Questions about Godmanstone

Who operates Godmanstone?
Wessex Water is the operator named in the annual record. The permit reference is 401521.
Where does Godmanstone discharge?
The source names River Cerne as the receiving water. This does not show how far a discharge travelled.
How many times did Godmanstone spill in 2025?
The 2025 return records 24 counted spill events and 545.3 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 94.3% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Godmanstone 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 Godmanstone?
The annual return lists the asset type as “Inlet SO at WwTW”, which means inlet storm overflow at a wastewater treatment works. The overflow is at the inlet of a treatment works, where wastewater enters the works.
How does Godmanstone compare with other overflows?
Godmanstone recorded 24 spills in 2025. That is more than 68% of the 14,239 overflows in England with a reported figure, and ranks 4,364th nationally. Among Wessex Water overflows it ranks 376th of 1,332; the median Wessex Water overflow recorded 11 spills. 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.
