Storm overflow run by South West Water, discharging into River Dart.

Inlet storm overflow at sewage treatment works Bathing water Central Devon constituency

Linked bathing water: Steamer Quay, Dart Estuary, classified Poor 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 South West Water's monitor log and the live feed. 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.

Twin outlet

South West Water runs another overflow within 300 m that also discharges into River Dart. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.

This overflow (KILBURY STW_SO_BUCKFASTLEIGH): 93 spills in 2025. Distances are between the published outlet points. The names in brackets are South West Water's own, from its return.

Downstream of this overflow

This overflow is beside the Austins Bridge gauge, too close along the river to say whether it is above or below. The next gauge further downstream that the river map places is Totnes (Tide), 12.0 km along the river.

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.

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

294 discharge periods since 1 Jan 2025, 1 still open. 282 of them come from South West Water's own event-duration-monitoring records (published on Stream, Jan 2025 – May 2026); 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 1,119 raw blocks were merged into 294 continuous discharge periods (gaps under 15 min joined).

What the feed showed

FloodRadar's own record of every change of state South West Water's live feed has shown for this overflow, kept since : 8 states. The feed publishes its status now and its latest discharge, nothing older; the discharges above are read from this. It is here so the figures can be checked.

Nearest live rain gauge: Rainfall gauge nr South Hams, 0.1 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).

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 Central Devon 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.
