Bury New Rd Lockett St CSO
Sign in to saveStorm overflow run by United Utilities, discharging into The River Irwell.
"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: our own log of it begins on 28 February, and the discharges before that are Top of the Poops' record of the same feed. The feed reports only each overflow's latest discharge, so a discharge it moved past before we saw it end is counted as one spill with no hours: the hours are a floor. 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.
2020 was the first year every company reported for all its monitored overflows, with monitors still being installed through the year: a 2020 figure covers the share of the year the monitor was working, shown beside it, and an overflow with no 2020 bar had no return that year.
Other outlets here
United Utilities runs 3 other overflows within 300 m that also discharge into The River Irwell. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.
This overflow (Bury New Road/Lockett Street CSO): 5 spills in 2025. Distances are between the published outlet points. The names in brackets are United Utilities's own, from its return.
What the 2025 return says
From United Utilities'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
22 discharge periods since 22 Feb 2024, 1 whose end the feed never gave. 19 of them come from United Utilities's own event-duration-monitoring records (published on Stream, Feb 2024 – Oct 2025); 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 37 raw blocks were merged into 22 continuous discharge periods (gaps under 15 min joined).
Look back by date
Discharge records held: 1 Jan 2023 to 31 Dec 2025. Choose the dates of a flood or a storm to see every discharge recorded then.
Days run midnight to midnight, UK time, up to 366 days at a time. A discharge beside rain or a flood is a timing match, not proof of cause, and no volume is published.
Rain nearby last 30 days
Nearest live rain gauge: Rainfall gauge nr Prestwich, 5.0 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).
