Northern Ireland Water (NI Water) claims it has invested around £8.6 million to improve efficiency at its wastewater plants in the last two years.
It was part of the water company’s ‘Base Maintenance Wastewater Investment Programme’ from November 2011 to spring 2013 and plans to invest a further £15.9 million by next year.
The investment scheme was set up with the aim of refurbishing more than 50 minor wastewater works across the country.
Regional Development Minister Danny Kennedy said: “The latest technology that has been used has already increased efficiencies to the wastewater treatment plants, including cost reductions in running cost and reduced energy use.
“Each project represents a significant investment in modernising wastewater treatment in rural areas. They bring environmental benefits for local communities.”
