Questions about Ramsey-St Marys Rd SSO

Who operates Ramsey-St Marys Rd SSO?
Anglian Water is the operator named in the annual record. The permit reference is AW1NF1055.
Where does Ramsey-St Marys Rd SSO discharge?
The source names Ramsey High Lode as the receiving water. This does not show how far a discharge travelled.
How many times did Ramsey-St Marys Rd SSO spill in 2025?
The 2025 return records 9 counted spill events and 57.8 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 50.8% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
Is Ramsey-St Marys Rd SSO 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 Ramsey-St Marys Rd SSO?
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 Ramsey-St Marys Rd SSO compare with other overflows?
Ramsey-St Marys Rd SSO recorded 9 spills in 2025. That is more than 45% of the 14,239 overflows in England with a reported figure, and ranks 7,492nd nationally. Among Anglian Water overflows it ranks 543rd of 1,438; the median Anglian Water overflow recorded 6 spills. On the Middle Level waterbody it ranks 10th of 24. 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.
