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.
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
