Wastewater Network
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;
- 2.7km of 225mm-525mm diameter concrete pipe
- 370m of 250mm-600mm diameter ductile iron pipe
- 73 No. manhole chambers
- 184 gullies
- 124 new service connections and 124 new inspection chambers
- Redirection of existing services (Water & Telecom)
- Temporary and permanent reinstatement of all surfaces along with additional road re-surfacing.
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.
