023.
- Where does Moor Lane PS / Rowton A41 CSO discharge?
- The source names Caldy Brook River Dee as the receiving water. This does not show how far a discharge travelled.
- How many times did Moor Lane PS / Rowton A41 CSO spill in 2025?
- The 2025 return records 5 counted spill events and 54.7 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 93.2% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Moor Lane PS / Rowton A41 CSO 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 Moor Lane PS / Rowton A41 CSO?

- Moor Lane PS / Rowton A41 CSO recorded 5 spills in 2025. That is more than 34% of the 14,239 overflows in England with a reported figure, and ranks 8,927th nationally. Among United Utilities overflows it ranks 1,522nd of 2,270; the median United Utilities overflow recorded 15 spills. On the Finchetts Gutter waterbody it ranks 6th of 12. Ranks compare counted spill events only. They do not compare volume or harm.
