From: State of water resources in Cuba, National Institute of Water Resources, 2005, Cuba
The indicators achieved in these important services to the population, today are a imposssible dream for the South countries, and for 30-50% of the population in many countries. The work done in Cuba can provide water supply coverage to 95% of the population and the sanitation to 94.3%. This coverage is achieved by supplying 1 705 hm 3 of water through nearly 19 000 km of pipes and conduits and 2.6 million household connections, and further purification was subjected to 97.4% of total water supplied. Chlorination reaches 99%. The country has 875 aqueducts in urban areas and 1 849 in the rural sector.
Places with sewage service amounted to 559, and provide coverage to nearly five million people in the urban sector, and one million in rural areas. The wastewater is discharged through pipe 5 000 km and reach the 592 hm 3, of which 50% received clearance treatment in 10 water treatment plants and 564 oxidation ponds. In these activities deserve noted the work and results achieved during the economic crisis of the nineties. During this period ended, modernized or expanded major works (dams, conduits, water treatment plants, networks, outfalls, etc..), Which significantly increase the number of new users and improve the supply to others.
To cite a few examples can be noted the modernization and expansion of water supply in the capital, the solution to the partial or total supply in the cities of Manzanillo, Cabaiguán, Santiago de Cuba, Guantanamo, and the important works that today are performed in the dry affecting the cities of Holguin, Camaguey and Las Tunas. Very important are also the new aqueducts to accommodate the development of tourism in Cayo Coco, Cayo Largo, Cayo Coco, Santa Lucia and tourist areas in the provinces of Holguín and Santa Clara, among others.
Of all the effort after the nineties, the most impressive for its social impact is the development of Rural Water Supply Programme. Until the end of 2001 were built 3 220 rural water supply, benefiting nearly two million people. In mountain areas in the Turquino Plan, from 1996 to 2001, 426 built aqueducts, which have benefited over one hundred and eighty-two thousand people, raising their quality of life and enables their stay in these areas to secure important items of the economy, such as coffee and cocoa production, forestry, environmental protection, flora and fauna.
