- Southern Water is the operator named in the annual record. The permit reference is A01033.

- The source names River Medway as the receiving water. This does not show how far a discharge travelled.
- How many times did Station Road Forest Row CSO - 108345 spill in 2025?
- The 2025 return records 14 counted spill events and 38.1 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 48.6% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.

- 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.
- What kind of outlet is Station Road Forest Row CSO - 108345?

- No. A zero means the annual return recorded zero counted spill events for this outlet and year. It is not a water-quality test, and pollution can come from other sources.
