City Centre Sewerage Scheme

Feasibility Study

The City Centre Drainage Area Catchment stretches from the Royal Canal in the north to the Grand Canal in the south and from Chapelizod in the west to the Dublin Custom House in the east. A separate drainage area plan has been developed for the docklands part of the catchment. In the last 10 years the area has undergone substantial development and this has put pressure on the drainage system in the catchment.

The City Centre Sewerage Scheme is a follow-on project from the Greater Dublin Strategic Drainage Study (GDSDS). The aim of the project is to develop on the GDSDS findings and identify areas of the catchment that are under capacity and to propose solutions.

DCC is currently in the preliminary planning stage of this project.

Phase 2(Surface Water Separation)

Phase 2 is the implementation of schemes, in advance of the main scheme, that can remove stormwater from the combined City Centre Interceptor Sewers.
The aim of the scheme is to divert the surface water flow from the Phoenix Park, that currently flows into the north city centre interceptor sewer, so that it flows directly into the River Liffey at the Parkgate Street weir, discharging at the outfall west of Sean Heuston Bridge. In addition, the storm water network in Montpelier can also be diverted to the Liffey due to its proximity.
