Questions about Yeolmbridge CSO Yeolmbridge

Who operates Yeolmbridge CSO Yeolmbridge?: South West Water is the operator named in the annual record. The permit reference is 301899.
Where does Yeolmbridge CSO Yeolmbridge discharge?: The source names River Yeolm (S) as the receiving water. This does not show how far a discharge travelled.
How many times did Yeolmbridge CSO Yeolmbridge spill in 2025?: The 2025 return records 47 counted spill events and 403.3 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 98.3% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Yeolmbridge CSO Yeolmbridge 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 10 metres. It shows the recorded outlet position, not the extent of any discharge.
What kind of outlet is Yeolmbridge CSO Yeolmbridge?: 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.
