The original (lower) reservoir was completed in 1863 and has a capacity of 11.3 billion litres and a maximum depth of 18.3 metres. A second embankment, 3.5 km upstream, was completed in 1923 to form the upper reservoir. This has a capacity of 5.6 billion litres and a maximum depth of 13.4 metres.[1]

The Vartry Reservoir scheme involved the partial redirection and damming of the Vartry River, the building of a series of water piping and filtering systems (and related public works) to carry freshwater to the city.[2]

Between 1862 and 1868 the lower reservoir was formed by constructing an earthen dam across the valley of the River Vartry after a Dublin Water Works Committee was established to develop a new water supply to Dublin and suburbs.[3] The committee was chaired by Dr. John Gray who actively promoted what would become the "Vartry scheme".[4] The scheme was formally opened on June 30, 1863.

This work was particularly important in the improvement of living conditions and public health in Dublin city.[4] It improved sanitation and helped reduce outbreaks of cholera, typhus and other diseases associated with contaminated water.
