How does a hydraulic ram pump work to efficiently lift water to a higher elevation?

A hydraulic ram pump uses the force of flowing water to pump a smaller amount of water to a higher elevation. When water flows into the pump, it creates pressure that closes a valve, forcing water into a chamber. The pressure builds up until it opens a second valve, allowing the water to be pushed up to a higher level. This process repeats, using the energy from the flowing water to lift water to a higher elevation without needing electricity.
