Questions about John Pier Sewage Pumping Station CSO
- Who operates John Pier Sewage Pumping Station CSO?
- United Utilities is the operator named in the annual record. The permit reference is 017580294.
- Where does John Pier Sewage Pumping Station CSO discharge?
- The source names River Derwent Estuary as the receiving water. This does not show how far a discharge travelled.
- How many times did John Pier Sewage Pumping Station CSO spill in 2025?
- The 2025 return records 39 counted spill events and 133.1 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 98.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is John Pier Sewage Pumping Station 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 John Pier Sewage Pumping Station CSO?
- 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 John Pier Sewage Pumping Station CSO compare with other overflows?
- John Pier Sewage Pumping Station CSO recorded 39 spills in 2025. That is more than 81% of the 14,239 overflows in England with a reported figure, and ranks 2,494th nationally. Among United Utilities overflows it ranks 599th of 2,270; the median United Utilities overflow recorded 15 spills. 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.
