As far as I'm aware, there are no requirements for outdoor receptacle outlets to be multiwire branch circuits. However, there may be some other safety requirements you'll want to consider.
Ground-Fault Circuit Interrupter Protection
If you follow National Electrical Code (NEC), the 2008 version section 210.8(A)(3) requires that outdoor receptacle outlets ...

Galvanized pipes were used pre-60's. So it was to code for its time but its the worst piping to use for water. Hot water lines clog up a lot with galvanized if you have hard water.
