Questions about Milton STW (SSTO)

- How many times did Milton STW (SSTO) spill in 2025?
- The 2025 return records 76 counted spill events and 806 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

- 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.
