Construction work for water projects
Stillorgan Reservoir is a modular storage facility for treated drinking water, built in two stages between 1862 & 1885. The site has a total plan area of approximately 16 hectares & is subdivided into three discrete water storage reservoirs, the Gray, Upper & Lower Reservoirs. The Lower & Upper reservoirs were constructed first, as part of the Vartry Water Supply Scheme. The Gray Reservoir was built in 1885 following a period of severe water shortage in Dublin City. The reservoirs originally contained water from the Vartry Supply Scheme alone; however, following construction of the Liffey Supply Scheme at Ballymore Eustace in the 1940s, a 24” main was laid between Saggart Reservoir and Stillorgan Reservoir to link the two supplies. An additional 1000mm diameter trunk main linking the supplies was constructed on a phased basis during the 1990s.
