- How many times did Woodside House CSO (169KP) spill in 2025?
- The 2025 return records 17 counted spill events and 44 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

- 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.
