South San Diego
South San Diego is a district within the City of San Diego, and is in the larger South Bay region of southwestern San Diego County, California. South San Diego is a practical exclave of San Diego, having no land connection with the rest of the city. It is the only part of the city which borders Mexico. South San Diego includes four of the city's official community planning areas: Otay Mesa, Otay Mesa-Nestor, San Ysidro, and the Tijuana River Valley. History Before the arrival of the Spanish explorers, area of South San Diego was inhabited by the Kumeyaay people. The Kumeyaay, also later known as the ''Diegueño'', traveled the region. This is evidenced by the shallow depressions in boulders that were used for grinding acorn into meal, that are found throughout the area. John J. Montgomery achieved the first controlled flight with a heavier-than-air flying machine in the United States when he successfully flew three glider aircraft designed in the period 1883-1886 from Otay Mes ...

Wastewater Treatment
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant. For domestic wastewater (also called municipal wastewater or sewage), the treatment plant is called a sewage treatment plant. For industrial wastewater, treatment either takes place in a separate industrial wastewater treatment plant, or in a sewage treatment plant (usually after some form of pre-treatment). Further types of wastewater treatment plants include agricultural wastewater treatment plants and leachate treatment plants. Processes commonly used in wastewater treatment include phase sepa ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Diego & Arizona Railway
The San Diego and Arizona Railway was a short line U.S. railroad founded by entrepreneur John D. Spreckels, and dubbed "The Impossible Railroad" by engineers of its day due to the immense logistical challenges involved. It linked San Diego, its western terminus, with El Centro, its eastern terminus, where passengers could connect with Southern Pacific's transcontinental lines, eliminating the need to first travel north via Los Angeles or Riverside. The company charter was executed on December 14, 1906, and the groundbreaking ceremony was held the following September. Numerous delays (including government intervention during World War I) delayed the completion of the line to November 15, 1919. Damage to the lines from both natural disasters and sabotage exerted great financial pressure on the company, and in 1932 Spreckels' heirs sold their interests in the railroad to the Southern Pacific, which was named the San Diego & Arizona Eastern Railway (SD&AE).

Savage Dam
Savage Dam is a dam across the Otay River in the San Ysidro Mountains of southwestern San Diego County, California. It is a concrete arch gravity structure high, and serves to store water from the San Diego Aqueduct's third pipeline for backup municipal uses in the San Diego metropolitan area. It is just over southeast of Chula Vista and north of the United States-Mexico border. The dam is named in honor of H. N. Savage, who directed its construction. The dam was originally completed in 1897 as an earthfill and steel structure called the Otay Dam by the Southern California Mountain Water Company to provide water storage. However, in 1916, heavy rains supposedly brought on by Charles Hatfield, a "rainmaker", hired by the city of San Diego to put an end to a drought, caused the dam to burst. The failure sent a wall of water high downstream, destroying buildings and bridges, and washing thousands of tons of sediment and wreckage into San Diego Bay. Eleven Japanese American farm ...

Charles Hatfield
Charles Mallory Hatfield (July 15, 1875January 12, 1958) was an American " rainmaker". Early life Hatfield was born in Fort Scott, Kansas on July 15, 1875. His family moved to Southern California in the 1880s. As an adult, he became a salesman for the New Home Sewing Machine Company. In 1904, he moved to Glendale, California. Career In his free time Hatfield studied pluviculture and began to develop his own methods for producing rain. By 1902 he had created a secret mixture of 23 chemicals in large galvanized evaporating tanks that, he claimed, attracted rain. Hatfield called himself a "moisture accelerator". In 1904, promoter Fred Binney began a public relations campaign for Hatfield. A number of Los Angeles ranchers saw his ads in newspapers and promised Hatfield $50 to produce rain. In February, Hatfield and his brother Paul built an evaporating tower at La Crescenta where Hatfield released his mixture into the air. Hatfield's attempt was apparently successful, so the ra ...
