Irish Water is denying reports it is putting a roof on a Dublin reservoir amid fears of a terrorist attack.

The utility says the Stillorgan facility is only one of two treated water reservoirs in Ireland that is not yet covered.

A spokesperson for Irish Water says the facility serves 200,000 people and it is working to upgrade the reservoir.

A public consultation on the plans is opening today.

The Irish Independent claims the utility is upgrading the reservoir amid concerns drinking water could be at risk "from terrorists, wildlife, or vandalism."

While Irish Water says in a statement: "It is standard practice across Europe to have reservoirs with treated water covered as any contaminants can get into the water including debris, animal excrement etc."

A new covered reservoir is to be built at the existing site in advance of submitting a planning application to Dún Laoghaire-Rathdown County Council.

The Stillorgan Reservoir has supplied drinking water to the community for 150 years.

"Plans are underway to improve this facility in order to make the drinking water safer and more secure," Irish Water says.

It is now inviting the local community and interested stakeholders to have their say.

Submissions can be made to Irish Water by Wednesday, September 14th as follows:

  • E-mail:
  • Post: FAO Stillorgan Reservoir Project, Colvill House, 24-26 Talbot Street, Dublin 1
  • Telephone: LoCall 1890 815 661 (9am-5pm Mon-Fri)

Subject to planning permission, it is thought that construction will commence in 2018 and last approximately two years.
