Irrigation Trenching Overview for Kelowna and the Okanagan Valley

Irrigation trenching is arduous work. Ensure you review your irrigation plan carefully for any missed opportunities to reduce trench work, such as using a single trench for more than one pipe. A pick and shovel are typically used, however, depending upon the extent of your project, a trenching machine may be required. A trenching machine is not an option though for flower beds or areas with ground cover because it will destroy the plantings. Watering the ground a few days before the trench work is to be done, will soften it and help to make the job a little easier.

Here in Kelowna and the Okanagan Valley, you'll need to ensure your trenches are deep enough below the frost line, as you certainly don't want to have to dig up your irrigation after the initial install, and remove all the piping, and relay. This situtation more than doubles the work.

Before you do any trenching work, place tarps or plastic sheets on both sides of each trench you plan to dig. To preserve the sod, cut through the thickness of the sod on both sides of the trench, and gently work the shovel underneath it, peeling it away, and placing it on one of the plastic sheets or tarps. Similarly, place the soil on the tarps or plastic sheeting on the other side. By doing this, replacing both soil and sod becomes a much easier task after you’ve laid the pipe.

If you want to lighten your load even more, you can hire Landscape Hold Diggers to do the irrigation trenching for you, and you take care of the piping yourself. We do the hard part!
