Who is fixing it

Reduction tracker

Is each overflow actually spilling less? The reduction plan won't tell you per overflow — so we measure it from the spill record.

What the plan is, and what it leaves out

The Storm Overflows Discharge Reduction Plan is the government's plan — published in 2022 and expanded in September 2023 — to cut how often England's storm overflows discharge. It sets deadlines by category, not by overflow:

By 2035 — overflows near every designated bathing water, and 75% of those near high-priority nature sites, must be improved.
By 2045 — the remaining high-priority overflows.
By 2050 — every storm overflow, with discharges capped at around 10 spills a year regardless of location.

The targets are due to be reviewed in 2027 — a commitment in the plan, not a statutory duty. But the plan sets no target for any individual overflow and publishes no per-overflow progress — only these whole-category deadlines, and it doesn't even publish which specific overflows are high-priority. So there is no official way to ask “is this overflow on track?” This page builds that view from the Environment Agency's EDM record: each overflow's counted spills per year — the EA's own 12/24-hour block figure, the same basis the cap is written in — against its 2020 baseline and the 2050 cap of ~10, with the deadline its location implies.

What this is — and what it is not

This is River Hub's measurement, not the plan's. The reduction plan publishes no target for an individual overflow and no per-overflow progress — so we compare each outlet's counted spills to its 2020 baseline and the 10/year cap. Counted spills use the Environment Agency's 12/24-hour block method — the figure the cap is actually written in — taken from the published annual return where we have it and computed the same way for the current year; the smaller “events” figure beneath each is River Hub's count of discrete discharges over 15 minutes, shown for context. The deadline shown is derived by proximity to a designated site, not an official determination, and the plan is a policy commitment rather than a statutory duty. A falling trend is progress, but only ≤10 by the deadline is compliance. Where 2020 data is thin the baseline falls back to the earliest year on record, shown beside it. How the two counts differ →
