Liscannor Wastewater Treatment Scheme

Wastewater Project

This project is needed to stop untreated wastewater being discharged directly into Liscannor Bay. The practice of discharging untreated wastewater to the river is no longer acceptable and Irish Water intends to rectify this problem by constructing a new Wastewater Treatment Plant and network infrastructure. This will ensure that wastewater discharging into Liscannor Bay meets appropriate discharge standards. The new Wastewater Treatment Plant will bring benefits to Liscannor in terms of health, integrity of the environment and improved water quality for all.



  • Will improve the water quality in the receiving waters
  • Cleaner water will enhance Liscannor’s amenity value and act as a platform for social and economic development
  • Project will ensure that the water quality standards set down by regulatory bodies will be achieved
  • The new pipes, pumping stations and new treatment plant have all been sized to accommodate an increase in the local population and will facilitate growth on the area


  • Construction of a new Wastewater Treatment Plant (WWTP) that will serve a population equivalent of 1,500
  • A new wastewater pumping station
  • A new terminal pumping station with a storm water storage tank
  • Sewer pipelines to bring untreated wastewater to the WWTP and treated wastewater to the existing outfall
  • The existing outfall pipe will safely discharge the treated wastewater to Liscannor Bay
  • This project is currently in the detailed design stage
