Under the Water Services Acts 2007 and 2012 (Domestic Waste Water Treatment Systems) Regulations 2012, the owner of a domestic waste water treatment system is responsible for its maintenance and renewal and shall ensure that its parts and components are fit for purpose, operational where appropriate and kept in good order and repair so as to prevent a risk to human health or environment.
Furthermore, Section 70(5) of the Water Services Act 2007 as amended, places an obligation on the occupier (owner if unoccupied) of a premises to notify the local authority, “when a leak, accident or other incident occurs concerning waste water discharges from the premises to a drain, sewer or treatment system which is causing or likely to cause a risk to human health or safety, or the environment”. Financial Assistance towards the remediation, repair or upgrading works to, or the replacement of a domestic waste water treatment system is available under new and revised grant schemes and details of the Terms and Conditions for each scheme can be found on the Department’s website, https://www.housing.gov.ie/water/water-quality/domestic-waste-water-systemsseptic-tanks/domestic-waste-water-treatment-1
The day to day administration of these grant schemes has been devolved to the local authorities and individual queries should be addressed to the relevant local authority.
