Maintaining your Septic Tank

Maintaining your Septic Tank

A registration and inspection regime was introduced in 2012 for domestic waste water treatment systems such as septic tanks.

Published on: 01 Apr 2020

The aim is to protect human health and water quality from the risks posed by domestic waste water treatment systems.  The regulations require owners of domestic wastewater treatment systems (DWWTSs) to operate and maintain their systems and this includes de-sludging.  


What you can do 

Every year, check your wastewater system, by doing the following: 

  • ensure no blockages;  

  • ensure it is properly desludged by a competent person 

  • ensure there are no pools of effluent (ponding) on the surface of the percolation area/soakaway; 

  • check for odours;  

  • check for noises, and 

  • ensure there is no sewage in nearby ditches and streams 


Use a permitted contractor to remove sludge from your wastewater system. If you are a farmer with your own land, you can spread the sludge but only in accordance with the Waste Management (Use of Sewage Sludge in Agriculture) Regulations.
