Questions about Hillcommon Hill Common
- Who operates Hillcommon Hill Common?
- Wessex Water is the operator named in the annual record. The permit reference is NPSWQD003671.
- Where does Hillcommon Hill Common discharge?
- The source names Tributary of River Tone as the receiving water. This does not show how far a discharge travelled.
- How many times did Hillcommon Hill Common spill in 2025?
- The 2025 return records 5 counted spill events and 8.3 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 Hillcommon Hill Common 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 Hillcommon Hill Common?
- 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 Hillcommon Hill Common compare with other overflows?
- Hillcommon Hill Common recorded 5 spills in 2025. That is more than 34% of the 14,239 overflows in England with a reported figure, and ranks 8,927th nationally. Among Wessex Water overflows it ranks 864th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Tone - Wellington to Taunton waterbody it ranks 4th of 6. 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.
