The source names The Otterham Creek as the receiving water. This does not show how far a discharge travelled.
How many times did Orchard Street Gillingham CSO - 108694 spill in 2025?
The 2025 return records 9 counted spill events and 15.7 hours of recorded discharge. Spills are counted with the 12/24-hour method, so this is not a count of every start signal.

The monitor worked for 98.8% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Orchard Street Gillingham CSO - 108694 discharging right now?
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 Orchard Street Gillingham CSO - 108694?

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.
