- How many times did Boundary Park Road CSO spill in 2025?
- The 2025 return records 3 counted spill events and 1.4 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 Boundary Park Road 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 Boundary Park Road CSO?
- The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.

- Boundary Park Road CSO recorded 3 spills in 2025. That is more than 26% of the 14,239 overflows in England with a reported figure, and ranks 9,843rd nationally. Among United Utilities overflows it ranks 1,655th of 2,270; the median United Utilities overflow recorded 15 spills. On the Irk (Sourtce to Wince Brook) waterbody it ranks 13th of 18.
