The plan for the canal was completed in 1815 and the [[act of Parliament (UK)|act of Parliament]], the '''{{visible anchor|Portsmouth and Arundel Navigation Act 1817}}''' ([[57 Geo. 3]]. c. lxiii), passed in 1817.<ref name=TC_PLC9 /> At this stage costs were estimated at £119,000 rising to £125,452 in 1818.<ref name=TC_PLC /> Construction started in 1818 and the canal was finished in 1823, at a cost of £170,000. The resident engineer was [[James Hollinsworth]] who was paid £500 per annum.<ref name=green12 />

To supply the canal with water a pumping engine was installed at Ford to pump water from the Arun.<ref name=green18 /> 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.<ref name=green18 /> This was to prevent salt water from entering the canal.<ref name=green18 /> 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.<ref name=TC_PLC />
