Plans Submitted To Develop New Reservoir In South Dublin

A planning application has been submitted to develop a new covered reservoir in south Dublin.

Irish Water put forward the application to Rathdown County Council for permission to build the reservoir at the Stillorgan Reservoir site.

The new covered reservoir is essential to safeguard the quality of the drinking water for over 200,000 customers. The existing Stillorgan site contains three open water reservoirs which store treated drinking water prior to its distribution to customers.

The Stillorgan Reservoir Upgrade Project includes the draining of one of the reservoirs and the construction of a new covered reservoir. Once the new covered reservoir is operational, the other two open reservoirs will be decommissioned and landscaping of the site will take place. The new covered reservoir will have the capacity to support future growth to 2031. The locations of the decommissioned reservoirs will be maintained for future water services infrastructure to secure the long-term supply of drinking water for the community.


Geoff O'Sullivan, Project Manager with Irish Water, said: "Covering the reservoir will safeguard the quality of drinking water for the community and provide a long-term solution for the safe and sustainable management of the water supply for the next 15 years. This is a priority project for Irish Water and we are committed to investing approximately €80 million to ensure the upgrade to the reservoir provides the long term solution that is required to secure the water supply."
