The basic idea behind a ram pump is simple. The pump uses the momentum of a relatively large amount of moving water to pump a relatively small amount of water uphill. The pump has a valve that allows water to flow through this pipe and build up speed. Once the water reaches its maximum speed, this valve slams shut.
Depending on the drop and the lift, ram pumps will work on sites with 3 to 50 feet (0.9–15 m) of head (vertical drop) and can deliver to elevated sites far from the pump and source.
Considering a minimal amount of water supplied from a spring or river; 30 liter per minute down the drive pipe can deliver, through an Evergreen Gravity Pump, 10 liter per minute with a head of over 80 meter at a distance of 1 kilometer away.

With this in mind the use of renewable energy of water from the source ensures NO running costs and NO environmental impact.
- Simplicity and reliability guarantees a minimal maintenance program.
- Monitored irrigation in the rural areas will allow individual farmers to enrich their crops and provide for their families and for sale
- Filtration systems can be put in place for drinking depending on the water source, farming methods can be taught in the rural areas by the team.
