Questions about Ipswich Wolsey Street Pumping Station

Who operates Ipswich Wolsey Street Pumping Station?
Anglian Water is the operator named in the annual record. The permit reference is AW4TS12083.
Where does Ipswich Wolsey Street Pumping Station discharge?
The source names River Orwell as the receiving water. This does not show how far a discharge travelled.
How many times did Ipswich Wolsey Street Pumping Station spill in 2025?
The 2025 return records 66 counted spill events and 43.9 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Ipswich Wolsey Street Pumping Station 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 Ipswich Wolsey Street Pumping Station?
The annual return lists the asset type as “Storm discharge at pumping station”, which means storm discharge at a pumping station. The overflow is at a pumping station that moves sewage through the network.
How does Ipswich Wolsey Street Pumping Station compare with other overflows?
Ipswich Wolsey Street Pumping Station recorded 66 spills in 2025. That is more than 93% of the 14,239 overflows in England with a reported figure, and ranks 887th nationally. Among Anglian Water overflows it ranks 30th of 1,438; the median Anglian Water overflow recorded 6 spills. On the Gipping (d/s Stowmarket) waterbody it ranks 1st of 15. 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.
