Questions about South West Water

What do the South West Water figures cover?
This page totals 1,357 outlet records with a usable 2025 spill count, out of 1,365 records in the England dataset. Missing values are not counted as zero.
How many South West Water outlets are linked to a live feed?
1,340 records are matched to a monitor in the company live feed. A link does not mean the monitor is working now. Use the status filters above to see the latest report and its date. 25 records have annual figures only.
How many South West Water outlets recorded zero spills in 2025?
178 records report zero counted spills. 45 records have monitor operation below 90%, so a zero from one of those outlets may not cover the whole year.
Does a recorded spill show how much sewage was discharged?
No. Event duration monitors report when an overflow operated. They do not measure the volume released or the water quality.
Can I compare South West Water with another company?
Take care. 45 records have monitor operation below 90%, and companies differ in outlet numbers and area. Check missing values and monitor coverage before making a comparison.
How do I report pollution from a South West Water outlet?
Use the official pollution reporting route in our guide. Give the outlet name, permit reference and the time you saw the problem. Sewage Map does not send incident reports.
