Just put in a sump pit and pump outside or under your shed for your drains to run into. Then use a garden hose for your discharge line. You could hang the hose on the side of the shed, just like a garden hose, when not brewing. I don't imagine freezing is a big problem in Glendale, so you could also bury the garden hose a few inches under the surface.
Edit Also you never really have enough outlets, so when wiring, add about 25% to the outlets you think you want or need.
