Windmill Hill Reservoir and Trunk Watermain to Ratoath
Irish Water is progressing plans to increase the storage capacity at Windmill Hill Reservoir and replace the existing watermain between the Reservoir and Ratoath, improving security of supply for residents and businesses in Ratoath and Ashbourne.
Irish Water, working in partnership with Meath County Council, is replacing over 7km of problematic, old water mains in Ratoath that were prone to frequent bursts and caused water supply disruptions for customers in both Ratoath and Ashbourne. The old water mains are being replaced by high density polyethylene (plastic) pipes which will address low water pressure particularly in Ratoath which are encountered during periods of peak demand and enable long term growth of Ratoath and Ashbourne.
In addition, Irish Water also plans to construct an additional storage reservoir at Windmill Hill. This additional infrastructure will mitigate the impact any bursts in the existing watermain that supplies Windmill Hill Reservoir from Staleen Water Treatment Plant which is located between Donore and Duleek.
What are the benefits of these works?
- Improve water supply security and resilience for homes and business in Ratoath and Ashbourne;
- Increase the water transfer capacity to meet current demand and facilitate development in Ratoath and Ashbourne
What is involved as part of this project?
- Construction of a new 450/350mm diameter trunk watermain that will replace the existing 300mm asbestos cement main between Windmill Hill and Ratoath. The replacement watermain will run parallel to the existing watermain predominately in public roads as follows:
- L5003 from the reservoir site at Windmill Hill to the junction with the R155 at the entrance to Tayto Park.
- Along the R155 from the entrance to Tayto park to the junction with the R155 in Ratoath town.
- Construction of an elevated 4,700m³ circular concrete reservoir adjacent to the existing Windmill Hill concrete reservoirs.
What is happening next?
Consultations remain on-going with landowners impacted by the proposed works and Irish Water plans to submit a planning application to Meath County Council for the proposed Reservoir.
Ground investigation surveys have been taking place in recent months and will continue to take place during August 2021.
Irish Water plans to commence a procurement process for the construction of the new Reservoir and watermain in Q4 2021. We will endeavour to keep you updated as the project progresses.
Where will the construction be carried out?
The new reservoir is proposed to be built adjacent to the existing reservoir at Windmill Hill which is located between Curragha and Kilmoon Cross.
The replacement watermain will run parallel to the existing pipe predominately in the R155.
Will there be traffic management in place?
As the replacement watermain is in the public road the project will require a significant amount of Traffic Management. Typical traffic management measures may include temporary traffic lights, stop/go systems, road closures and diversions. Signs will be erected in advance of works commencing to ensure road users are aware of current and upcoming traffic measures.
Local access and emergency access will always be maintained and regular engagement with the community is planned throughout the project duration.
We will provide further information on traffic management measures as the project progresses.
