10 August 2022

Uisce Éireann, working in partnership with Cork County Council, is delighted to announce that construction to build new wastewater infrastructure for the Castletownshend area has commenced. This important project will eliminate the discharge of untreated wastewater into Castlehaven Harbour, resulting in improved water quality that will enhance local amenities and add to a platform for social and economic development.

Glan Agua, who are carrying out the works on behalf of Uisce Éireann, are expected to have the construction completed by mid-2023.

Speaking about today's milestone, Anthony Kavanagh, Asset Delivery Regional Lead with Uisce Éireann, said: “We are delighted to be delivering this important project on behalf of the local community in one of the most beautiful coastal villages that Ireland has to offer."

This significant investment will boost Castletownshend by enhancing the local environment and improve water quality for the likes of swimming, rowing, and sailing. Eliminating the discharge of untreated wastewater into Castlehaven Harbour will only add to the scenic views and coastal walks around Castletownshend."

Anthony added: “This project will involve the construction of a new wastewater treatment plant and new pumping station. It also involves upgrading the existing sewer network and construction of nearly a kilometre of new pipeline and outfall."

We look forward to working with the local community in Castletownshend to deliver this essential project that will ensure cleaner and safer effluent being discharged into Castlehaven Harbour.”
