Helping out with the excavation duties to install a new Advanced Enviro-Septic System (AES) out at the Barossa Valley. I've done plenty of these installations from my time in Queensland, however here in South Australia these systems seem to be a fairy new evolution in longer lasting, environmentally friendly and efficient septic systems. So that is exactly what I was doing over the course of three days with the help of the owner and plumber to get rid of their old septic system and install this much more advanced one. The first task was to dig up the old tank using my mini excavator operator skills, re-excavate the pit to ensure the new tank would fit and gently lower it in.
Once the new AES tank was installed, which was only half the job complete, I got started on the task of excavating the area where the Patented Pipers were to be laid. These pipes are the key to how the AES system works and as such the area needs to be precisely levelled and prepared in a particular manner. While digging the area out, I noticed the earth layer was extremely solid which wouldn't be to good for the dispersal of the water waste once it made it through the sand layer. So I Scarified the soil, which punctures and breaks up the hard dirt layer to increase water absorption. A bed of sand was then laid over the top, ready for the patented pipers to be installed
Now the way these patented pipes work is extremely smart and interesting for anyone thinking about a new septic system. Here's some great information on how an AES system works. But needless to say, these patented pipes are state of the art in how they are engineered to work. What you may not see clearly in the pictures below is that the pipes have been connected up to the new septic tank and will now provide a much larger area for the waste water to be dispersed in, making the evaporation and absorption more eco-friendly for the owners yard.
And finally the finished product! A well laid out plan for an AES system coupled with my skills and knowledge as an Earthmoving Contractor have ensured this home owner now has a state of the art septic system. The additional sand layer on top of the pipes was the most fragile part of the whole operation. The sand needed to be filled in gently around the pipes to prevent movement but not compacted in a way that would compress them.
Lastly, a layer of earth back over the top. It should be noted also that time will be needed for the sand and earth layers to naturally compact themselves, meaning the area will need to stay clear of cars and the like.
Overall, another happy client that I have enjoyed working for. I’m all about efficiency and perfection when I operate my Bobcat, Excavator and Tipper. When I quote a job for a potential client, I also provide my expert advice on how they should get the job done and ensure any other materials that are needed are on site and ready to go to. This avoids wasting unnecessary time and money for us all.
