- How many times did Arkwright Street CSO spill in 2025?
- The 2025 return records 41 counted spill events and 41.1 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

- The monitor worked for 99.8% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Arkwright Street CSO discharging right now?
- This record is not matched to a company live feed, so we cannot show a current report. Only the annual figures are available for this outlet.
- 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 Arkwright Street CSO?

Among United Utilities overflows it ranks 567th of 2,270; the median United Utilities overflow recorded 15 spills. On the Wince Brook waterbody it ranks 5th of 17.
