The Manchester Ship Canal joins the Mersey estuary here, and the town is also the northern terminus of the Shropshire Union Canal (which used to exchange goods with sea going boats at what is now the boat museum).

The town is primarily industrial, being dominated by a Shell oil refinery and an ICI chemical works.
