- Southern Water is the operator named in the annual record. The permit reference is A01178.
- Where does Cockshot Farm Hawkhurst No 3 CSO - 110321 discharge?
- The source names The Hawkhurst South Stream as the receiving water. This does not show how far a discharge travelled.
- How many times did Cockshot Farm Hawkhurst No 3 CSO - 110321 spill in 2025?
- The 2025 return records 23 counted spill events and 95.9 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.

- 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 Cockshot Farm Hawkhurst No 3 CSO - 110321?
