Questions about Hebble Lane/CSO

Who operates Hebble Lane/CSO?: Yorkshire Water is the operator named in the annual record. The permit reference is WRA8132.
Where does Hebble Lane/CSO discharge?: The source names Hebble Brook as the receiving water. This does not show how far a discharge travelled.
How many times did Hebble Lane/CSO spill in 2025?: The 2025 return records 116 counted spill events and 1,170 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 Hebble Lane/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 Hebble Lane/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 Hebble Lane/CSO compare with other overflows?: Hebble Lane/CSO recorded 116 spills in 2025. That is more than 98% of the 14,239 overflows in England with a reported figure, and ranks 150th nationally. Among Yorkshire Water overflows it ranks 11th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Hebble Brook from Source to River Calder waterbody it ranks 1st of 18. 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.
