NI Water has announced a £1.6m investment as it completes work on a water pumping station in Londonderry.
The company said it upgraded the pumps and control panels at the Ballinagard station on Culmore Road to enable water to be pumped to the nearby Croppy Hill reservoir.
Infrastructure Minister Nichola Mallon said: "This £1.6m upgrade highlights the impact investment in our infrastructure can have.
"This pumping station pumps water to Croppy Hill reservoir which supplies up to 16,000 customers in the west of Derry. I want to see more investment in sustainable water and drainage infrastructure because it will make a real difference to people's daily lives."
Paul Davison, NI Water head of water capital procurement, said that the work helped to increase the resilience and security of the supply, particularly in emergency situations. Work was completed in December.
