How many times did Cross Lane East Gravesend CSO - 108704 spill in 2025?
The 2025 return records 9 counted spill events and 2.6 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 55.5% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
Is Cross Lane East Gravesend CSO - 108704 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 Cross Lane East Gravesend CSO - 108704?

Cross Lane East Gravesend CSO - 108704 recorded 9 spills in 2025. That is more than 45% of the 14,239 overflows in England with a reported figure, and ranks 7,492nd nationally. Among Southern Water overflows it ranks 438th of 975; the median Southern Water overflow recorded 7 spills. On the Thames Middle waterbody it ranks 14th of 71. Ranks compare counted spill events only. They do not compare volume or harm.

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.
