Elan aqueduct

The Elan aqueduct is a water transportation system extending from the Elan Valley Reservoirs in Wales to Birmingham's Frankley Reservoir, crossing eleven major river valleys. The system uses natural gravity and flowing water rather than mechanical pumps to move water across the distance.

The first section was built in June 1896 by the Birmingham Corporation Water Department to address water shortages during industrial growth. The project developed into one of Europe's largest water transportation systems of that era.

The infrastructure shows Victorian engineering skill through its combination of underground tunnels, bridges, and inspection chambers spread across the land. Visitors can experience this blend of technical structures and natural landscape today along various sections.

Most sections run underground or are not easily accessible from roads, so visitors should research which points are open beforehand. The best time to explore is during months with mild weather when footpaths are in good condition.

Some sections extend over 330 feet (100 meters) deep below ground and require specialized access points visited by engineers and enthusiasts. These hidden parts reveal the complexity of the construction and remain unknown to most visitors.
