1 Irish Water All of our customers should receive a safe and reliable supply of drinking water and have their wastewater collected and safely returned to the environment. We will protect the environment in all our activities and support Ireland s social and economic growth through appropriate investment in Water Services.

2 What is Greater Dublin Drainage? Greater Dublin Drainage (GDD) is the development of a new regional wastewater treatment facility and associated infrastructure to serve the population of Dublin and parts of the surrounding counties of Kildare and Meath. The project is necessary to meet Water Framework Directive (WFD) requirements and other relevant EU directives and national regulations related to water quality. Once operational from 2025, the GDD project will have the capacity to provide wastewater treatment for the equivalent of half a million people. Irish Water intends to make a planning application for the GDD project to the independent planning authority, An Bord Pleanála, in 2018.

3 Project benefits GDD is a once-in-a-generation project. It represents the next major step in the development of the wastewater infrastructure for the population of Dublin and the surrounding counties. The GDD project will treat wastewater generated every day in our homes and workplaces. The GDD project will: > safeguard public health; > protect and improve the environment; and > facilitate development, social progress and economic growth in the wider Dublin region to 2050.

4 Why do we need GDD? Projected Treatment Capacity Requirements Census 2016 recorded that Dublin and the commuter belt counties of Meath and Kildare are among the fastest growing counties in the country. Popula2on Equivalent As our population and economy grow, 0 so too does the volume of wastewater Year The amount of wastewater generated in Growth Scenario 1 - Low Growth Scenario 2 - High Growth Scenario 3 - Most Likely Installed Ringsend Treatment Capacity greater Dublin is projected to increase by over 50% in the period to The GDD project will provide the additional treatment capacity needed once the country s largest wastewater facility at Ringsend reaches its upgraded maximum capacity by the mid-2020s.

5 Existing wastewater treatment plants and catchments Wastewater generated in the Greater Dublin Area is currently treated at eight main wastewater treatment plants. Irish Water is working to upgrade all of these facilities to their full capacities. However, even with these upgrades, due to the projected increases in population and industry in Dublin and in the surrounding counties of Kildare and Meath, there is a need to develop an additional regional wastewater treatment facility to meet future demand.

12 Environmental assessment GDD will safeguard public health and protect and improve the environment. A range of environmental studies have been conducted including both land-based and marine-based surveys: Tide and Current Surveys Sediment Surveys Bird, Bat & Badger Surveys Marine Mammal Surveys Fisheries Surveys Bathymetry Survey and Sub-Bottom Profiling Underwater Noise Survey Archaeological Geophysical Survey Landside and Marine Ground Investigations Reef Habitat Survey An Environmental Impact Assessment Report (EIAR) is being prepared for the GDD project.

13 Construction Construction of the GDD wastewater treatment plant and the associated orbital sewer, pumping station and marine outfall will take approximately three years and will begin, subject to planning permission, in A construction environmental management plan will be used to mitigate and minimise potential construction impacts (noise, dust, traffic, etc.). We will liaise closely with local communities throughout construction and all works will be undertaken in a safe and environmentally responsible manner.
