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.

Rod's expertise is exceptional

We would like to thank Rod for all his guidance and patience while we were investigating water and sewerage systems, and asking a myriad of questions. We had never built before and knew nothing about what we needed for water and sewerage, so Rod was a fountain of knowledge. His expertise has been exceptional. Both the water tank and the sewerage system were installed hassle-free and passed Council inspection without any issues. We look forward to an ongoing relationship with Rod when he visits to do the necessary checks and balances of our sewerage system.

BluenGrey are a great ‘one stop shop’ service at competitive prices

Having made the decision to move to a semi-rural property at Yass we investigated options for our grey and rain water requirements. We approached BluenGrey who provided a range of options for us to select from. Their personal and professional approach, which included on-site meetings, ultimately led us to choose to proceed with BluenGrey who offered a ‘one stop shop’ service at competitive prices. The installation was trouble free and their follow-on service and advice has been excellent. We are completely satisfied with the BluenGrey services and have no hesitation in recommending them to future customers."

BluenGrey were very helpful in every respect

 From our initial conversations through to final installation BluenGrey were very helpful in every respect, and courteous and obliging with regards to my requirements. Work commenced on time as planned with pictures texted through to us during the installation showing progress. All in all job a well done with zero issues. I would recommend BluenGrey to anyone considering waste disposal units and / or rainwater tanks.

I can't recommend BluenGrey highly enough

BluenGrey are an absolute pleasure to deal with. Their Service Technicians are always professional and reliable, and I like to know that our wastewater system is looked after so we're always meeting our Council's regulations. I feel reassured knowing I can call on them should I have any worries about our system, and especially that they can respond to emergencies.
