Discharge Pipe

In the early 1960s a coal-fired electricity generating station was built at Cockenzie on the East Lothian coast. Environmental considerations meant novel solutions had to be found for the station waste so ash was piped as slurry along the coast to be deposited in settling ponds (confined by a seawall running westward from Prestongrange to the mouth of the River Esk). Some could be used to produce building material (breeze blocks) but the rest was sculpted, planted and developed as a coastal park.
