Questions about Clinic CSO Tavistock

Who operates Clinic CSO Tavistock?
South West Water is the operator named in the annual record. The permit reference is 300078/CS/01.
Where does Clinic CSO Tavistock discharge?
The source names River Tavy as the receiving water. This does not show how far a discharge travelled.
How many times did Clinic CSO Tavistock spill in 2025?
The 2025 return records 79 counted spill events and 271.9 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 Clinic CSO Tavistock 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 Clinic CSO Tavistock?
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 Clinic CSO Tavistock compare with other overflows?
Clinic CSO Tavistock recorded 79 spills in 2025. That is more than 96% of the 14,239 overflows in England with a reported figure, and ranks 531st nationally. Among South West Water overflows it ranks 167th of 1,357; the median South West Water overflow recorded 21 spills. On the Lower River Tavy waterbody it ranks 2nd of 11. 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.
