One of the best kept
secrets of the heart of Wales is the Elan Valley. In the 19th Century this
whole valley system was bought by Birmingham, my home town, and a series of
dams built to create the reservoirs that supply the city with its water. The
system is one of the world's largest gravity fed systems - the water leaves
the Elan valley and makes its way to Birmingham, 80 miles away through an
aqueduct/tunnel, arriving at the Bartley Reservoir near where I work in
south west Birmingham. |
