You want to cut at a 45-degree angle so that the PVC ends in a sharp point. The rest is just a matter of cementing the PVC to the adapter and attaching it to your hose. Trench, Then Tunnel. The first step in tunneling under a sidewalk is to dig a trench perpendicular to the sidewalk. You want it to be deep enough to let you tunnel several inches below the bottom of the sidewalk and as long as the PVC pipe you attached to the hose.
In the Residential Zones in our city we normally have a 30 foot street within a 50 foot Right-of-Way. This leaves 10 feet on each side of the street. We normally have our 4 foot sidewalks placed a maximum of 2 feet back from each curb. This allows space for the drainage catch basins, street signage, and mailboxes. It purposefully does not allow enough space for trees, but is conveniently narrow enough to step over (if muddy) to reach the sidewalk from a parked car. This leaves 4 feet between the back of the sidewalk and the ROW line on each side. This is space for street lights, cable TV, underground power and telephone lines. Water and sewer lines with related manholes tend to wander throughout the ROW as needed based on terrain and curvature of street and its ROW.
