2. The Goal
The goal of this project was the design and
development of a water pump apparatus that
would be used as an educational exhibit in the OC
Great Park’s Farm & Food Lab.
As a secondary objective, this pump would
advertise a utilitarian pumping system that will be
developed for nations with water-pumping needs,
alleviating some of the hardships people must
endure in order to get the water they need.

3. Water Awareness - California
• 200 million acre- feet of water fall in CA/ year
▫ Over half soaks into ground/ evaporates/ used by
vegetation
▫ Leaves 86 million acre-feet of water for use
 48%- environmental uses
 41%- agriculture
 9%- cities & industries
 75% of CA’s available water occurs N. of Sacramento, while
80% of the demand occurs in the southern 2/3 of the state
*1 acre foot is 326,000 gallons- enough water for 2 families for a year

4. Water Awareness – CA Water Delivery
• Surface Water Projects
▫ Provide major portion of water
▫ 1000+ federal, state, local reservoirs & hundreds
of miles of canals and pipelines
▫ 2 major:
 Central Valley Project (CVP, federal)
 State Water Project (SWP, state)

5. Water Awareness - Key Water Projects
Water Projects Amount of Water
Central Valley Project 7 MAF- per year
State Water Project 2.3 MAF- per year
All- American Canal 3 MAF- per year
Colorado River Aqueduct 1.2 MAF-per year
Los Angeles Acqueduct 200,000 AF- per year
Mokelumne Aqueduct 364,000 AF- per year
San Francisco Hetch Hetchy Project 330,000 AF- per year

6. Water Awareness - CVP
• Begins in Cascade Mtn’s near
Redding, and goes down to near
Bakersfield
• 20 damns and reservoirs, 11
power plants, 500 miles of major
canals
• Manages 9 million acre-feet of
water
• 600,000 acre-feet for municipal
and industrial use ~1 million
households for a year
• 800,000 acre-feet/ year to fish
and wildlife; 410,000 acre- feet
to State and Federal wildlife
refuges and wetlands

8. Water Awareness - SWP
• Nation’s largest state built
system
• Water for 23 million &
755,000 acres of farmland
• Includes the 444 mile CA
aqueduct
▫ Delivers to San Joaquin
Valley, SF Bay, S. CA

10. Water Awareness - Irvine
• We get our water from 3 sources:
▫ State water project
▫ Colorado River
▫ Groundwater

11. Design Issue
• Main Issues
▫ Durability
 Frequency of maintenance?
 How long it would last?
▫ Accessibility
 Age and size?
 Handicap?
▫ Availability
 Off the shelf products?
▫ Ease of Manufacture
 Difficulty of assembly and fabrication
▫ Safety
 Does it satisfy safety regulations?

15. Bicycle System
• Two main design concerns:
▫ Drive Train
 Chain
 Belt
 Shaft
▫ Seat Configuration
 Upright
 recumbent

16. Shaft Drive
• Pros
 Safe
 Gears are enclosed
 No exposable moving parts
 Lower maintenance frequency
 Bevel gears protected from impacts/debris
 Durable
• Cons
 Heavier
 Inability to repair
 shaft must be replaced
 More expensive

17. Seat Selection
Recumbent
Pros:
• More comfortable
• Safer due to lower
center of gravity
Cons:
• Unable to shift weight
to balance
Upright
Pros:
• Commonly found
• Light-weight
• Can have multiple riding
positions
Cons:
• Uncomfortable over long
periods of time

19. Status at Midterm
• Had selected our final design
• Completed two proof of concept tests
Need to:
• Construct a final working prototype

20. Final Steps

21. Final Production Steps
• Detail components and materials for actual parts
sourced
• Fabricate prototype to verify design
• Analyze prototype performance
• Recommend design revisions

22. Final Product

23. Recommendations
• The use of components other than those used in our prototype is acceptable
and occasionally preferable (i.e. pump selection). Details of the final design
would be changed to account for this, but the fabricator judgment can
account for these variations. Details of our prototype design have been
included.
• Optimizing some features (e.g. seat geometry, pump selection) can only be
done with further iteration of the whole system, which we hadn’t the
resources for. A design that will last for years would call for this.
• The above holds true for exportable versions of this concept as well as they
would demand durability perhaps beyond even that required in a park full
of children.
