Waterloo Road Kington Overflow
Storm overflow run by Dwr Cymru Welsh Water, discharging into River Arrow.
"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 the live feed since 23 September (when we began keeping every discharge it reports) — so it can only be lower than the full year. 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.
Downstream of this overflow
The next gauge downstream that the river map places is Titley Mill (River Arrow), 3.6 km along the river.
Water-sampling points downstream
The nearest Environment Agency sampling points the river map places below Titley Mill. Points between this overflow and that gauge cannot be put in order with it on the map, so they are not listed.
- River Arrow at Mowley
6.5 km along the river, below Titley Mill · Last sampled 17 Dec 2025 · 10 months ago - Arrow downstream of Arrow Green
21 km along the river · Last sampled 2 Jun 2023, before the imported period - Lugg Marden
52 km along the river · Last sampled 30 Jul 2026 · 2 months ago
A sample is dated: it is not the river now, and its results are on its own page. A sample taken after a discharge does not show that the discharge caused what was measured.

A river gauge measures the level of the river; it does not measure this overflow's discharge, and a spill does not by itself explain a change there. Traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.

What the 2025 return says
From Dwr Cymru Welsh Water's annual return to the Environment Agency for this overflow.
This overflow spilled often enough to trigger the EA's high-spill review; the review line is the company's own stated reason.
Discharges we have recorded
528 discharge periods since 8 Jan 2020, 1 still open. 526 of them come from Dwr Cymru Welsh Water's own event-duration-monitoring records (published on Stream, Jan 2020 – Dec 2025); the live feed adds anything after that. 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 842 raw blocks were merged into 528 continuous discharge periods (gaps under 15 min joined).
Rain nearby last 30 days
Nearest live rain gauge: Rainfall gauge nr Titley, 2.8 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).
Where it is
Tell me when this overflow discharges
One message when the company's monitor reports a new discharge here. At most one every 6 hours.
Setting this alert needs JavaScript. The alerts you already have are on your alerts page.
The alert repeats the monitor's status: whether the overflow is discharging, not how much or why. It can only tell you about a discharge that starts after you turn it on.
Concerned about this overflow?
Report pollution you can see or smell to the regulator straight away; the company handles complaints about the overflow itself.
Write to the MP
The Environment Agency's return places this overflow in the North Herefordshire constituency. An MP can ask the company and the regulator questions on a constituent's behalf. These words carry the official figures; change them as you like.
The link opens Parliament's own "Find your MP", which gives the MP's name and how to write to them. FloodRadar sends nothing and keeps nothing you write. Check the constituency against your own address: an MP acts only for people who live in it.
