Questions about Shrewsbury - Quarry Pk (CSO)
- Who operates Shrewsbury - Quarry Pk (CSO)?
- Severn Trent Water is the operator named in the annual record. The permit reference is S/02/21029/O.
- Where does Shrewsbury - Quarry Pk (CSO) discharge?
- The source names River Severn as the receiving water. This does not show how far a discharge travelled.
- How many times did Shrewsbury - Quarry Pk (CSO) spill in 2025?
- The 2025 return records 15 counted spill events and 20.2 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 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Shrewsbury - Quarry Pk (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 Shrewsbury - Quarry Pk (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 Shrewsbury - Quarry Pk (CSO) compare with other overflows?
- Shrewsbury - Quarry Pk (CSO) recorded 15 spills in 2025. That is more than 56% of the 14,239 overflows in England with a reported figure, and ranks 5,981st nationally. Among Severn Trent Water overflows it ranks 832nd of 2,431; the median Severn Trent Water overflow recorded 8 spills. On the Severn - conf Bele Bk to conf Sundorne Bk waterbody it ranks 20th of 35. 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.
