A Kitchen Renovation Suggestion
A few years back, Mr. P and I added on to the house and redid the kitchen. One of the things I insisted on when changing the kitchen was to add a second, FULL-SIZED SINK. We both cook and we collide at the sink.
Luckily for me, not only did Mr. P add the second sink, he tied it into a different gray-water drainpipe. Big deal, you say. You darn betcha, since in a fit of refrigerator-cleaning enthusiasm I managed to clog the living daylights out of the sink we use most often.
It took over 48 hours and two sizes of drain augers for me to clear out the pipe (Mr. P being out of town when desperately needed, darn it)and I am here to tell you that the second sink, not tied into the clogged line, was wonderful.
If you're thinking of redoing your kitchen (and what Chowhound isn't?), do consider a second full-sized sink.
Very cool! How does a gray-water pipe work, ie where does it drain to? Did you need to get a special permit for it? Did you use a contractor and did he know how to do it? This sounds like a great idea! My SO and I have a sink in our kitchen island--not as big as our main sink, but used just as much. Our biggest problem with it is the water pressure. The house was originally built with a waterline for a bar sink, not the bigger one we have there.

A gray-water line is any line that doesn't contain sewage, such as the kitchen sink or the washer. It drains into the same line as the rest of the house, although some people in rural areas have been known to separate them and drain the gray-water into ravines. We really don't want to think about that, though.
Since the wonderful Mister P IS a contractor, he knew what to do as far as drain lines are concerned (ours is tied into our septic system). It was possibly an accident that the second sink was not on the same drain line as the primary sink, but I've given him the benefit of the doubt here.
As far as water pressure is concerned, you might be able to add a pressure tank and increase the water pressure.
re: Non Cognomina
The rules on grey water disposal vary by locale. Most peoples' sewage, black water, grey water, all goes to the same place. If you're in the country and on a septic system, diverting grey water to a dry well instead of the septic system will let your septic system last longer, saving $$.
A dry well is basically a hole in the ground, with rocks and sand at the bottom, that it drains into (there's a top on it so you don't fall in).
But it may not be allowed by your local building code, so ck with them.
