Glenties/Dungloe Sewerage Schemes & Wastewater Treatment Plants

Wastewater Project

The towns of Dungloe and Glenties are located on the west coast of Co. Donegal and, prior to this project, were both served by old and outdated septic tanks and outfalls. This €7.2 million investment involved replacing the old septic tank systems in Dungloe and Glenties and with modern wastewater treatment plants serving over 1,000 households. The new plants ensure treated effluent meets EPA standards and allow for future population growth and economic development in these towns and surrounding areas.

€7.2 million

  • Facilitated the overall current and future growth and physical development of the towns and surrounding areas 


  • Design and construction of two new wastewater treatment plants, pumping stations, detention tanks, outfall pipes and rising mains in Dungloe and Glenties, serving a population of approximately 4,000 people
  • Redesign and upgrade of existing pumping station in Dungloe
  • Building of new access roads to the new wastewater treatment facilities and pumping stations
