Davyhulme Wharf and Disused Sludge Hoppers

Treated sludge from Davyhulme Sewage Works was loaded into ships and discharged into the Mersey estuary from 1898. Over the next hundred years, seven ships were used to transport the sludge, including one borrowed from Glasgow after another hit a mine and sank. At first, ships used the ship canal to transport sludge from the works, but later a pipeline was built to Liverpool, and the ships made a much shorter journey. (Wikipedia)
