Barrow Water Supply Scheme Area Extension

Water Supply Scheme

Uisce Éireann is progressing works to increase the security and resilience of the drinking water supply for Kildare and the Greater Dublin Area.

Uisce Éireann, working in partnership with Kildare County Council and Dublin City Council, is progressing the commissioning the Barrow Water Supply Scheme Area Extension project. This project has extended the water supply from Srowland Water Treatment Plant in Co. Kildare and facilitated a strategic link with Ballymore Eustace Water Treatment Plant. David Walsh Civil Engineering is working on behalf of Uisce Éireann to deliver this project.

With the demand for water increasing, it is essential that water resilience projects are progressed to ensure that there is an adequate supply of treated water for now and into the future, to support population growth and social and economic development. This vital project has increased the security and resilience of the drinking water supply for Kildare and the wider Greater Dublin Area (GDA).

In Progress

What are the benefits of this project?

The works carried out as part of this project will:

  • Support future growth and development in Naas and the surrounding area.
  • Decrease the dependence of Kildare on the River Liffey water supply.
  • Increase the resilience of the drinking water supply to businesses and residents in the Greater Dublin Area (GDA).
  • Result in an increase in supply of up to 18 million litres per day (Mld) of drinking water for homes and businesses to the GDA. This is equivalent to enough water for almost 140,000 people.

What was involved as part of this project?

As part of this project, Uisce Éireann has:

  • Constructed 3km of water main between Killashee and Naas via the Rathasker Road.
  • Constructed two new booster pump stations at Brannockstown and Carnalway to facilitate the transfer of water from the Old Kilcullen reservoir towards Ballymore Eustace Water Treatment Plant.
  • Upgraded the pipework connections, controls and telemetry at Ballymore Eustace Water Treatment Plant and Old Kilcullen Reservoir.

Why do we need to increase our water supply?

  • Demand for water across the country and in the GDA has been increasing steadily. The recent water conservation orders (hosepipe ban) illustrate the current pressures on water resources due to drought and increased water demand.
  • As water supply is essential for public health, Uisce Éireann must ensure appropriate levels of supply are provided to endure drought conditions, peak events and maintenance of our network.
  • This project will maximise the available supply from Srowland WTP and provide up to an additional 18Mld to the wider region. This plan to provide greater supply capacity to Kildare was originally proposed the 2003 Kildare Water Strategy.

What is happening now?

Commissioning works are currently underway. During the works, every effort will be made to maintain water supplies to consumers, however some temporary discolouration of water may be encountered.
