How do you know what type of Septic Tank you have? We will talk about conventional systems with Septic Tanks and Absorption Trenches, Grease Traps and Grey Water (Sullage).

Most older residences have conventional systems compared to newer houses which have HSTPs.

Septic tanks are the larger of the tanks in your yard which can vary in sizes.

  • 1600 Litre approximately 1300mm across
  • 2500 Litre approximately 1550mm across
  • 3000 Litre approximately 1750mm across

These tanks are solely for toilet waste, the solids are caught in the tank and partially digested by bacteria and the reminder settles to the bottom of the tank until it reaches a level where pumping is required.

The excess water from flushing is sent to absorption trenches under the ground which consist of gravel pits where they can dry out through evaporation.Pumping out time of these tanks vary with the size tank and the number of people in the household.

GREASE TRAPS

Grease Traps are solely to catch the kitchen grease from your sink or dishwasher and can be found normally outside the kitchen window.

They are normally about 350mm round or rectangular shape with 2 lids that join in the middle about 900mm x 500mm.

These grease traps should be cleaned often at least every 6 months to prevent excess grease build up in the trap and pipes causing blockages also creating bad odours.

The excess water from the grease trap flows into the Grey Water (Sullage)

GREY WATER-(Sullage)

Grey Water Collection

Grey Water (Sullage) is a tank slightly smaller than your 1600 litre septic measuring about 1000mm across, the waste that comes into this tank is from showers, washing machines, laundry and bathroom sinks.

This waste is considered recycling water for irrigation please refer to our Grey Water page for proper uses.

It is sprinkled out onto grass or ornamental plants for irrigation, all hoses and sprinklers must be purple in colour to identify it is grey water and not fit for Human or Animal consumption.
