Contract awarded for upgrade to Stillorgan reservoir
Safeguarding the drinking water supply for 200,000 people in south Dublin
Irish Water has awarded the contract for the design, construction and commissioning of a new covered storage reservoir at Stillorgan that will safeguard the drinking water supply for 200,000 people in south Dublin. The upgrade will support the growth of new homes and businesses for the next 15 years. The contract was awarded to J. Murphy & Sons Limited who will begin construction in early 2019. The project is part of a €200m investment in the Vartry Water Supply Scheme and is expected to be completed in 2022.
The existing Stillorgan Reservoir has supplied drinking water to the community for over 150 years. The reservoir is one of the last remaining of its kind in Europe, where treated drinking water is left exposed to the elements. This means that the treated drinking water is vulnerable to the risk of being contaminated by wildlife, animal waste, airborne material and could be polluted by people accessing the water.
The new reservoir will have the capacity to support future growth to 2031
John Prendeville, Project Manager with Irish Water said, “The upgrade of the Stillorgan Reservoir to covered storage is a priority for Irish Water. I am pleased to confirm that a contract has been awarded to commence work on this vital project. The Stillorgan Reservoir has served the community for over 150 years, and this project will ensure that Irish Water will safeguard the water for the future.
“The size and scale of this project is very significant. One of the three existing reservoirs at the Stillorgan site will be drained down and the construction of a new covered reservoir will be completed within the drained down area. Once the new covered reservoir is operational, the other two open reservoirs will be drained and landscaping of the site will take place. The new covered reservoir will have the capacity to support future growth to 2031. The remainder of the site will be retained for future water services infrastructure to secure the long-term supply of drinking water for the community.”
Irish Water has already invested €3.4 million to improve the disinfection of drinking water stored in the Stillorgan Reservoir enabling the removal of the Stillorgan Reservoir from the EPA’s Remedial Action List. Irish Water is committed to safeguarding the water supply for the community and providing a long-term solution for the safe and sustainable management of the water supply for the next 15 years. The investment of approximately €80 million in a new covered reservoir is a long term measure to protect and improve the water quality in the reservoir.
Irish Water will continue to engage with the local community and other stakeholders as construction progresses to ensure that we do all we can to minimise disruption.
