Camped out building water catchment with G&F and a few other volunteers.
Never seen one underground like that, Kent.
Looks pretty invasive. How does it work?
Slope funnels water into an inlet headwall grate, then into the pipes for storage. Originally there was to be another pipe in each run but caliche forced us to stop it short after 2 days of digging. went from 10,000 gallons to 8,000 storage. Pipes are manifolded together and then outletted to a concrete trough for wildlife.
