Questions about Causeway Pumping Station
- Who operates Causeway Pumping Station?
- United Utilities is the operator named in the annual record. The permit reference is EPRTB3193DV.
- Where does Causeway Pumping Station discharge?
- The source names River Mersey as the receiving water. This does not show how far a discharge travelled.
- How many times did Causeway Pumping Station spill in 2025?
- The 2025 return records 5 counted spill events and 7.3 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 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Causeway Pumping Station 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 Causeway Pumping Station?
- 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 Causeway Pumping Station compare with other overflows?
- Causeway Pumping Station 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 MERSEY - Transitional waterbody it ranks 60th of 78. 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.
