Trench for French Drain
We used shovels instead of a trencher because the homeowner has an underground sprinkler system that we obviously wanted to protect. Using a trencher would have no doubt destroyed many pipes and required fixing after the french drain installation.
You can see in the above photos that we placed the french drain along the side of the house to protect the house from drainage coming from the backyard and side yard. Water enters the french drain and is safely diverted to the exit point in the front yard
