Questions about BRAYSTONES WwTW
- Who operates BRAYSTONES WwTW?
- United Utilities is the operator named in the annual record. The permit reference is 017470152.
- Where does BRAYSTONES WwTW discharge?
- The source names Irish Sea as the receiving water. This does not show how far a discharge travelled.
- How many times did BRAYSTONES WwTW spill in 2025?
- The 2025 return records 168 counted spill events and 1,082.3 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 99.7% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is BRAYSTONES WwTW 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 BRAYSTONES WwTW?

Among United Utilities overflows it ranks 3rd of 2,270; the median United Utilities overflow recorded 15 spills. On the Ehen (lower) waterbody it ranks 1st of 7.
