- How many times did Bristol Kingswood New Cheltenham Road O/S 43 spill in 2025?
- The 2025 return records 50 counted spill events and 49.2 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 97.5% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Bristol Kingswood New Cheltenham Road O/S 43 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 Bristol Kingswood New Cheltenham Road O/S 43?

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.
