The Environmental Protection Agency says delays in upgrading Ballyvaughan and Kilkee are extremely concerning.
A new report says those villages, along with Clarecastle, Kilrush and Liscannor – continue to release raw sewerage into the environment every day.
While Clarecastle, Kilrush and Liscannor are set to have upgrade works completed in 2023, Ballyvaughan will be waiting until 2024, with Kilkee’s facilities not due to be ready until 2025.
The report also states that Ennis, Lahinch and Shannon failed to meet EU waste water treatment standards last year.
Speaking to Clare FM’s Josh Prenderville, Senior Inspector with the EPA Dr John Feehan says further delays are prolonging public health risks.
