The source names River Dove as the receiving water. This does not show how far a discharge travelled.
How many times did Ashbourne - Lime Close (CSO) spill in 2025?
The 2025 return records 29 counted spill events and 366.7 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 Ashbourne - Lime Close (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 Ashbourne - Lime Close (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 Ashbourne - Lime Close (CSO) compare with other overflows?
Ashbourne - Lime Close (CSO) recorded 29 spills in 2025. That is more than 73% of the 14,239 overflows in England with a reported figure, and ranks 3,624th nationally. Among Severn Trent Water overflows it ranks 406th of 2,431; the median Severn Trent Water overflow recorded 8 spills. On the Dove - R Churnet to R Trent waterbody it ranks 2nd of 14. 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.
