Questions about Constantine Bridge SPS Pscsoeo Falmouth

Where does Constantine Bridge SPS Pscsoeo Falmouth discharge?: The source names Nanceroy Stream (S) as the receiving water. This does not show how far a discharge travelled.
How many times did Constantine Bridge SPS Pscsoeo Falmouth spill in 2025?: The 2025 return records 41 counted spill events and 488.7 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 Constantine Bridge SPS Pscsoeo Falmouth 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 Constantine Bridge SPS Pscsoeo Falmouth?: 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 Constantine Bridge SPS Pscsoeo Falmouth compare with other overflows?: Constantine Bridge SPS Pscsoeo Falmouth recorded 41 spills in 2025. That is more than 83% of the 14,239 overflows in England with a reported figure, and ranks 2,313th nationally. Among South West Water overflows it ranks 420th of 1,357; the median South West Water overflow recorded 21 spills. Ranks compare counted spill events only. They do not compare volume or harm.
