Client: Galway County Council
Location: Co. Galway, Ireland
Project Value: €5.3m
Description: The aim of the project was to substantially reduce water leaks in Ballinasloe town and curb pollution of the River Suck due to sewer overflows
Among the works undertaken by Ward & Burke was changes made to the town’s water network making it more resistant to frost, and to reduce regular sewer overflows that cause the pollution to the River Suck at Ballinasloe in Co. Galway.
The main contract elements included:
Water Supply Network
8.3km of old water mains that were no longer fit for purpose and resulted in regular interruptions to supply were replaced, delivering improvements in water quality and service for consumers in Ballinasloe, Oranmore, Headford and Athenry all of which were located in urban areas. Lower maintenance costs and a reduced level of leakage was also achieved as a result of the newly upgraded network. The ability of the network to deal with cold snaps and frost events was significantly improved.
Construction of approximately 8.3km of polyethylene and ductile iron pipework and associated fittings to supplement or replace existing cast iron, AC, PE and uPVC watermains.
The upgrade of 2.43km of surface water sewers in Ballinasloe improved the capacity of the sewer network to deal with increased flows during storm events. Surface water separation will alleviate overflows in the town’s sewers and reduce the volume of storm water sent to the Ballinasloe Wastewater Treatment Plant for unnecessary treatment, delivering lower operating costs at the plant. There will also be a reduction in the discharge of untreated sewer overflows and the associated pollution of the River Suck. The improved network will also have greater capacity to deal with current and future development in Ballinasloe and new gullies will improve road drainage and overall road safety for motorists.
The contract provided for the construction of approximately 3.07km of combined and surface water sewers and associated fittings, consumer connections, manholes and other chambers on the collection networks in Ballinasloe Town;
The works involved extensive engagement with the project stakeholders with a big emphasis placed on building positive relationships with the local community and businesses impacted by the works which proved instrumental in reaching agreement regarding traffic management solutions in these densely populated urban centres which ultimately assisted in the safe delivery of this project.
Complex traffic management installations were required throughout the project due to the significant interface between the works and the general public. For example, Oranmore town centre involved the installation of road closures on sections of Main Street during agreed periods. Access was maintained to Businesses and private properties during critical times such as deliveries, individuals coming to and from work etc. Trained Traffic Management operatives were on site to ensure co-ordination of traffic flow and to minimise the impact to the public. Combinations of stop/go control and vehicle actuated traffic lights and count down timers were deployed throughout the project.
