To run electrical or drip line under an existing sidewalk, you can use a pipe or conduit that is large enough to accommodate the wires or tubing. First, dig a trench on both sides of the sidewalk, taking care to avoid damaging the sidewalk. Then, use a tool such as a tunneling kit or water jet to bore a hole or create a tunnel underneath the sidewalk to run the lines. Once the lines are in place, backfill the trenches and repair any damage to the sidewalk.
