Manchester’s water supply from the Lake District is a significant and historic system that has been in place for over a century. The primary reason for Manchester to seek water supply from the Lake District was the rapid growth of its cotton industry in the 19th century, which placed an increasing demand on water supplies. The city needed a reliable and pure source of water to support its industrial and residential needs.
The Thirlmere Aqueduct: Delivering Water to Manchester
The water from Thirlmere reservoir reaches Manchester through a 96-mile-long aqueduct, which was built between 1890 and 1925. This pioneering section of the water supply system was constructed by the Manchester Corporation Water Works. The aqueduct carries approximately 55,000,000 imperial gallons (250,000 m3) of water per day from Thirlmere to Manchester, passing through Lancashire and entering Manchester through Salford.
Thirlmere Reservoir: A Pure Water Source
Thirlmere reservoir is one of the purest water sources in the country due to its glacial valley location, which provides good water catchment fells on either side and streams running down into the valley bottom. The reservoir is filled entirely by rainwater, and the surrounding coniferous and deciduous woodlands contribute to soil stability, reducing soil erosion into the reservoir.
Maintaining the Water Supply System
Haweswater Aqueduct Resilience Programme (HARP)
United Utilities is currently undertaking a major scheme to maintain drinking water supplies across Cumbria, Lancashire, and Manchester. The project involves replacing six tunnel sections along the pipeline route and is expected to start major construction activities in 2025.
Water Management
United Utilities manages the reservoir and the surrounding 12,000 hectares of land, ensuring the protection of the reservoir from pollution sources and maintaining the wildlife in the area.
Tap Water Quality
Tap water in the Lake District, including Manchester, is drinkable and of high quality, sourced from local springs and reservoirs.
