The EMAS pump is a very cheap PVC piston pump for family use, which can both pump water from a well and pump it to an elevated point. For example, it can pump water from 20 meters underground directly to an elevated tank another 20 meters above the ground level. The ability to pump directly to a storage tank avoids handling of the water, which avoids contamination.

 

The EMAS pump compresses water between two one-way valves (check valves produced with glass marbles), a footvalve and a piston valve. Water is forced up the piston tube and comes out of the pump handle.

 

In many rural areas, people collect water used for domestic purposes from a central water source. These can be very far away from home, therefore collecting water takes up much time and energy on a daily basis. It is much more convenient to at least connect a distant pump to a local faucet for water in the kitchen, and if possible also for a shower. It also encourages better personal and domestic hygiene. This is possible using the EMAS pump, since it ejects water with the necessary pressure to transport it from its source up to an elevated distribution tank.
