What is involved?

  • Construction of approximately 4.85km sewer to the Leixlip Wastewater Treatment Plant
  • Construction of a pumping station within the site boundary of the existing Leixlip Wastewater Treatment Plant
  • Construction of approximately 8km of underground mains from the wastewater treatment plant to a sewer on the Damastown Road, near Blanchardstown, Co. Dublin
  • The reinstatement of construction areas to match the original condition and associated site works

Benefits

  • Upgrade the wastewater network to facilitate existing and future development.
  • Enable long term social and economic development.
  • Ensure a resilient wastewater treatment network.

What are the next steps?

  • Irish Water recently awarded a contract to BAM Civil Limited to carry out the works as part of this project. Works are due to commence Q2 2020 and will take approximately 24 months to complete.

Frequently Asked Questions

The Greater Dublin Drainage Study (GDSDS) was completed in 2005 and comprised a strategic assessment of the existing wastewater network in Dublin (Fingal, South Dublin, Dublin City, and Dun Laoghaire-Rathdown), Meath, Kildare and Wicklow. This study identified strategic recommendations for wastewater infrastructure requirements.This project forms part of Irish Water’s investment plan to upgrade wastewater services in the area.

Irish Water has identified that an upgrade to the existing wastewater network is required in the Greater Dublin Area to facilitate existing and future development and to ensure a resilient wastewater network.

While the majority of the proposed route is through agricultural land, it will be necessary to carry out some works within St. Catherine’s Park and Littlepace Park. It is planned that works will commence in Q2 2020 and will take approximately 24 months to complete.

The works will be carried out by BAM Civil Limited on behalf of Irish Water. All works will be overseen by Irish Water.

Access to St. Catherine’s Park and Littlepace Park will be maintained throughout the duration of the construction works; however access to working areas will be restricted to ensure the safety of staff and park users alike. Reinstatement will take place as the pipeline is installed to minimise impact on both parks.

Signage will also be provided to advise users of any pedestrian access routes which may be closed temporarily and diverted. The working areas have been developed to minimise the footprint of any construction work in the parks and in order to maintain access to the parks.

As part of this project an Ecological Clerk of Works will be on site. Planting of native tree species will replace those removed and amenity grasslands will be reseeded. To facilitate construction, in St Catherine’s park, 19 trees are to be removed and replaced with 27 Lime Trees (‘Tilia Greenspire’) while in Littlepace Park there will be 8 trees removed and replaced with 8 Lime Trees (‘Tilia Greenspire’) as part of the project.

Disturbance to species will be minimised by restricting works and construction related activity to within the working areas and access routes. Trees, hedgerows and scrub will be inspected for the presence of nesting birds and will be overseen by the Ecological Clerk of Works.

To minimise disruption, heavy construction equipment/machinery will only be operated during the following hours:

  • Normal working hours will be Monday to Friday 8.00am to 7.00pm.
  • No operation on Sundays or Bank Holidays.
  • Night or weekend work is not permitted without express approval of Irish Water.
  • Access and egress for construction traffic to Littlepace Park is not permitted during school drop off and pick up times for the Mary Mother of Hope Junior and Senior National School in Littlepace between the hours 8.30am to 9.30am, 12 to 1pm and 2 to 3pm.

In order to minimise the generation of dust the Project Team will undertake the following:

  • Spraying of exposed earthworks activities and site haul roads during dry weather.
  • Covering of skips and soil heaps.
  • Provision of wheel washes facilitates.
  • Control of vehicle speeds, speed restrictions and vehicle access.
  • Sweeping of hard surface roads

In order to minimise the generation of noise the Project Team will ensure the following measures are in place:

  • All construction plant and equipment shall comply with Statutory Instrument No. 359 of 1996 “European Communities (Construction Plant and Equipment) (Permissible Noise Levels) regulations 1996”;
  • Silencers and engine covers will be kept in good working order;
  • Construction Plant machinery will be turned off when not in use.

To prevent any potential odour issues, the proposed pumping station at Leixlip Wastewater Treatment Plant will include odour control and a ventilation system. The proposed pipelines will not generate odour during construction or normal working conditions.

The Project Team will notify the local community in advance of works commencing and will provide contact details should they have any questions regarding the works. As part of this project BAM Civil Ltd have a full time Community Liaison Officer who will communicate with all stakeholders as the project progresses and will be available to address any queries or concerns in relation to the works.

The working areas have been developed to minimise the footprint of construction work in the parks and in to maintain access to the parks. Following the completion of works, St. Catherine’s Park and Littlepace Park will be reinstated to their previous state.
