Castletownshend Sewerage Scheme

Uisce Éireann has completed works on a brand new wastewater treatment plant for Castletownshend

Uisce Éireann, working in partnership with Cork County Council, has completed works on the Castletownshend Sewerage Scheme in Co. Cork. This project involved the construction of a new wastewater treatment plant (WWTP) and sewerage infrastructure which has now eliminated the discharge of untreated wastewater from Castletownshend into Castlehaven Harbour. The new WWTP will serve a population equivalent of 531. 

Two mature sycamore trees located along the pipeline route are a distinct feature of the village. In order to protect the integrity of this local landmark, directional drilling was utilised in order to navigate around the root system and install the new pipelines, without compromising the health of the trees. Glanua delivered the works on behalf of Uisce Éireann.

• A new WWTP in the north-east of the town.
• Construction of a new pumping station.
• Upgrading of the existing main street sewer network.
• 500 metres of new pipes to separate storm water from wastewater.
• 325 metres new gravity pipe to bring untreated wastewater to the WWTP.
• Conversion and 30-metre extension of existing outfall into new storm water overflow at the quays.
• Construction of new and separate 290 metres outfall from WWTP.

• Eliminating the discharge of raw sewage and improving water quality in Castlehaven Harbour;
• Protection of recreational waters for swimming, sailing and sightseeing;
• Better health and integrity of the environment;
• Sized to accommodate future population growth;
• Ensure compliance with national and EU regulations relating to the treatment of wastewater.

Any person or business wishing to get a new connection to public wastewater collection infrastructure must contact Uisce Éireann. You can make a pre-connection enquiry in order to establish whether a connection to the public network is feasible, where the connection can be made and any associated charges.

• Nationally, wastewater infrastructure has been built in 31 areas around the country where there was no sewage treatment before.
• 40 out of 50 untreated agglomerations either have brand new infrastructure in place or have projects under construction.
• Over 70% of total volume of raw sewage has been eliminated by prioritising areas that make biggest impact, with a total investment of €750 million.
• We are on track to eliminate the vast majority of raw sewage discharges by the end of 2025.
• In Cork, works are also complete on wastewater infrastructure in Castletownbere and Inchigeelagh to eliminate the discharge of raw sewage, while works are currently underway in Whitegate & Aghada and Ballycotton.
