Questions about Waters meeting Road CSO
- Who operates Waters meeting Road CSO?
- United Utilities is the operator named in the annual record. The permit reference is 016982261.
- Where does Waters meeting Road CSO discharge?
- The source names River Tonge as the receiving water. This does not show how far a discharge travelled.
- How many times did Waters meeting Road CSO spill in 2025?
- The 2025 return records 55 counted spill events and 166.2 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 99.3% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Waters meeting Road 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 Waters meeting Road CSO?
- The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
- How does Waters meeting Road CSO compare with other overflows?
- Waters meeting Road CSO recorded 55 spills in 2025. That is more than 90% of the 14,239 overflows in England with a reported figure, and ranks 1,343rd nationally. Among United Utilities overflows it ranks 366th of 2,270; the median United Utilities overflow recorded 15 spills. On the Tonge waterbody it ranks 2nd of 11. 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.
