Questions about Maiden Bradley Inlet
- Who operates Maiden Bradley Inlet?
- Wessex Water is the operator named in the annual record. The permit reference is 400608.
- Where does Maiden Bradley Inlet discharge?
- The source names Groundwater via Infilt System as the receiving water. This does not show how far a discharge travelled.
- How many times did Maiden Bradley Inlet spill in 2025?
- The 2025 return records 26 counted spill events and 45.1 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 Maiden Bradley 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 Maiden Bradley Inlet?
- The annual return lists the asset type as “Inlet SO at WwTW - with treatment”, which means inlet storm overflow at a wastewater treatment works, with treatment. The overflow is at the inlet of a treatment works, where wastewater enters the works. The return records this variant as discharging with treatment.
- How does Maiden Bradley Inlet compare with other overflows?
- Maiden Bradley Inlet recorded 26 spills in 2025. That is more than 70% of the 14,239 overflows in England with a reported figure, and ranks 4,061st nationally. Among Wessex Water overflows it ranks 345th of 1,332; the median Wessex Water overflow recorded 11 spills. On the Wylye (Headwaters) waterbody it ranks 2nd of 5. 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.
