Odour Assessment Compliant?



This was an announced enforcement visit, having regard to complaints received by the EPA.

The Certificate of Authorisation issued to Irish Water on the 14th of October 2014, required the installation of an integrated Constructed Wetland as per Condition 3.3. To date there has been no progress in addressing Condition 3.3 of the Certificate A0522-01 or applying to the EPA for an amendment to the Certificate in this regard. The EPA noted during the visit that an ICW had not been installed at the site, as per Condition 3 of the Certificate of Authorisation.

Following the site visit carried out on the 3rd of May 2017, the EPA opened a Compliance Investigation (Ref: CI001469) seeking proposals in relation to the treatment system and sewer network.

Irish Water is reminded of its obligation to comply with all conditions of the Certificate of Authorisation (A0522-01) and respond to CI actions as they are raised.


The EPA carried out an inspection of the Kilronan Cottages agglomeration following the completion of remediation works to the percolation area in March 2022 and having regard to recent odour complaints. 

The EPA Inspector carried out an odour assessment in the environs of Kilronan Cottages on 20/07/2022. No odours associated with the activities at Kilronan Cottages Certificate of Authorisation Reg No. A0522 were detected by the inspector off site on the day. The assessment was followed by a site visit to the septic tank and the newly installed biofilter and percolation area.

The EPA inspectors noted the remediation works completed on site including the newly installed pump chamber and biofilter and percolation area. Preliminarily monitoring results indicate improved effluent quality from April to June 2022.

The EPA has an open compliance investigation file in relation to the waste water treatment system for Kilronan Cottages. Irish Water shall continue to monitor the effectiveness of the newly installed biofilter and percolation unit report through Compliance Investigation CI001469 as appropriate. The next compliance investigation action update (CI action A113903) is due on the 30/09/2022.
