Problem Statement One of the biggest problems facing Guatemala is a shortage of clean potable water available to its citizens, especially those living in rural villages.

Overview Updated Marketing Research Design Business Strategies Goals and Concerns

Marketing Research Current Water supply –Water in Pasajquim is free. –The water in Pasajquim comes from two different natural sources. The water travels through different pipes. –In the first section, the pipes are galvanized, and then the water goes through PVC pipes until it gets to the village water tank. –The tank is made out of concrete and it is located in the higher area of Pasajquim. –The tank is cleaned once or twice a year. –The water goes down the hills by gravity to the houses and gardens. –The water never goes through a filtration process.

Management of water –Majority of people uses the water directly from the faucet. –A few percentage boils the water to drink. –The majority feels the water from the faucet is clean. –People in Pasajquim don’t associate diseases with the fact that they drink unpurified water. –Nevertheless, in a survey, 100% of the people showed interest in having a filtration system in their houses.

Uses of water in Pasajquim –Each person drinks an average of 5 cups/day –They use this water to shower, to wash their cloth, plates, pots, and every thing in the kitchen, to brush their teeth, and to water the plants. Diseases as a result of the use of unpurified water –There are many diseases that come along when people use unpurified water: diarrhea, cholera, amebas, and intestinal infections.

Filter Ideations

Filter System Process

General Considerations A. Replaceable - Easily replaceable by accessible components. - Filtering materials will be replaced after approximately three months. - User-friendly. - Estimated duration time will be 5 minutes. - Easily found in common stores. -The location of the filter house should be easily identified. - Prevent water leaking. B. Flow rate - Fill a cup of water in 10 seconds (~ 1 oz/s). - The pressure from the faucet will facilitate the necessary flow rate. - Filter dimensions will be controlled in order to fulfill the customer satisfying flow-rate conditions.

Filter Design - PVC Materials I. Faucet Connector - O-ring protects leakage. - Scrolls onto faucet. II. Filter Housing - Scrolls onto connector. - Polypropylene in both ends. III. Output - Connects to filter housing. - Controls flow rate. - Faucet is on. -O-ring protects leakage.

Business Strategies Tying service to product Modular product – one-time investment filter housing, cheap replaceable filters Easy to create business Service – manufacturing, maintaining, and replacing filters

Business Strategies Business Plan 1 Create rural manufacturing business to sell filter housing -If our design is simple enough, uses cheap enough materials, and requires very little construction expertise, this business plan will be perfect. Sustainable rural business is one that grows the bio-filter material and maintains/ replaces filters Consumers pay subscription fee for service

Business Strategies Business Plan 1.5 Pre-established manufacturing business sells filter housing Same filter manufacturing, maintenance, and replacement business Consumers pay subscription fee for filter replacement service.

Final Schedule This Week (11/11 – 11/15): Decide on materials for major design components. Create detailed drawings for all the components and their interactions. Follow up with our contacts and receive more primary research (lab data). Next Week (11/16 – 11/22): Order necessary parts for prototype (version 1) Choose a filtration method and work out necessities (e.g. materials) for method Finalize business strategies and write them up.

Week (11/23 – 11/29): Finish prototype (version 1) Start testing with dirty water samples and gathering results Make any necessary changes, update prototype Week (11/30 – 12/7): Write up findings and finalize working prototype Work on product presentation (e.g. posters, promotional material) FINAL (12/8): Present findings and demonstrate working prototype

Challenges Design: How to handle pressure buildup (good gasket design) Assuring a reasonable flow rate for drinking water Cost of material per unit Making a quick prototype for immediate testing Teamwork: Smooth communication Ensuring that everyone manages their time to finish their assignments

Overcoming Challenges Design: Discuss each design issue as a team Organize costs of each design Be practical and organized with the prototype design Teamwork: Keep communication strong through consistent meetings Devote extra hours to prototype Refer to team rules if issues arise
