Today we lowered a 3" main for a construction project. A new restaurant is under construction on a property we manage the irrigation system. The main was lowered by the construction company late last year for a new driveway. But they did not take into account that the curbing would be going down 18" and that the curbing contractor said he needed 6" of fill on the main or he would not curb.
So today we lowered the 3" main, a 1 1/4" lateral line and a 3/4" drip feeder line.

Pulled out the 2310 and went digging...

You're going to make Purp jealous. Nice pics LR. I've got some to share but I'm too beat. I'll try about 4am or so.

It DOES look like something we'd be involved with. :)

Thanks for the pics.

All that effort and you didn't sleeve it?

There is going to be a drive on it right? I would have dropped a 6" and a 4" sleeve in that trench. We sleeved anything that was eventually under concrete.

LR... I take it that you're a man that takes things a little "above and beyond" what they should? ... i.e. they want a main lowered, say, 12" and you'll lower it 18" to give more of a buffer zone in case they miscalculate the actual new depth they need. The cost difference is pennies but saves the customer big bucks if they miscalculate.

I also note that the equipment is there to aid you and you don't overuse it. We also dig next to the problem with the hoe and then hand dig into the excavation to be carried out by the hoe. Buffer zone of not hitting piping or wiring is built in so extra repair work is not necessary and also speeds up the process.

Good job! :clapping:

That's what I call a buddy trench. :)

Ditto.
