Questions about Bramston Street/CSO
- Who operates Bramston Street/CSO?
- Yorkshire Water is the operator named in the annual record. The permit reference is EPRFB3895WE.
- Where does Bramston Street/CSO discharge?
- The source names River Calder as the receiving water. This does not show how far a discharge travelled.
- How many times did Bramston Street/CSO spill in 2025?
- The 2025 return records 34 counted spill events and 61.8 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 65.2% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Bramston Street/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 Bramston Street/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 Bramston Street/CSO compare with other overflows?
- Bramston Street/CSO recorded 34 spills in 2025. That is more than 78% of the 14,239 overflows in England with a reported figure, and ranks 3,010th nationally. Among Yorkshire Water overflows it ranks 585th of 2,176; the median Yorkshire Water overflow recorded 16 spills. On the Calder from Ryburn Confluence to River Colne waterbody it ranks 13th of 39. 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.
