One of our neighbors uses water from a small stream to water his garden and lawn. He uses a pump very similar to the self priming pumps used for pools and hot tubs. You can install a filter on the discharge and provide all the water you might need. Just be sure the filter is really more like a strainer than a true filter. A true filter will plug up too often to be practical. You can watch videos about www.wegotpumps.com by clicking the link. They are a great source for water pumps.
