Questions about Parbrook Inlet
- Who operates Parbrook Inlet?
- Wessex Water is the operator named in the annual record. The permit reference is 070086.
- Where does Parbrook Inlet discharge?
- The source names Tributary of Coxbridge Brook as the receiving water. This does not show how far a discharge travelled.
- How many times did Parbrook Inlet spill in 2025?
- The 2025 return records 2 counted spill events and 6.9 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 86.2% of the reporting period. Below 90%, some events can be missed, so the count and hours may understate activity.
- Is Parbrook Inlet 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 Parbrook Inlet?
- The annual return lists the asset type as “Inlet SO at WwTW”, which means inlet storm overflow at a wastewater treatment works. The overflow is at the inlet of a treatment works, where wastewater enters the works.

- Parbrook Inlet recorded 2 spills in 2025. That is more than 21% of the 14,239 overflows in England with a reported figure, and ranks 10,428th nationally. Among Wessex Water overflows it ranks 977th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Coxbridge Brook( Brue) waterbody it ranks 2nd of 3. 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.
