The largest disadvantage (that I'm aware of is that you need a head of
water BELOW the point you are pumping from.
This can be achieved by sinking a pipe to below the aquifer inlet point.
Efficiencies are usually around 35% - while this is significantly below
that of conventional pumps it still may be viable.

Here are some tabs I have open on the subject at present:

Brumby XS1c pump for deep water

   - Water depth is and remains over 1/3 of the total vertical lift. The
   deeper you can submerse the pump in water, the more it will deliver. Water
   level self-regulates by virtue of the pump's design and operating
   principle. Pump will still operate with substantially reduced
   submersion/lift ratio, but water delivery rate may be low
   - Delivery rate can be as much as 8000L/hr+, depending on the water
   source, submersion in water, lift above the water, air supply and piping
   size.
   - Vertical lift up to 100m (300ft) is no problem with a regular 5 to
   15cfm off-the-shelf compressor
