Saggart Reservoir Project

featured projects 526 x 350

The Saggart Reservoir Project involves constructing a new covered treated storage reservoir that will safeguard the water supply to homes, essential services and businesses in the Greater Dublin Area. The upgrade marks the first significant investment in the existing Saggart waterworks since it was built in the 1950s. This new, state-of-the-art reservoir will house over 100 million litres of treated drinking water or the equivalent of 40 Olympic-sized swimming pools, supplied from the Ballymore Eustace treatment plant (Ireland’s largest water treatment plant). The scheme also includes a new electro chlorination plant building and associated infrastructure. This project will provide strategic treated water storage capability at Saggart, South County Dublin, which is needed to support the construction of houses and schools, attract new industry, and allow companies to expand and grow across the GDA (Greater Dublin Area). In terms of size and scale, the new reservoir can store enough water to supply almost 300,000 homes for one day.

Our Role

Coffey Construction has engaged ByrneLooby to provide detailed civil, structural, geotechnical and hydraulic design as well as PSDP services. 

ByrneLooby will support Coffey Construction in delivering this essential infrastructure with the construction of the new reservoir and associate pipelines commencing in March 2021 and a completion date expected in 2024.

Challenges: Increasing demands in the Greater Dublin Area is a challenge for the national utility Irish Water’s long-term water supply solution. Some 600 ML/day of treated water currently produced in the GDA Water Network meets current demand levels to supply approximately 1.5 million customers in Dublin and the surrounding areas. However, there is limited headroom capacity available - only c. 3% (c.18ML/d). At times of water stress, especially during periods of drought, this capacity is under more strain. Saggart is part of the long-term water supply and delivery plan that includes leakage reduction in the region and transferring spare capacity from Athy to Greater Dublin.

The benefits of this scheme include increased security of supply and greater network resilience of the drinking water supply to businesses and residents in the Greater Dublin Area, which will enhance future growth and development in the region.

Sustainability Initiatives


Public Realm
Sensitive receptors are a key challenge on the Saggart Reservoir project. The majority of local residents are located close to construction works on the site's northern edge. Regular working hours have been reduced, and the monitoring of noise, dust, vibration, and odour has been increased. Site lighting has been relocated to reduce the impact on local residents. A comprehensive one-way traffic management system was introduced onto Castle Street to avoid delay and disruption to residents as reasonably practicable.

Carbon reduction
In advance of the compound setup in Saggart the lighting and office layout were pre-planned to orientate the offices for optimum solar gain and reduce heating requirements. The layout of the office was changed to enable greater energy efficiency and ensure the office was as comfortable as possible while also reducing demand for heaters.

Main contractor, Coffey are, utilising 60% GGBS Concrete in the base and 30% GGBS Concrete mix in the wall pours. As well as the environmental benefit of utilising a by-product, GGBS replaces something that is produced by a highly energy-intensive process. By comparison with Portland cement, the manufacture of GGBS requires less than a fifth of the energy and produces less than a fifteenth of the carbon dioxide emissions.

Recycling demolition waste
A comprehensive site waste management plan was developed to ensure maximum recycling, reuse, and recovery of waste with a diversion from landfills. The demolished existing concrete tanks were reused as hardcore for haul roads. Excavated topsoil to be reused on-site as berms to a reservoir. Article 27 by-product applications completed to designate the waste soil and stone as a by-product and therefore allow its use in place of raw material on sites with planning in the locality.
