To supply the canal with water a pumping engine was installed at Ford to pump water from the Arun. Since the Arun is tidal at Ford the act of Parliament only allowed water to be taken from the river between two hours after high water and one hour after low. This was to prevent salt water from entering the canal. In order to allow the passage of masted ships iron swing bridges were fitted to the Chichester and Portsea sections rather than the more typical hump back canal bridge.
