Questions about Bromley Road / Coronation Road CSO
- Who operates Bromley Road / Coronation Road CSO?
- United Utilities is the operator named in the annual record. The permit reference is 01CON0031.
- Where does Bromley Road / Coronation Road CSO discharge?
- The source names River Dane via SWS as the receiving water. This does not show how far a discharge travelled.
- How many times did Bromley Road / Coronation Road CSO spill in 2025?
- The 2025 return records 23 counted spill events and 13 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 95.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Bromley Road / Coronation Road 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 Bromley Road / Coronation Road 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 Bromley Road / Coronation Road CSO compare with other overflows?
- Bromley Road / Coronation Road CSO recorded 23 spills in 2025. That is more than 67% of the 14,239 overflows in England with a reported figure, and ranks 4,513th nationally. Among United Utilities overflows it ranks 934th of 2,270; the median United Utilities overflow recorded 15 spills. On the Dane (Cow Brook to Wheelock) waterbody it ranks 4th of 10. 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.
