*A man, a plan, a canal; Panama*<br />*The Panama Canal was the largest single project undertaken.<br />*The project began on the 1880’s<br />*People wanted to connect the Atlantic Ocean and Pacific Oceans to find a shorter route.<br />*The design was thought on water elevators.<br />*The canal was the success that remarked the era.<br />*The French were the Pioneers of this construction in 1879.<br />*Ferdinand de Lesseps from France an engineer of 74 years was the only person able to build this canal.<br />*He first traveled to Panama and observed the working area.<br />*They cleared the jungle by hand, made calculations and then the digging began.<br />*Many people died for food poisoning, snake bite, typhoid and yellow fever (malaria).<br />
*A man, a plan, a canal; Panama*<br />*French engineers worked on their own way.<br />*They remained 10 years in Panama building the Canal, they lost around 20,000 men and then they run out of money.<br />*It was impossible to keep working, they thought they wasted life, time, and money. But they didn’t know they just had to wait a little bit longer for technology to come and help.<br />*They left and then years later the turn of The Builders (Americans) arrived.<br />*President of the U.S. Theodore Roosevelt was in charge in 1901, when William McKinley was assassinated.<br />*He thought it was important sea power and the command of it, that’s why he supported the construction of Panama Canal.<br />*In 1903 was the Panama Revolution.<br />*On November 18, 1903 Secretary John and Bruno Burela signed a treaty. <br />*With 10 million dollars, the United States was in power to build the Canal.<br />
*A man, a plan, a canal; Panama*<br />*The construction began one more time, but the yellow fever killed many people again.<br />*This time the project was on the hands of new engineer John Stevens.<br />*He first wanted to clean everything to avoid mosquitoes and yellow fever afterwards. By 1905 there were no more yellow fever and the living conditions changed dramatically.<br />*Railroads played an important role during this time too.<br />*With the construction of the Panama Canal, they created the largest men-made lake in the world.*Roosevelt traveled to Panama for the first time and observed the progress made.<br />*After John Stevens quit, George Washington Goethals took the power.<br />*Workers arrived by sea and they were paid 10 Cents per hour, 10hrs per day, 6 days per week.<br />*Working conditions were dangerous.<br />
*A man, a plan, a canal; Panama*<br />*By 1912 there were more than 50,000 workers in the Panama Canal.<br />*The Canal provided its own power, it works because the supply of water from the rain forest is never ending.<br />*For the years coming up, the canal became a big attraction for tourists.<br />*The Great opening was August 15, 1914.<br />*The approximate total costs of it was: 352 million dollars, the French and American total expenses was of 639 million dollars.<br />*50 miles crossing takes about 9 hours.<br />*”The canal remains the busiest sea land in the world, it carries crude oil, Italian marble, coffee and bananas among some other things.” <br />*The Canal belongs to Panama buy the United States have the permanent right to protect and defend the neutrality of it.<br />*President Theodore Roosevelt never saw the canal finished.<br />*Science and technology made history one more time by helping out on the construction of this important canal.<br />
*Los Angeles aqueduct*<br />*In 1913 the City of Los Angeles completed the construction of the first aqueduct.<br />*In 1902 Los Angeles purchased the Los Angeles City Water Company for $2 million dollars.<br />*William Mulholland was the superintendent of this company and was in charge for many years.<br />*“The 11 families who founded El Pueblo de NuestraSeñora La Reina de Los Angeles constructed the city’s first water system”<br />*Mulholland watched the effect of Los Angeles growth for many years.<br />*He was concerned about the usage and administration of water, so he made some changes to save more water.<br />*In order to have more water, he began to search a new supply of water<br />*Fred Eaton and Joseph Barlow Lippincott played an important role too.<br />
*Los Angeles aqueduct*<br />*Fred Eaton convinced William Mulholland that the Owens River would provide Los Angeles with water.<br />*Mulholland estimated that the cost of the project would be $25 million dollars.<br />*They needed community support.<br />*They presented an application to build the aqueduct on May 13th.<br />*By June 30th 1906 Los Angeles obtained permission to start working on this dreamed project.<br />*This was a good paying job and many people from many different nationalities such as Greeks, Serbs, and Mexicans contributed on the construction of the aqueduct.<br />*They obtained shelter, food and medical care.<br />*Medical director of this project was Dr. Raymond C. Taylor.<br />
*Los Angeles aqueduct*<br />*Later on Los Angeles obtained water form Owens River, Colorado River, Mono Lake’s Seven Tributary Streams, and Haiwee Reservoir.<br />*But they faced another problem when Owens Valley population began to dispute their water.<br />*Los Angeles Aqueduct was limited<br />*The Second Aqueduct of Los Angeles was finished in 1870 with a total amount of $89 million dollars, and it is said it was much easier to build due to improved construction equipment.<br />*Both of the Los Angeles Aqueducts deliver an average of 430 million gallons per day<br />
*Los Angeles aqueduct*<br />*The growing population of Los Angeles is a concern for the adequacy of supply.<br />*Now, there is a new focus on the administration of water.<br />*“There are 3 sources for Los Angeles’ water: approximately 60% comes from the Los Angeles Aqueduct system, 15% from the San Fernando groundwater basin, and 25% from the Metropolitan Water District’s Colorado and Feather River supplies.”<br />*Los Angeles has become the nation’s second largest city.<br />*Creation of new better conservation measures.<br />*Public information and school education programs to promote conservation of water.<br />
