Irish Water is progressing with its plans to upgrade the Malahide Water Supply Scheme. This project will see Irish Water invest €2 million, to construct a new reservoir north of Seamount Heights and 2kms of new trunk water mains providing 2,300m3 of additional water storage for the Malahide and Portmarnock area. The project will improve the security of the water supply for homes and businesses in the area. Irish Water submitted the planning application for this project on Monday, 11 July 2016.
The existing reservoir has supplied Malahide and Portmarnock since 1971 and due to significant population growth in the area a new reservoir is required. The location of the new reservoir is close to the existing reservoir at Seamount.

William McKnight, Programme Specialist with Irish Water said “We are pleased to submit this planning application, this is an important project for Irish Water as it will improve the security of water supply for both Malahide and Portmarnock. The current reservoir has been serving the community for over 45 years. Over 20,000 people live in Malahide and Portmarnock and Irish Water is committed to investing in the water infrastructure for the our customers to ensure it meets and supports the development needs of the area long into the future”. 
Subject to planning permission being granted and the acquisition of the lands from third parties, it is expected that construction will begin in 2017 and is estimated to take 12 months to complete.
