Questions about Abbey Road Steyning CSO - 107379

Who operates Abbey Road Steyning CSO - 107379?
Southern Water is the operator named in the annual record. The permit reference is A00511.
Where does Abbey Road Steyning CSO - 107379 discharge?
The source names Tributary of River Adur as the receiving water. This does not show how far a discharge travelled.
How many times did Abbey Road Steyning CSO - 107379 spill in 2025?
The 2025 return records 14 counted spill events and 19 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 Abbey Road Steyning CSO - 107379 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 Abbey Road Steyning CSO - 107379?
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 Abbey Road Steyning CSO - 107379 compare with other overflows?
Abbey Road Steyning CSO - 107379 recorded 14 spills in 2025. That is more than 54% of the 14,239 overflows in England with a reported figure, and ranks 6,208th nationally. Among Southern Water overflows it ranks 346th of 975; the median Southern Water overflow recorded 7 spills. On the Black Sewer waterbody it ranks 2nd of 4. 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.
