3.042 Materials Project Laboratory Project Concept and Plan

This project aims to address water contamination in developing countries by providing low-cost water tap solutions for safe storage. Lack of access to clean water is a significant problem leading to millions of deaths, especially in children. By utilizing durable materials like clay, plants, and synthetic plastics, alongside versatile tap attachment methods, we design affordable water taps to ensure safe water containers. Our team's project concept and plan focus on economic efficiency, local materials availability, ease of processing, and user-friendliness. Join our mission to combat water contamination and improve water access globally.

  2. The Problem of Water Contamination • According to the CDC, Center for Disease Control • http://www.cdc.gov/safewater/about_pages/about_who.htm • 2-3 million children < 5 yrs old die of diarrhea diseases • Water sources: • Surface water sources such as rivers or lakes   • Groundwater wells that are potentially contaminated, particularly open shallow wells   • Piped systems in which the water is inadequately treated or flow is intermittent, allowing contamination through leaks where pipes are connected   • Piped water systems in which intermittent flow requires households to store water   • Water tankers   • Water vendors whose source of water is not safe or whose tanker or storage tank is not likely to be clean

  3. Lack of access to safe water • Population shifts stress water & sanitation infrastructure due to natural disasters, armed conflicts, etc. • Chlorine effectively inactivates the majority of organisms that cause diarrhea disease in humans • Safe containers for storing water an issue; need cheaper taps to use for variety of storage canisters

  4. CDC safe water vessel • Produce in South Africa US $2.50 • To purchase & ship to Zambia from South Africa, costs US $5 • In India costs US$2 to produce & ship within country • To make vessels locally, molds for vessel, spigot, & cap US $15,000
