Questions about Bradley Mills/2 CSO

Who operates Bradley Mills/2 CSO?
Yorkshire Water is the operator named in the annual record. The permit reference is WRA7164.
Where does Bradley Mills/2 CSO discharge?
The source names River Colne as the receiving water. This does not show how far a discharge travelled.
How many times did Bradley Mills/2 CSO spill in 2025?
The 2025 return records 3 counted spill events and 36.5 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 100% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Bradley Mills/2 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 Bradley Mills/2 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 Bradley Mills/2 CSO compare with other overflows?
Bradley Mills/2 CSO recorded 3 spills in 2025. That is more than 26% of the 14,239 overflows in England with a reported figure, and ranks 9,843rd nationally. Among Yorkshire Water overflows it ranks 1,632nd of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the River Colne from River Holme to River Calder waterbody it ranks 26th of 33. 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.
