Questions about Snowdon Road PS
- Who operates Snowdon Road PS?
- Northumbrian Water is the operator named in the annual record. The permit reference is 254/1511.
- Where does Snowdon Road PS discharge?
- The source names The River Tees as the receiving water. This does not show how far a discharge travelled.
- How many times did Snowdon Road PS spill in 2025?
- The 2025 return records 23 counted spill events and 15.8 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 Snowdon Road PS 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 Snowdon Road PS?
- The annual return lists the asset type as “Storm discharge at pumping station”, which means storm discharge at a pumping station. The overflow is at a pumping station that moves sewage through the network.
- How does Snowdon Road PS compare with other overflows?
- Snowdon Road PS recorded 23 spills in 2025. That is more than 67% of the 14,239 overflows in England with a reported figure, and ranks 4,513th nationally. Among Northumbrian Water overflows it ranks 460th of 1,559; the median Northumbrian Water overflow recorded 11 spills. On the Tees waterbody it ranks 16th of 40. 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.
