Earlier returns list fewer of these outlets, so totals are not comparable between years. The median per outlet and the like-for-like change are fairer comparisons. Counts are events, not volume.

Sources and dates
Outlet locations, waterbody links and spill figures come from the Environment Agency 2025 event duration monitoring annual return. The latest company reports come from each operator’s live feed and carry their own dates. Waterbody ID: GB530604002300. The official waterbody record is a source lookup; its classification is not imported here.
Questions about Medway
- Which outlets are linked to Medway?
- The source links 86 outlet records to waterbody GB530604002300. The link comes from the annual return; it does not model where a discharge travelled.
- How many spills were recorded for Medway?
- 86 records report 707 spills in 2025 and 1,465 recorded hours. All listed records have a usable count. Outlets can discharge at the same time, so the hours are not the time the whole water was affected.
- Who is responsible for the outlets on Medway?
- Southern Water operates every listed outlet. Contact the operator or the official pollution service if you see a problem in the water.
- Which outlets on Medway are linked to a live feed?
- 76 of the 86 records are matched to a monitor in a company live feed. A link does not mean the monitor is working now. Use the status filters above to see the latest report for each outlet, with its date. The rest show annual figures only.
- How complete is the monitoring for Medway?
- 26 of the listed records have monitor operation below 90% for 2025. Events can be missed when a monitor is not working, so low counts from those outlets may understate activity.
- Does this show if Medway is safe?
- No. Event duration data does not measure bacteria, chemicals or current water quality. Use official local water-quality advice for that question.
