2. A Broken Jamaica? Words can have a powerful effect on the human mind, and when one hears the world “Jamaica” images of white sandy beaches form, because isn’t that paradise? These exclusive spots that reserve themselves for tourists only make up a small portion of the actual country. Jamaica is a third world country who has, since gaining its independence from Britain, undergone the ultimate transformation from a peace-bearing paradise to a country torn by poverty, war, and political factions rendering the country broken.

3. What’s our mission? The goal of this project was to generate a plan that improves upon the basic needs a rural community located in a third-world country. By taking advantage of both purification of existing water and various piping systems, the net water supply has increased for uses such as irrigation and self-sustainability.

11. Purification of the Water Water Purification: The water will come from two sources; (1) a nearby river and (2) rainwater that is collected in a tank. The water is pressurized by a shallow-well pump and is formed into the piping system with outdoor PVC piping. The particulates in the water are filtered with two conveniently named particulate filters in series that are rated 20 and 5 micron particle size. Sterilization of the water occurs via an Ultraviolet light that must minimally be capable of sterilizing water at 10 gallons per minute. (Fluorescent ultraviolet light rated at 9600 hours, about one year of continuous use). A screen must be placed over the rainwater tank and the wells distributed throughout the village to protect against various insects that could potentially contaminate the clean water.

14. Water Distribution As displayed via the 3D representation, the collected water from both the river and the rain is purified in the same area by the means described above. Pressure valves control the flow of water and distribute it accordingly through a system of underground pipes that lead (a) into the village and into wells and (b) into a specialized pipe system designated for irrigation. The wells provide the people with an outlet to obtain freshly cleaned water. The irrigation system consists of pipes that distribute water over a specific plot of land where villagers may grow their crops for food.
