Domestic Septic Tanks

Domestic Septic Tanks

Septic tank registration, guidelines for inspections, grant applications and information for owners

The Water Services (Amendment) Act 2012 provided for the introduction of a registration and national inspection system for domestic waste water treatment systems (septic tanks).

The key objectives are:

  • To enhance and protect public health and the environment which will, in turn, benefit rural dwellers in terms of a better quality of life and better quality water.
  • To protect our environment. This will also have positive economic benefits for the tourism, recreation, agricultural and food-producing sectors, all of which rely on clean water.

Information for Owners of domestic waste-water treatments systems:

  • You need to know where your septic tank is located.
  • You need to operate and maintain the system so it is fit for purpose and fully operational.
  • The system can not pollute the environment by discharging/leaking waste anywhere it is not suppose to ie. into the ground or any water source.
  • Roof water or surface water run-off can not enter a domestic waste water treatment system.
  • The system should be de-sludged at intervals appropriate to the tank capacity and the number of persons resident in the premises connected to it or as recommended by the system’s manufacturer.

Guidelines on Inspections:

  • All such inspections in County Meath will be carried out by trained inspection staff from Meath County Council.
  • Dwellings due for inspection under the National Inspection Plan will be notified directly in writing by Meath County Council in advance of the inspection taking place. However, it is also advisable to seek proof of identity from any person seeking to carry out any inspection at your property.
  • The Act requires water services authorities to maintain a register of domestic waste water treatment systems in their functional areas.
  • 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.
  • All septic tanks and other types of treatment and disposal systems for domestic waste water should have been registered not later than 1st February 2013.
