Irish Water invests €1m in sewer upgrades

Irish Water, in collaboration with Limerick City and County Council, is investing €1 million (US$1.2 million) in a project to survey, assess and reline sewers in the city centre.

The project is designed to address odour issues, reduce sewer flooding and upgrade the existing infrastructure for the benefit of city centre businesses and residents.

The initial phase will involve CCTV condition assessment and extensive cleaning of old culvert sewers in the area, as well as site investigations and the installation of new access shafts for future relining activities.

To prevent aboveground works and heavy plant works associated with civil construction methods, the second phase of the project will involve the insertion of precast plastic liners into the existing masonry sewers to improve the system’s structural stability and improve its performance.

“This is an essential project for Limerick City and in delivering it we are mindful of the impact the works could have on businesses,” said Irish Water Capital Programme Regional Lead Eunan Canavan.

“While the initial surveying stage will involve minimal disruption, some local excavation will be required to enable access to the sewers.

“We will be engaging with affected businesses and residents ahead of any such works.

“Irish Water and our contractors GMC Group have also agreed that no works will be carried out during the month of December in order to avoid traffic congestion during the Christmas period.

“Irish Water and the contractors will make every effort to ensure odours are kept to a minimum and trenchless techniques will be used for this project in order to reduce impact on businesses and residents.”

Sewer cleaning, CCTV surveys and site investigation works are scheduled to take place from July 2018 to May 2019, while liner installation is scheduled to take place between January and February 2019.
