How to install Subsurface Drip Irrigation (SDI) or Waste Water Dispersion Systems

The project below was completed in "1.5 hours including a break for an iced coffee" according to Andrew Walladge from Berri Native Plants in Berri, Australia, using the TRENCH’N edge Trencher. Andrew described the job as “We started the first trench and caught the waste on tarps to fill the final trench. Each subsequent trench fills the trench before it.” Andrew is an irrigation contractor and grower of native Australian plants in Berri, South Australia, east of Adelaide.
