Questions about 111 Outland Road CSO Plymouth
- Who operates 111 Outland Road CSO Plymouth?
- South West Water is the operator named in the annual record. The permit reference is 301761.
- Where does 111 Outland Road CSO Plymouth discharge?
- The source names Stonehouse Creek (E) as the receiving water. This does not show how far a discharge travelled.
- How many times did 111 Outland Road CSO Plymouth spill in 2025?
- The 2025 return records 28 counted spill events and 24.2 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 94.3% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is 111 Outland Road CSO Plymouth 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 10 metres. It shows the recorded outlet position, not the extent of any discharge.
- What kind of outlet is 111 Outland Road CSO Plymouth?
- 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 111 Outland Road CSO Plymouth compare with other overflows?
- 111 Outland Road CSO Plymouth recorded 28 spills in 2025. That is more than 72% of the 14,239 overflows in England with a reported figure, and ranks 3,771st nationally. Among South West Water overflows it ranks 578th of 1,357; the median South West Water overflow recorded 21 spills. On the Plymouth Tamar waterbody it ranks 4th of 9. 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.
