Home : Environment : Septic Tanks or Domestic Waste Water Treatment Systems : Registration of Septic Tank or other system (Protect Our Water)

The Water Services Act 2007, as amended by the Water Services (Amendment) Act 2012, set out the requirement to register your septic tank or domestic wastewater treatment system.  The Local Government Management Agency (LGMA) has developed a central on-line registration system and manages the system on a shared-service basis for the water services authorities.  Registration commenced on 26 June 2012 and certificates were initially valid for a period of 5 years.  Full details are available on the Domestic Wastewater Treatment Systems Registration website https://www.protectourwater.ie/

Under the Act, owners of domestic waste water treatment systems are required to ensure that their systems are on the register. Your registration will contribute to the protection of Ireland's ground and surface waters.

Please Note: If you have already registered, you do not need to re-register. The requirement to re-register every five years is being removed from the legislation. Your existing certificate remains valid.

All septic tanks and other types of treatment and disposal systems for domestic waste water should be registered.  This commenced in February 2013.

For the first 3 months the cost to register was €5 increasing to €50 thereafter.
