Irish Water wants to spend around €50 million upgrading the sewers in Blanchardstown, Meath and Kildare
The proposed project will be located along the Tolka River Valley in Blanchardstown.

IRISH WATER SAYS it is submitting a planning application to Fingal County Council to upgrade the existing sewer network serving Blanchardstown and surrounding areas.

The €50 million plan will also see the networks improved in Kildare and in Mulhuddart and Castleknock in Dublin and Dunboyne, Clonee, Ashbourne and Ratoath in County Meath.

The proposed project will be located along the Tolka River Valley in Blanchardstown between Parslickstown and Mill Road and a new pumping station will be constructed at Waterville close to Mill Road.

The project will include the construction of around 3.2kms of new sewer pipelines using trenchless tunnelling techniques and the construction of underground storage tanks with a total combined capacity of approximately 30,000m³. A new control building to house all electrical switchgear, control equipment, an odour control unit, a generator room and ESB sub-station.

During the project local sewer and utility diversions will be carried out to facilitate construction of the storm water storage tanks and Tolka Valley Park Pumping Station.

Once the proposed project is complete the area will be fully reinstated to match the original condition and associated site works. The existing sewer network was originally constructed in the Tolka Valley in the 1970s to serve Blanchardstown, Mulhuddart and Castleknock.

The existing sewer network does not have the capacity to serve the needs of this fast growing population and is subject to flows which results in untreated wastewater overflows from the sewer network to the River Tolka.

Commenting on the project Paul Fallon, Wastewater Infrastructure Manager at Irish Water said:

“Irish Water is pleased to be progressing this important project for Blanchardstown and the surrounding areas in Meath and Kildare. The proposed project will expand the existing capacity of the wastewater network in the area to facilitate existing and future residential and commercial growth.”
