To provide a simple sustainable technology with minimum operational cost to the underprivileged who have limited access to water and electricity and to people who care about the environment.
Through education and technology we endeavor to teach industry, analytical thinking and ingenuity, which could be considered building blocks upon which they could become self-sufficient to the point of creating revenues, which could then be used to reach out to other communities in need.
To create a grass-roots level organization that in due time could operate independent of outside support. We would want to see this organization utilizing technology fueled by natural energy from the sun, wind and water.
In 1999 we wanted to supply water to a children's home, located high up in the mountains of Northern Thailand. Initially, we deployed a conventional gasoline-powered water pump, which, quite predictably, proved to be by far too costly, both in running and maintenance terms.
We subsequently discovered the ram pump concept and purchased a number of commercially available units, some of which failed miserably to deliver water to our site 20 meters above and 800 meters away from a fresh-water stream. Hence, we decided to develop our own pump from standard fittings, including all kinds of check valves, in combination with various types of metal, PVC, PE & PU fittings, etc.
While we did experience that we could deliver sufficient water, there were a number of negative experiences:
1. High wear and tear of valves and system
2. Excessive noise
3. Inconsistent output
These challenges made us look into the ram pump technology in great detail, as the need to meet the children’s needs had created an obsession on our part; the time had come to ”master” ram pump technology. We began to research the principles of ram pumping technology, and built a test site that allowed us to change many parameters, including various high- and low-tech materials like Kevlar, nylon, Teflon, non-ferrous and ferrous steels and others. That was the time when Meribah Ram Pump becomes a social enterprice.
Our goal was to devise a long-lasting, virtually maintenance-free pump that could deliver a huge volume of water to a high elevation. The pump had to be constructed from heavy-duty material, yet still be affordable to people in resource-poor settings.
While we carried out tests on our prototypes, we discovered that all the aggregated information on ram pumps sourced from books and websites was either incomplete or simply failed to adequately explain the differing results observed. In the course of extensive empiric test series, we assessed the pumps under all kinds of conditions. We even ventured into quantum physics in an attempt to find possible answers to the results that could not be explained by existing mathematical concepts.
Over a period of 10 years of hands-on-experience, we invented our own unique valve technology, which had never before been used in ram pumps. Notwithstanding these significant advances, we are convinced that the ram pump technology is to experience further development and optimization.
We would therefore appreciate all input from others, regarding their own experiences with these pumps. Our core objective is to be able to provide the underprivileged people in rural areas with simple, robust and affordable water transport systems to free up valuable resources, eliminate the hazards of water contamination and diseases, and to improve standards of living.
