Is Bradwell Avenue CSO (451HA) (TRA0068) 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 Bradwell Avenue CSO (451HA) (TRA0068)?

How does Bradwell Avenue CSO (451HA) (TRA0068) compare with other overflows?
Bradwell Avenue CSO (451HA) (TRA0068) recorded 4 spills in 2025. That is more than 30% of the 14,239 overflows in England with a reported figure, and ranks 9,334th nationally. Among United Utilities overflows it ranks 1,592nd of 2,270; the median United Utilities overflow recorded 15 spills. On the Irwell / Manchester Ship Canal (Irk to confluence with Upper Mersey) waterbody it ranks 28th of 47. 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.
