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.

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.

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 flowrate.- 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 ScheduleThis 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

ChallengesDesign:• 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
