What is a failing system?

  • The property owner must maintain/service their on-site Wastewater Treatment Systems so it does not pose any risk to human health or the environment.
  • Create a risk to water, air, soil, plants or animals
  • Create a nuisance through noise or odours
So what can go wrong?

The most important thing with your septic tank is to make sure it’s emptied regularly. The frequency varies, the smaller the tank the more often it needs emptying. Your septic tank is designed to retain the heavy solids in your sewage which is what is tankered away, if you don’t do this some solids can get out to your percolation area blocking it up, also it can prevent flow into the septic tank causing manholes to overflow or back up into the house.

The other thing to check is that you tank isn’t leaking, the liquid level inside should be level with the outlet pipe to the percolation area. Its also important that none of your manholes are leaking, and that you rainwater is not going into your septic tank.

Your on-site system in conjunction with your percolation area treat wastewater by bacteria digesting it, it is therefore very important to minimize the use of detergents and never put anything down a sink or a drain that kills bacteria. Examples of this: oils, white spirits, paints, medicines, chemicals, bleaches etc.

Packaged plants need to be emptied regularly, usually recommended by the manufacturer or you service agent. They are usually split into different chambers and not having them emptied can cause the chambers to get poisoned with solids and stop the system working. Unlike Septic tanks Packaged plants need servicing/inspecting by your service agent annually as they have pumps and moving parts etc that can break down.

A packaged plant was selected for your site during the design phase for a particular reason, like site restrictions, subsoil problems etc. If your system is not working you are totally in contravention of your planning and your are polluting your own environment as the system is not treating the sewage. Again it is very important to make sure rainwater is not piped to your Packaged plant.
