I'm actually doing a little work tomorrow. Some jerk added onto a drip zone, and that zone didn't have enough pressure as it was. The addition went under the drive and uphill about 200'. No water was getting to the end of the line, and there was only one drip emitter at each new tree. We are adding to another zone at the top of the hill, and hand digging through native area and ground cover. I will help dig for an hour or so, and let the guys do the rest. I'd rather have three guys dig it early in the morning.
We did some work at my house last week, and will post photos soon. Another "Team Building" job
