Questions about Pump Lane Gillingham Tank CSO - 102333

Who operates Pump Lane Gillingham Tank CSO - 102333?
Southern Water is the operator named in the annual record. The permit reference is A00466.
Where does Pump Lane Gillingham Tank CSO - 102333 discharge?
The source names River Medway Estuary as the receiving water. This does not show how far a discharge travelled.
How many times did Pump Lane Gillingham Tank CSO - 102333 spill in 2025?
The 2025 return records 15 counted spill events and 42.4 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.
Is Pump Lane Gillingham Tank CSO - 102333 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 Pump Lane Gillingham Tank CSO - 102333?
The annual return lists the asset type as “SO on sewer network”, which means storm overflow on the sewer network. The return places this overflow on the sewer network.
How does Pump Lane Gillingham Tank CSO - 102333 compare with other overflows?
Pump Lane Gillingham Tank CSO - 102333 recorded 15 spills in 2025. That is more than 56% of the 14,239 overflows in England with a reported figure, and ranks 5,981st nationally. Among Southern Water overflows it ranks 336th of 975; the median Southern Water overflow recorded 7 spills. On the Medway waterbody it ranks 18th of 86. Ranks compare counted spill events only. They do not compare volume or harm.
Does zero spills mean the water was safe?
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.
