Slow Sand Filtration System–Village of Caprivi Heather Svec, Katie Thompson, Joey Bonavita, and Nate Lisbin Abstract and Problem Statement: The objective of the design project was to design a filtration system to provide Caprivi, Namibia with clean drinking water. In order, to provide clean drinking water for this village, we plan on implementing a slow sand filtration system. Our slow sand filtration system will cost less than $200 and the filter will be able o to be assembled in two days or less. We decided on a slow sand filtration method because it is the most effective filtering system. We have also decided to include an ultraviolet light in the holding tank to eliminate any microorganisms that could be possibly left in the water. With this filtering system, we will bring clean, uncontaminated water to the village of Caprivi, Namibia. Above is the cross section of our slow sand filter. We implemented a two tank filter system, consisting of gravel and sand. Above the sand is a diffuser so that the water can be spread evenly across the sand.

Connected by PVC pipe, the second tank is the moderator tank. The final tank is the holding tank where all of the filtered water is held. There is also a UV light in this tank to eliminate any left over microorganisms. TRIZ Contradiction and Solution Chart: TRIZ: Figure 5.1 Functional EMS Model
