The GDD project team are managing the planning stages of the project which involves the preparation of a planning application, including an Environmental Impact Statement (EIS), to be submitted to An Bord Pleanála towards the end of 2016.

Over the coming months several marine environmental surveys will be undertaken in Baldoyle Bay, between Portmarnock and north of Ireland’s Eye, to determine the condition of the sea bed, what marine life exists and to establish tide and current patterns.  These surveys are necessary to inform the Environmental Impact Statement (EIS) and proposed construction methodology for the outfall, i.e. the pipe that will discharge the treated wastewater to sea.

We will communicate with water based business and leisure organisations in Portmarnock, Baldoyle and Howth through information events, further e-zines, the project website, and via local media in the Spring when we have more details.

We met many members of the public and public representatives at our series of information pop-up events during the past year and we look forward to meeting you at more such events in the coming year.

We wish you a happy Christmas and look forward to engaging with you in 2015.

Foreshore Licence Public Consultation Now Underway

Marine Ground Investigations (GI) are required in Baldoyle Bay, to confirm what the bedrock is like, i.e. the condition and make-up of the rock underneath the seabed, so that the project team can make informed decisions regarding suitable construction methodologies for the outfall pipe. The investigations should be completed over six months, depending on the weather.

A Foreshore Licence is required from the Department of Environment, Community & Local Government for the project team to undertake these Marine GI studies. The application (reference FS006292) and associated maps, reports and plans are available to view and make submissions from Thursday 11th December 2014 to Tuesday 20th January 2015 at the following locations:

Submissions can be made directly to the Department of Environment, Community & Local Government – see details in the attached Public Notice.

Land Based Surveys

The marine surveys are being complemented with land surveys at the proposed Wastewater Treatment Plant in Clonshagh (Clonshaugh) and along the route of the proposed pipeline, again to inform the planning application and proposed construction methodology.  We thank landowners for their co-operation and assistance in facilitating these studies.
