It is the drain for the Temperature and Pressure relief valve (T&P valve, or TPV). It's function is to release pressure from the water heater if the pressure or temperature of the water exceeds preset limits. Do not cap off the pipe, or remove the T&P valve or alter it in any way. Doing so could cause serious injury or death! If you notice water dripping or running from the pipe, call a plumber to check it.

There are various kinds of pressure valves. Perhaps the 2 most common in homes are the PRV (pressure regulating valve) which is on most incoming water pipes from a city supply.
