Just a friendly word of caution... My hubby is a septic installer. Where we live, unless your grey water system (that just runs out into your landscape or yard) is grandfathered in, it is illegal to do so. Here, the penalties are pretty stiff so please be careful and check with your local environmental health department so that you never hear that dreaded knock on your door or receive that lovely peice of certified mail. All it takes is a neighbor that is miffed at you or an inspector driving by.
