Project Summary
This contract involved the design, construction, testing and commissioning of a new gravity sewer in Kinvara, County Galway. The works also included rehabilitation of existing sewers, consumer connections, road and footpath reinstatement, and the installation of supporting infrastructure to connect the network to a new wastewater treatment plant.
Project Description
The new combined gravity sewer, approximately 0.9km in length with most pipes sized at 675mm, was installed from the Gort Road, through Main Street (East), along Quay Road and into private lands northwest of the town, where it connects with the wastewater treatment plant. The works included both open trench and trenchless techniques. Additional elements included rehabilitation of existing sewers, provision of 37 consumer connections, and installation of a petrol interceptor. Road closures, reinstatement, and coordination with local stakeholders were essential given the touristic character of Kinvara.
