Letterkenny Sewerage Scheme
This project represents a further step in the continued delivery of improvements to the wastewater infrastructure of County Donegal.
Irish Water working in partnership with Donegal County Council commenced works on the third phase of the Letterkenny Sewerage Scheme on 3 September 2018. The works are expected to take approximately 18 months to complete.
The first phase of this project, which was was carried out from 2004 to 2006, included improvement works to trunk sections of the existing wastewater collection network. The second phase was undertaken between 2010 and 2012 and included the construction of a new wastewater treatment plant and a new sludge hub centre.
Road closures and diversions
In order to carry out these works it will be necessary to close a section of High Road (from intersection with Port Road to the junction at Newline Road). The road closure extends from 7am on Monday 3 September until 3pm Friday 27 September 2018.
- Traffic travelling south bound from Hospital Roundabout direction will be diverted via De Valera Road, R245 and onto Port Road.
- Traffic travelling north bound from Port Road will be diverted onto Church Lane, Castle Street, Ard O’Donnell and New Line Road.

- High Road | New Line Road | Beechwood Road | Ballyraine Industrial Estate to Middle Road/Ramelton Road Junction | Gortlee Road

What traffic management measures will be in place?
During the works every effort will be made to minimise disruption. Residents and businesses may be impacted during these works as we may need to:
- Restrict access to parking.
- Restrict traffic to one lane or close certain sections of roads to ensure that the work is carried out in the safest way possible.
- From time to time carry out some works in the evening, at night or at the weekends in order to minimise the impact on traffic flow.
- In order to minimise disruption works at key locations around Letterkenny Town will be restricted during school holidays.
In order to accommodate the Christmas period, works will cease in public roads at key locations from mid-November to mid-January.
