Eastbourne WwTW
Storm overflow run by Southern Water, discharging into The English Channel.
Linked bathing waters: Eastbourne, classified Good for 2025; Pevensey Bay, classified Good for 2025. Named in the company’s return to the Environment Agency. A name opens that bathing water’s official profile, with any pollution warning in the season. The classification is the Environment Agency’s for that bathing season, from all its samples there: it is not a reading of the water today, and it does not say what part this overflow played.
"Not discharging" means the company's monitor reports no discharge right now — not that the water is clean. The feed publishes status only; no discharge volume is measured.
Year by year
The Environment Agency's official annual returns, counted the EA's way (12/24-hour spills). 2026 is our own running count, the same way, from Southern Water's monitor log. The official figure is published next spring.
A spill is the EA's 12/24-hour count: the first 12 hours of a discharge count as one, each further 24 hours with discharge as one more. "Monitor" is the share of that year the monitor was working, so a 0 beside a working monitor is a real zero; "no data" means the monitor produced no usable data that year — not zero. Years before 2024 are matched to this site by name and location, because the EA's site IDs changed that year; a monitor figure beside one of them means the outlet's permit confirms the match.
Other outlets here
Southern Water runs 2 other overflows within 300 m that also discharge into The English Channel. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.
This overflow (Eastbourne No.2 CEO - 115459): 5 spills in 2025. Distances are between the published outlet points. The names in brackets are Southern Water's own, from its return.
What the 2025 return says
From Southern Water's annual return to the Environment Agency for this overflow.
"High spill threshold not met" means this overflow did not spill often enough to trigger the EA's formal high-spill review for that year. It is not a statement that the spills were harmless.
Discharges we have recorded
69 discharge periods since 28 Jan 2021. 68 of them come from Southern Water's own event-duration-monitoring records (from its Rivers and Seas Watch service, Jan 2021 – Aug 2026); this overflow has no live feed, so nothing after that log is held. The official annual count is the figure to quote.

The year figures above use the EA's 12/24-hour counting method, so they are comparable with the official figures; the monitor log's 135 raw blocks were merged into 69 continuous discharge periods (gaps under 15 min joined).

Nearest live rain gauge: Rainfall gauge nr Pevensey Bay, 4.0 km away. Brown shading = when this overflow was discharging; ▼ = a discharge start.
Overflow shading is a timing match, not proof of cause — heavy rain and spills share a trigger. Times come from the water company’s event-duration monitor (site status only; no discharge volume is published).
