Hi Slippy,

It's your project and you can make it as complicated as you want. But if you wanted to save a bunch of time and money, then you just leave the end open to the elements. Nothing is gonna go crawling up your pipe. Even biodrgradable soap is strong enough to keep everything out!!! If your prone to worrying about these things, a P trap at the end will work as well as a flapper.

In the places that I've seen this done, and it's very common all over the place, especially at hunting cabins in the mountains all over the west, is to just burry the pipe a foot or two underground and run it until you come to a place to dump it out. Usualy a few hundred feet is plenty.

The area you dump it will grow like crazy and become an oasis of plants and wildlife!!!

Whatever you do, put in cleanouts facing oposite dircections and space them out to the distancy you can reach with your snake. No point putting them in every hundred feet if you can only go 50 feet. /forums/images/graemlins/grin.gif

Put them in so you can go either way up the line. Imagine looking at the line from the side and the pipe is a straight line. The cleanouts should look like the letter U. The angles at the bottom of the U direct the snake in oposite directions.

One of the probems with emptying grey water into a barrell or perforated pipe is the amount of hair that goes down the line. Hair keeps building up over time and is just about impossible to break down. With your method, it's just how long until you have a clog.

Of course, with minimal usage, this might not be an issue.

like others said, run perforated pipe, (starting out a little ways form the cabin,) in you're trench, filled with gravel, and empty it into a drum/barrel that is burried under ground & surrounded by more gravel, what seaps out into the gravel trench is fine and what makes it to the barrel will fill it slightly abd slowly let it seep into the ground...

Actually, there is a book about it and it recommends a mulch basin. It also recommends using 2" pipe.

The name of the book is "Branched Drain Greywater Systems" by Art Ludwig.
