Questions about BETLEY WwTW

Who operates BETLEY WwTW?
United Utilities is the operator named in the annual record. The permit reference is 016810049.
Where does BETLEY WwTW discharge?
The source names Mere Gutter as the receiving water. This does not show how far a discharge travelled.
How many times did BETLEY WwTW spill in 2025?
The 2025 return records 47 counted spill events and 251.9 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 96.2% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is BETLEY 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 BETLEY WwTW?
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 BETLEY WwTW compare with other overflows?
BETLEY WwTW recorded 47 spills in 2025. That is more than 86% of the 14,239 overflows in England with a reported figure, and ranks 1,843rd nationally. Among United Utilities overflows it ranks 486th of 2,270; the median United Utilities overflow recorded 15 spills. On the Wistaston Brook waterbody it ranks 2nd of 3. 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.
