Case for Cambodia


The goal of this team is to create a master plan for the Eden School of Agriculture (ESA). This master plan will include the steps to develop ESA’s farm land into a center of education for the Cambodian farmer and tourists visiting the farm.  The master plan will include a design of a multipurpose building, water distribution system, energy source from either solar or hydro, a bridge, and sanitary facilities. There will be a focus on using the local building techniques and materials to design a durable facility. Our team will focus on designing a system that is low cost considering the average Cambodian only makes around $500/yr. This plan will be designed to integrate its components together as well as have the ability to be built in stages as money is raised.

Common Building

In order to host visitors, teach classes, gather, cook, and for many other purposes, a building needs to be erected that can function for all purposes. The structure will be 12 meters wide by 16 meters long and two stories, built in the local Cambodian style. The first level will remain mostly open area, with one enclosed classroom, a kitchen, three bathrooms with showers, and a stairway to the second level. The second level will consist of a hallway opening into many dorm rooms for large groups (such as Calvin interim groups) to stay in. Electricity will be provided by solar panels located on the roof of the building, and a possible future computer lab will also be powered by the solar system.

Some examples of Cambodian Buildings

Sanitary Facility

The sanitary facilities will consist of three bathrooms and will be included in the common building. Each bathroom will have a toilet, sink and shower area. The water will be provided to all three from either the well, or from the nearby stream. If provided from the well, it is the goal to make it a gravity fed system. On the other hand, if water is provided from the stream at the first dam, it may have to be pumped due to elevation differences. The full dimension for the three bathrooms is 3 x 4.5 meters and they will be in series on the side of the common building. The sink, shower, and toilet will be combined with the kitchen water and be transported to a standard septic system. Considering the size of the dorm, the effluent will go to two septic systems in series. From these, a drainage field will be large enough to provide adequate removal of the waste for the whole dorm.

Dam and Bridge

In order to cross from the current site to the new development a bridge will be necessary. The design will call for a dam, that will help back up the stream during the dry season, and a land bridge on top of the dam that will be used for walking and transporting farm equipment. The land bridge will need to have culverts underneath between the bottom of the bridge and the top of the dam. These culverts will handle the increased flow during the wet season and will allow for water to flow under the bridge keeping it usable year round. The end design will call for a bridge that will need to span over a 14 meter wide stream.


A drip irrigation system to their vegetable garden will provide the crops with adequate hydration during the dry system. This system is the most efficient use of water, which is important for this region. The water used for the irrigation will be pumped from the fish ponds and will provide a great source of nutrients to the plants.


Solar Energy

Solar was selected because it is the most viable option due to the schools remote location and Cambodian climate (rainy season).  In order to provide adequate power for the area, it is most likely that two separate systems will be developed. The first will provide the necessary power to operate the pump at the well. Providing consistent and reliable power to the pump will be an improvement to the current system and will increase the lifespan of the pump. The second system will provide for the electrical needs of the new ESA common building which is also in the design phase.
