On Site Wastewater Disposal Methods
There are several options for how wastewater is irrigated or disposed of on your property. The Geotechnical Report will determine where the wastewater is disposed and the size of the area required. This area must be dedicated for wastewater disposal only, you can’t build over it with a shed for example.Your local council may have certain requirements you have to meet.
On Site Wastewater Disposal Options
Your local Council may have requirements for how the wastewater from your AWTS or septic system is irrigated on your property. BluenGrey can advise you of what regulations you will need to meet for your property.
Key Methods of On Site Wastewater Disposal
There are several options and BluenGrey can assist with information and installation of all of these methods.
Method 1 – Sub Surface Irrigation:
This is effluent grade poly pipe that is buried under the ground, with drip emitters spaced evenly to allow a predetermined amount of wastewater to be released. Our system design includes mesh filters, root inhibitor, flush point valves and air release valves.
Method 2 – Surface Spray Sprinklers:
There are several ways to install surface spray sprinklers. It can simply be a line of effluent grade pipe with 4-6 rose sprinklers or a grid like pattern with multiple quick coupling valves and sprinklers at ground level or above.
Method 3 – Evapotranspiration Beds:
Evapotranspiration beds are used where soil conditions are less suitable for absorption trenches and where evaporation and transpiration rates normally exceed rainfall. Typically a square area of ground is excavated and filled with gravel and plumbing pipes to disperse the water evenly.
Method 4 – Absorption Trenches:
An absorption trench can vary in design and size depending on the soil type. Typically, it’s a trench 600mm wide with plastic arches, geotechnical fabric and gravel. Wastewater flows into the trench from the septic tank or AWTS.
BluenGrey can advise on the best method for your particular property and septic system, taking into account any requirements that your Council has and subject to a Geotechnical Report.
