Late C18 staircase of sandstone weirs built in steps below the Swansea Canal in order to take surplus water from the canal to the River Tawe after periods of rain and during periods of canal drainage. The surplus canal water from the overflow and outlet was used in C19 for power for the Pheasant Bush tinplate works.
