Electrical – split the direct wire to dishwasher to handle a garbage disposal as well

dishwasherelectricalgarbage-disposalwiring

I've just plumbed in a new garbage disposal unit under my sink. The plumbing appears to be fine – nothing is leaking so far.

Now I need to wire it in.

It's next to a dishwasher, but the dish-washer has a direct wire from the circuit box in the basement. I don't want a run a whole new circuit up from the basement, and I already have the romex for the dishwasher coming up, and wired into the dishwasher about 2 feet away.

What are my options for using that existing wire? Can I split it and direct wire both? Can I turn the romex into a socket, and plug both into that?

Something like this, but with a double-socket.

I only have 2005 NEC handy, but there's nothing there against using same circuit for both dishwasher and disposal.

210.23(A) Branch circuits, rated 20 or 15 amperes may feed lighting units, utilization equipment or combination of both. The rating of of any one cord and plug connected utilization equipment shall not exceed 80% of the branch circuit ampere rating.

Your local code could be different, of course. Also note, that your garbage disposal needs a disconnect switch
