Channel Drain instillation

I am looking to install a channel drain along the edge of my patio as this is where water tends to accumulate the most.

I've watched several Youtube videos on this so I think I can manage it.

I plan on using the t NDS 1-1/4 in. x 6 ft. Slim Channel Drain Kit and attaching to some PVC pipe once I did a deep trench.

I tried calling 811 for them to come and check for any buried lines in my yard, but they haven't gotten back to me.

Any words of advice before I try and tackle this endeavor?
