Water Sources and Uses
Nicaragua is a water-rich country with a water availability of 35,000 cubic meter/capita/year, corresponding to more than five times the average for Central America and the Caribbean. Less than 1% of these water resources is withdrawn for human use. The major water user is agriculture (84% of withdrawals), followed by domestic use (14%) and industry (2%).
Rainfall, while abundant, varies greatly. The Caribbean lowlands are the wettest section of Central America, receiving between 2,500 and 6,500 millimeters of rain annually. The western slopes of the central highlands and the Pacific lowlands receive considerably less annual rainfall. Mean annual precipitation for the rift valley and western slopes of the highlands ranges from 1,000 to 1,500 millimeters. Rainfall is seasonal—May through October is the rainy season, and December through April is the driest period.
Groundwater is the main source for municipal water supply in Nicaragua. For example, Managua - which is located on the shores of the polluted Lake Managua - is supplied entirely by groundwater, including by groundwater that infiltrates from the craters of volcanoes - called "lagoons'" within the city. For example, Asososca lagoon, to the west, is Managua's most important source of drinking water.

Famous quotes containing the words water and/or sources:
“Cities give not the human senses room enough. We go out daily and nightly to feed the eyes on the horizon, and require so much scope, just as we need water for our bath.”
—Ralph Waldo Emerson (1803–1882)
“On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.”
—Anthony Trollope (1815–1882)
