The water energy harvester you can use greatly depends on the specific flow of the water energy source you have available (for example, does the water come from a hill or does it flow relatively horiontal ?). In addition, it also depends on what your objective is (ie do you want to produce electricity, generate simple mechanical work, [http://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity store electricity] ?), your budget (which determines the size of the device you can build) and the impact on the water source (it is best not to use the full potential energy of the water source so that organisms living in the water source are not disturbed too much).

Microhydro systems are specifically those systems that are not grand in scale. Damming a river usually will not qualify as microhydro, but partially diverting a stream into a holding tank and running the water into a small hydro-electric turbine or pelton wheel is more along the lines of what the term microhydro refers to. Microhydro systems are typically off the grid and provide energy for a small community or a single family/user.

The following article is a brief overview of the more technical aspects and considerations needed to design and construct a microhydro system.

Choosing a water energy harvester

The water energy harvester you can use greatly depends on the specific flow of the water energy source you have available (for example, does the water come from a hill or does it flow relatively horizontal ?). In addition, it also depends on what your objective is (ie do you want to produce electricity, generate simple mechanical work, store electricity ?), your budget (which determines the size of the device you can build) and the impact on the water source (it is best not to use the full potential energy of the water source so that organisms living in the water source are not disturbed too much).
