Registration of Domestic Wastewater Treatment Systems (DWWTS) including Septic Tanks

Site Assessors test sites to determine whether or not they are suitable for a domestic wastewater treatment system or septic tank, and what type of system is most suitable.

Limerick City and County Council maintains a list of site assessors who have:

  • Obtained the Quality and Qualifications Ireland, or FETAC Certificate in Site Suitability Assessment for the on-site wastewater treatment systems
  • Have up to date professional indemnity insurance of €1,000,000.00 and have provided evidence of same to Limerick City and County Council
  • Signed up to Limerick City and County Council’s code of professional conduct

This list is open to any person who meets these criteria and who wish to be included on it.

View the list of site assessors in the supporting documents at the end of this page.

Planning applicants may have their site assessed by persons other than those included on the list, but are advised that it is in their best interests to satisfy themselves that their site assessor is appropriately qualified and insured.
 

Registration of Domestic Wastewater Treatment Systems (DWWTS) including Septic Tanks

The Water Services (Amendment) Act 2012 requires water services authorities to maintain a register of domestic wastewater treatment systems in their functional areas. The Local Government Management Agency (LGMA) has developed a central on-line registration system and will manage the system on a shared-service basis for the water service authorities.

Under the Act, owners of domestic wastewater 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.

All domestic wastewater treatment systems (DWWTSs), including septic tanks should be registered not later than 1st February 2013. All domestic wastewater treatment systems (DWWTSs), including septic tanks installed after 1st February 2013, should register within 90 days of connection of the premises to the domestic wastewater treatment system.
