How many times did Heanor - Berle Avenue (Field 7500) (CSO) spill in 2025?
The 2025 return records 27 counted spill events and 22.4 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 98.7% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Heanor - Berle Avenue (Field 7500) (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 Heanor - Berle Avenue (Field 7500) (CSO)?

How does Heanor - Berle Avenue (Field 7500) (CSO) compare with other overflows?
Heanor - Berle Avenue (Field 7500) (CSO) recorded 27 spills in 2025. That is more than 71% of the 14,239 overflows in England with a reported figure, and ranks 3,910th nationally. Among Severn Trent Water overflows it ranks 448th of 2,431; the median Severn Trent Water overflow recorded 8 spills. On the Bailey Brook Catchment (trib of Erewash) waterbody it ranks 2nd of 15. 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.
