Questions about Tillingham STW

Who operates Tillingham STW?
Anglian Water is the operator named in the annual record. The permit reference is ASENF1226.
Where does Tillingham STW discharge?
The source names Holland Brook as the receiving water. This does not show how far a discharge travelled.
How many times did Tillingham STW spill in 2025?
The 2025 return records 20 counted spill events and 205 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Tillingham STW 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 Tillingham STW?
The annual return lists the asset type as “Other storm discharge asset type”, which means other storm discharge asset type. The return uses its general category for this asset.
How does Tillingham STW compare with other overflows?
Tillingham STW recorded 20 spills in 2025. That is more than 63% of the 14,239 overflows in England with a reported figure, and ranks 5,045th nationally. Among Anglian Water overflows it ranks 274th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Blackwater waterbody it ranks 2nd of 14. 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.
