The Acueducto de Albear (Albear Aqueduct) is the name of a water supply system of the city of Havana, Cuba built in the 19th century by Francisco de Albear. ==Background== At the beginning of the 19th century, the city of Havana, Cuba started to feel a severe shortage of drinking water. After having negotiated with several French engineers, in 1852, the Governor of Cuba José Gutiérrez de la Concha, decided to create a commission to propose solutions for the water supply of the city. The commission was to be chaired by Francisco de Albear, at that time colonel of the Corps of Engineers of the Spanish army and chairman of the Public Works Committee of Cuba. His main assistant was José Luis Casaseca, Director of the Institute of Chemical Investigations of Havana. The construction of a new water supply system was a necessity for the improvement of the sanitary conditions of the city. There had been severe outbreaks of cholera in 1850, 1856, 1865 and 1867-1870. The mortality due to disentery and other waterborne diseases was also high. The investigations carried out by De Albear’s team were extensive. He investigated various alternatives among which the use of the Luyanó, Martín Pérez, Guasabacoa, Marianao or Almendares rivers as well of the Cacahual or del Calvario springs, all of which he rejected for various reasons. He finally settled for the use of the del Vento springs, both due to the superior water quality and for the possibility of conveying the water by gravity, the source being located 41 m higher than the city. Chemical studies carried out by José Luis Casaseca lead to the conclusion that the water of the del Vento springs had to be isolated from the Almendares River, to prevent a deterioration of the water quality, which was of great concern, due to the tropical location of the island.〔José Luis Casaseca,: ''Informe sobre los análisis de las aguas del Almendares y de Vento'' – In: ''Memoria sobre el Proyecto de conducción a la Habana de las aguas de los manantiales de Vento'' Imprenta del Gobierno y Capitanía General por S. M., Habana, 1856〕 However, it was only in 1855,that a second commission, chaired also by Francisco de Albear, started extensive geological and hydrological field surveys, to ascertain that the springs had the capacity to cover the water requirements of the city. Finally, on November 25, 1855 De Albear was able to present his report to Governor José Gutiérrez de la Concha.〔Francisco de Alvear y Lara – ''Memoria sobre el proyecto de conducción a La Habana de las aguas de los manantiales de Vento. Formado de orden del Exmo. Sr. Governador Capitán General de la Isla de Cuba, D. José Gutiérrez de la Concha, por la Comisión encargada del estudio para abastecer de agua potable a La Habana.'' - La Habana: Imprenta del Gobierno y Capitanía General, 1856.〕 Copies of the report were sent to the Ministers of Interior (Ministro de Gobernación) and of Public Works (Ministro de Fomento) in Madrid. The "Royal Decree for the conveyance of the water of the Vento springs to Havana" was signed on October 5, 1858. To ensure the financing, the decree suspended for three years all payments from the revenue generated by the Fernando II acqueduct, imposed an annual fee of 45 pesos for each water faucet and authorized the governorship to raise another 500,000 pesos through taxes, if necessary. On February 18, 1859 Governor Gutiérrez de la Concha created the Administration of the de Vento canal, Board of Directors 〔Rolando García Blanco - ''Agua, medio ambiente y sociedad en La Habana colonial'' – CubaLiteraria ()〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acueducto de Albear」の詳細全文を読む スポンサード リンク
