The problem with compressing air is that you'll lose a good percentage of your energy heating up the air.  When you compress cold air you end up with compressed hot air - which then cools down and wastes your energy.  When you expand it, you end up with expanded cold air - which heats up, and wastes your energy.

Could you figure out a way to get a shaft from the microhydro to the basement pump?  After all, the high rainfall that'll flood your basement is also the high rainfall that'll speed up your stream.
