Questions about Tollesbury Water Recycling Centre

Who operates Tollesbury Water Recycling Centre?
Anglian Water is the operator named in the annual record. The permit reference is ASETS1229.
Where does Tollesbury Water Recycling Centre discharge?
The source names Tollesbury Fleet to Blackwater as the receiving water. This does not show how far a discharge travelled.
How many times did Tollesbury Water Recycling Centre spill in 2025?
The 2025 return records 17 counted spill events and 177.6 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 Tollesbury Water Recycling Centre 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 Tollesbury Water Recycling Centre?
The annual return lists the asset type as “Storm tank at WwTW”, which means storm tank at a wastewater treatment works. The overflow comes from storm storage at a treatment works.
How does Tollesbury Water Recycling Centre compare with other overflows?
Tollesbury Water Recycling Centre recorded 17 spills in 2025. That is more than 59% of the 14,239 overflows in England with a reported figure, and ranks 5,597th nationally. Among Anglian Water overflows it ranks 329th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Blackwater waterbody it ranks 3rd of 14. Ranks compare counted spill events only.

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.
