Hey, I had a similar situation, but not nearly as bad as yours. When I bought my house, I had a "graywater" run off from the kitchen sink. Luckily, mine was drawn away from the house a good twenty feet or so and ran down a nice steady grade into a ditch. My house wasn't move-in ready. It was a big project from the start so I didn't plan on keeping it this way. I don't think it's legal in my area to have this kind of setup and my kitchen sink was going to be moved to a different location. It's just interesting seeing these kind of things when I'm so used to all of the house water waste going into a septic system. Good luck with any other obstacles that might jump in your way with your house!
