Warleigh Weir, a location along the River Avon near Bath, is visited by people who use the stretch of river for recreation, including swimming.
We have been working with the landowner, the Rivers Trust, Bristol Avon Rivers Trust and the Environment Agency to discuss river water quality at the location, which can be affected by a number of factors – from our storm overflows and treated wastewater from our water recycling centres being returned to the river upstream to agricultural run-off, septic tanks, road drains and wild animals.
In September 2020 intensive water quality monitoring took place, involving a partnership with The Rivers Trust with Bristol Avon Rivers Trust, Wessex Water, Sewage Free Swimmers and the Environment Agency, and a team of volunteers.
To understand more about water quality at this location, investigative work is underway to find out more about the factors in the large river catchment upstream of the site which influence the condition of the river water and the role our assets have.
Monitoring storm overflows
Storm overflows act as relief valves, allowing excess stormwater to be released to rivers or the sea. This protects properties from flooding and prevents sewage backing up into streets and homes during heavy storm events.
We monitor when storm overflows are in use that affect bathing waters and information is provided on Coastwatch. This now includes information on when our storm overflows operate which affect some inland waters, including Warleigh Weir. You can find out the location of storm overflows and how often they are in use on our online mapping system.
We have extended our notification system which now includes when the following sites are in use, which are upstream from Warleigh Weir:
- Culver Street, Bradford on Avon
- Monkton Combe, Mill Lane
- Freshford Water Recycling Centre (formerly known as sewage treatment works)
This information is sent to the landowner and anyone can use either our Coastwatch system or the Surfers Against Sewage SaferSeas (and Rivers) app to find out when they have operated. The SaferSeas app also allows you to register for live information on these overflows.
