The Dublin section of the Grand Canal was opened on 23 April 1796, while Portobello Harbour came into use in 1801. In 1812 Richmond Basin, Portobello, (later called the "City Basin"), located between Lennox Street and the canal, was opened as a water reservoir for the south side of the city. From 1860 investigations of the water quality coming from the Basin showed that it was not up to standard – in particular, levels of sulphuric acid were relatively high. Public representatives from Rathmines were unwilling to cough up the necessary money for a new water-works, but the will of the majority prevailed, and the new Vartry Reservoir was completed in 1863.
