Stillorgan Reservoir

Tender description

Stillorgan Reservoir is a modular storage facility for treated drinking water, built in two stages between 1862 and 1885. The site has a total plan area of approximately 16 hectares and is subdivided into three discrete water storage reservoirs, the Gray, Upper and Lower Reservoirs. The Lower and 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. The planned works are necessary to ensure compliance with EU Directives, Irish National Standards and Regulations relating to treated water for human consumption. It is intended that the works will be implemented under a Design and Build Contract. The information provided herein is preliminary only and will be superseded by the Invitation to Tender (ITT).
