Who operates Maidstone Road Rainham CSO - 108676?
Southern Water is the operator named in the annual record. The permit reference is EPR/DB3797AW.
Where does Maidstone Road Rainham CSO - 108676 discharge?
The source names The Otterham Creek as the receiving water. This does not show how far a discharge travelled.
How many times did Maidstone Road Rainham CSO - 108676 spill in 2025?
The 2025 return records 26 counted spill events and 32.8 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Maidstone Road Rainham CSO - 108676 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 Maidstone Road Rainham CSO - 108676?
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 Maidstone Road Rainham CSO - 108676 compare with other overflows?
Maidstone Road Rainham CSO - 108676 recorded 26 spills in 2025. That is more than 70% of the 14,239 overflows in England with a reported figure, and ranks 4,061st nationally. Among Southern Water overflows it ranks 221st of 975; the median Southern Water overflow recorded 7 spills. On the Medway waterbody it ranks 6th of 86. Ranks compare counted spill events only.

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.
