The Haweswater Aqueduct is a major feat of engineering. The pipeline, built between 1933 and 1955, has successfully served 2.5 million people in Cumbria, Lancashire and Greater Manchester for sixty years.
In 2005 we began preparations to carry out inspections of the 109km pipeline knowing it wouldn’t be an easy task.
While they were looking around our engineers identified areas of concern that posed a potential future risk to both water quality and supply. We took action straightaway to carry out maintenance work to the worst affected areas but it was clear that more work was needed.
Independently verified research has clearly indicated that the preferred solution for customers and stakeholders is the replacement of all six tunnel sections along the length of the aqueduct. Investigations along the pipeline began in February 2019 and will continue next year. We will be putting our plans out for public consultation in Spring 2020 and expect to begin construction on the Haweswater Aqueduct Resilience Programme (HARP) in 2023.
