Under the Water Services (Amendment) Act, 2012 each water services authority is required to establish and maintain a register of domestic waste water treatment systems situated within its functional area.

The most recent Census, published in 2016 by the Central Statistics Office, indicated that there were 438,319 septic tanks and 50,750 individual treatment systems in Ireland. A total of 464,114 systems are registered at present.

The following table gives the breakdown of registrations by local authority. Statistics are not available in relation to whether a particular registration refers to an individual or shared septic tank.
