Downspout Drainage - Schedule 40 or 80?
Hello,
I plan to bury 4" PVC pipe about 8-12 inches underground to drain the downspouts away from the house. The pipes will extend about 30 feet through the front yard.
There is a good chance that heavy equipment (e.g., a 20,000 lb boom lift) will cross over the buried pipes. Should I use schedule 80 pipe instead of schedule 40? Would laying sheets of 3/4" plywood on the yard above the pipes to help distribute the weight of the machine would suffice?
I've been having a hard time finding a supplier that carries schedule 80 PVC, but I want to do this project correctly.
Thanks for your advice!

Plumbing PVC has a much thicker wall than sewer pipe, although I think it is still Sch 40. You would be surprised how much the weight spreads out when it is buried in the ground.
As far as the boom lift, plywood will also help distribute the weight to help damage to the ground. I think the pipe will be just fine.
