A YouTube creator known as The Mountain Wizard, or Sean, is building an off-grid motorhome site and has shown how he will handle grey water without conventional plumbing. He said the system requires roughly 50 feet of 4-inch lateral line with pre-drilled holes, laid with the solid side up so liquids drain into the soil. The unfinished site also calls for six 200-watt solar panels totalling 1,200 watts on a tracking mount, a custom carport to shelter the motorhome from wind and rain, a water tank, gutters and a connected water pump. Sean told commenters that the local soil drains well enough that extra gravel is not necessary for the grey water setup.
