Athlone Main Drainage Scheme

Irish Water is progressing plans to upgrade the sewer network in Athlone

Irish Water, working in partnership with Westmeath County Council, is progressing the Athlone Main Drainage Sewer Network Upgrade project. The next phase of the project involves a Compulsory Purchase Order (CPO) for the lands and wayleaves necessary to complete the works.

The CPO, which is essential for the delivery of the project, will be published this quarter (subject to COVID-19 restrictions). When completed, the scheme will reduce the risk of sewer flooding in Athlone and also eliminate non-compliant sewer overflows into the River Shannon It will also improve the capacity of the sewer network allowing for current and future population growth.

Irish Water is progressing with the project procurement with a view to works commencing in the second half of 2022. Information events for businesses, residents and elected representatives will be held before the works commence.
