How many times did Newport STW (SSTO) spill in 2025?
The 2025 return records 24 counted spill events and 228.2 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.
What kind of outlet is Newport STW (SSTO)?
