Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, how many instances of water quality breaches have been reported by water suppliers in Lancashire in the last 12 months.
Answered by
Emma Hardy
Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The Drinking Water Inspectorate does not compile water quality breach data by county. The figures provided relate to United Utilities' operations across its entire supply area, which serves Lancashire and the wider Northwest region.
In the 12-month period from Q4 2024 to August 2025, there were 107 water quality breaches reported by United Utilities, which is the water supplier serving Lancashire.
This data is reported as of 24 October 2025 and is subject to change as new data is reported. These figures are not yet final, as water companies have one month following a breach to investigate the cause and rectify any issues before completing their compliance reports. Data for September and October 2025 is not yet available.
