Septic Tanks and your Responsibilities


Donegal County Council is in the process of carrying out inspections of wastewater treatment systems and septic tanks and will continue to do so for the foreseeable future.


Donegal County Council would like to issue the following advice to all owners of septic tanks in the county:


  • As Septic tanks accept waste from toilets and contaminated or grey water from showers, sinks, washing machines and dishwashers, it will contain a wide range of harmful bacteria and germs, as well as household chemicals and waste materials.
  • You have a duty of care to ensure that it works properly so as to ensure it doesn’t pose a threat to human or animal health or to the environment.
  • The effluent from a septic tank should not be allowed to discharge to any watercourse, but should be filtered through the soil in a percolation area or soakpit.
  • It is necessary to remove the solids by desludging the tank every few years or more frequently depending on usage
  • Roofwater and surface water from paved areas should not be allowed to enter the septic tank
  • Remember to register your wastewater treatment system online at , if you haven’t already done so



Further information on the procedure & Septic Tanks in general is available online at or by contacting Environment Department, Donegal County Council Tel: 074-9153900.
