We have a small river on our land which has a reasonable current available, especially during winter, so we want to put a water wheel in it to pump water to a height to gain some water pressure for our house and garden supply and to generate power from it too. We'll be making an undershot wheel because we have no significant drop in height available to make use of.
Pumping the water with the wheel
The water supply for our house needs to be raised at least five meters high so that there's a reasonable pressure for the taps and shower. We're going to make a spiral water pump to use the streams own current to pump the water up to the tank. A spiral pump is a water wheel that has a spiral of tube attached to the side so that it moves the water in a similar fashion to an Archimedean screw.
Generating power from the wheel
We have a fair bit of current in the river so we'll also try and use the water wheel to generate electricity probably using a cheap old car alternator and voltage regulator going to the charge controller of our solar setup.
