How many times did Annesley - Moseley Road (CSO) spill in 2025?
The 2025 return records 4 counted spill events and 1.8 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 Annesley - Moseley 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 Annesley - Moseley 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 Annesley - Moseley Road (CSO) compare with other overflows?
Annesley - Moseley Road (CSO) recorded 4 spills in 2025. That is more than 30% of the 14,239 overflows in England with a reported figure, and ranks 9,334th nationally. Among Severn Trent Water overflows it ranks 1,496th of 2,431; the median Severn Trent Water overflow recorded 8 spills. On the Leen from Source to Day Brook waterbody it ranks 10th of 16. Ranks compare counted spill events only. They do not compare volume or harm.

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.
