Ireland - Services


Water Abstraction, Treatment & Distribution

RPS has over 50 years’ experience of planning, designing and supervising the development of national water infrastructure for major cities and towns. Our integrated ‘source to tap’ approach delivers projects from strategic planning to customer delivery.

We provide planning, engineering and environmental assessment for source selection, abstraction, treatment, distribution networks, storage, water conservation, demand management and rehabilitation of underground and above ground assets.

Our multidisciplinary teams of planners, project managers, modellers, hydrologists, hydrogeologists, ecologists, process designers, civil, hydraulic, mechanical and electrical engineers deliver complex projects from feasibility assessment and planning through to construction, commissioning and operation.

Our asset management and network experts develop comprehensive asset management plans, focused on optimising the whole-life performance of existing and new assets to serve the needs of current and future generations.

Case Studies

Ballymore Eustace Water Treatment Plant



The Ballymore Eustace Plant is Ireland's largest water treatment plant. The facility serves Dublin, Kildare, Dún-Laoghaire and South Dublin with more than 300 million litres of water daily (Ml/d).

The plant has a 400 Ml/d capacity and is the culmination of a 30 year plan designed to provide the greater Dublin region with a state of the art, cost effective water supply. The plant is not only capable of meeting the current demands, it also provides for the needs of the region for the medium term until a longer term new source is developed post 2020.

There has been a treatment plant at Ballymore Eustace since the 1940's, which was expanded six times up until the 1980's, but the developments were not integrated. Therefore, RPS was engaged to assist in long term masterplanning and delivery of a modern integrated facility. RPS has been providing planning, design and engineering services on this project since the 1980’s.

Our approach in relation to the planning, implementation and design had to be highly innovative due to the environmentally sensitive location of the plant and the need to maintain an uninterrupted water supply to the city. Our solution was to rebuild the plant on a phased basis – shutting down the old facilities in a staged process as the new elements came online.

The plant combines the robust engineering required of a national strategic asset with innovative value engineering approaches resulting in real whole life cost value for the current utility provider, Irish Water.

Ballymore Eustace Water Treatment Plant was awarded the 2015 Excellence Award in Civil Engineering by the Association of Consulting Engineers of Ireland (ACEI).

Watermains Rehabilitation Projects – Dublin & Galway



Watermains rehabilitation projects are a key element of the ongoing strategy to conserve water and improve service to customers across Ireland. Our integrated team of planners, project managers, water engineers and asset management experts deliver these projects from feasibility through construction.

The Dublin Region Watermains Rehabilitation Project was the largest rehabilitation project undertaken in Ireland and involved mains renewal in combination with pressure management and the management of customer side leakage in order to achieve the maximum overall water savings. 155km of watermain has already been rehabilitated, primarily by trenchless techniques across seven local authorities. As well as design and project management services, RPS also provided risk management, health and safety (PSDP role), GIS and project communications.

The Galway City Watermains Rehabilitation Project is part of the larger Galway City Water Conservation project. It involves the replacement of approximately 20km of existing, defective watermains (including cast iron, asbestos cement and UPVC mains) with modern polyethylene and ductile iron mains at locations throughout Galway City. RPS acted as designer and PSDP up to construction stage and is currently undertaking Employer’s Representative and construction supervisions roles on this major rehabilitation project. We have undertaken environmental, appropriate assessment and invasive alien species surveys as part of the planning phase of the project. We have also developed and will assist with implementing a comprehensive communications strategy throughout the project lifecycle.
