The new Stillorgan Covered Reservoir is now complete - ensuring a safer, more secure and sustainable water supply for over 200,000 in south Dublin.

After almost 150 years serving the community, the Stillorgan Reservoir has been modernised to adequately meet current requirements and the needs of future generations.

200,000 Dubliners to benefit from the completion of new Stillorgan Reservoir.

Planning permission for the reservoir works was granted, subject to sixteen planning conditions, by Dún Laoghaire-Rathdown County Council on the 1 June 2017. An appeal was lodged to An Bord Pleanála seeking the removal of one of the conditions which is to provide publicly accessible open space within the site. In December 2017, An Bord Pleanála approved the planning application to ensure the entire site is retained for this future development.

You can view the planning application details on the Dun Laoghaire-Rathdown County Council website.
