An Taisce Report

The Mutton Island Waste Water Treatment Plant (D0050) was opened in 2004 with a claimed capacity of 90,000 people equivalents.

In 2014 it was upgraded to have a claimed capacity of 170,000 people equivalents (reduced by Galway City Council to 145,000 people equivalent to allow for Summer tourists). Local papers carried of stories in 2004 (and again in 2014) of how the Mutton Island Waste Water Treatment Plant would guarantee the beaches in Galway City would now be safe to swim in.
The reality however is that is not true.

Groundwater Water Treatment Pressures

adminLeave a comment

Significant pressures have been identified for waterbodies that are At Risk of not meeting their water quality objectives under the Water Framework Directive. While there are a multitude of pressures in every waterbody, the significant pressures are those pressures which need to be addressed in order to improve water quality. Many of our waterbodies have multiple significant pressures. A robust scientific assessment process has been carried out to determine which pressures are the significant pressures. This has incorporated over 140 datasets, a suite of modelling tools, and local knowledge from field and enforcement staff from the Local Authorities, Inland Fisheries Ireland and EPA. Impacts from water treatment discharges include chemical and sediment pollution.
