A missing figure means the source did not provide a usable value. A zero is shown as zero. Monitor operation below 90% can make comparison less reliable.

Questions about Palm Terrace CSO
- Who operates Palm Terrace CSO?
- Northumbrian Water is the operator named in the annual record. The permit reference is 235/1717.
- Where does Palm Terrace CSO discharge?
- The source names Farlieth Burn as the receiving water. This does not show how far a discharge travelled.
- How many times did Palm Terrace CSO spill in 2025?
- The 2025 return records 21 counted spill events and 126.6 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% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
- Is Palm Terrace CSO 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 Palm Terrace CSO?
- 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 Palm Terrace CSO compare with other overflows?
- Palm Terrace CSO recorded 21 spills in 2025. That is more than 64% of the 14,239 overflows in England with a reported figure, and ranks 4,856th nationally. Among Northumbrian Water overflows it ranks 509th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Team from Source to Tyne waterbody it ranks 15th of 56. 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.
