16. Pre-existing Water Sources
Without Clean Water From Wells, Most People Get Their Water from
Holes in the Ground Shared with Animals

17. Gasoline Power Water Pumps
• Many wells pumps in the past have been
powered by gasoline powered generators
• These require money to buy gasoline, and
they are noisy

18. Solar Power as Solution
• Now solar can power the water pumps,
and eliminate the need to purchase fuel to
run a generator.

19. Steps of Installing a Solar Powered Well
#1. drill hole

20. #2. encase the hole

21. #3. cleanse well of silt and mud
by flushing with high pressure air

22. #4. form well cap for security

23. #5. connect hose, wires, & rope
to water pump, then lower pump into well
