Questions about Copster Green Sewer Ejector Station
- Who operates Copster Green Sewer Ejector Station?
- United Utilities is the operator named in the annual record. The permit reference is 01RIB0048.
- Where does Copster Green Sewer Ejector Station discharge?
- The source names Showley Brook as the receiving water. This does not show how far a discharge travelled.
- How many times did Copster Green Sewer Ejector Station spill in 2025?
- The 2025 return records 1 counted spill events and 6.5 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 77.6% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Copster Green Sewer Ejector 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 Copster Green Sewer Ejector 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 Copster Green Sewer Ejector Station compare with other overflows?
- Copster Green Sewer Ejector Station recorded 1 spill in 2025. That is more than 15% of the 14,239 overflows in England with a reported figure, and ranks 11,130th nationally. Among United Utilities overflows it ranks 1,851st of 2,270; the median United Utilities overflow recorded 15 spills. On the Showley Brook waterbody it ranks 4th of 4. 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.
