How many times did Lower Somerton spill in 2025?
The 2025 return records 15 counted spill events and 165.8 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 99.9% of the reporting period, so the annual figures cover most of the year. They still do not measure discharge volume.
Is Lower Somerton discharging right now?
This record is not matched to a company live feed, so we cannot show a current report. Only the annual figures are available for this outlet.
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 Lower Somerton?
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 Lower Somerton compare with other overflows?

Among Wessex Water overflows it ranks 553rd of 1,332; the median Wessex Water overflow recorded 11 spills. On the Cary - source to conf with KSD waterbody it ranks 8th of 9.

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.
