Abstract: We propose an alternative solution to the problem of the communities which are currently faced in the remotes area of Timór-Lorosa’e. To access for water and sanitation, people need to walk at least 2km away. Introducing a ram pump system can be one of great solutions. Delivering water from water sources at bottom to the top hill to reach community as a final user by using this system. As a testing performance, the pump was installed in the laboratory level at the Mechanical Engineering Department, and it was also tested in the field at Aldeia Ailuli, Sucu Lete-Foho, Postu-Administrativu Same, Munisipiu Manufahi. In this research, 6 different capacity of air vessel were analyzed for comparing the operational conditions at locations. It is concluded that the air vessel with volume capacity 4558055 mm³ (4.6 litter) has higher delivered efficiency (η = 80 %) at laboratory. The results of the field test at Ulurba, Lete-Foho, Aldeia Ailuli, Manufahi Municipal show that the pump capacity is reached at 15m with water flow rate 5 liters/m.
