Green Waters of Lake Managua, Nicaragua12.3N 86.3W
The green lake visible southeast of the Gulf of Fonseca is Lake Managua, in Nicaragua, one of Central America’s largest fresh water reservoirs. A new water treatment plant is purifying the polluted lake, helping residents.
For decades, household sewage and industrial effluents generated by residents and farmers in northern Nicaragua ended up unfiltered in Lake Managua. The result was an epidemic of water-transmitted infections and toxins in the lake’s fish. The contaminated lake posed a health hazard to people living along its shores, who depend on its water to cook, drink and wash.
Now, a water treatment plant installed on the shores of the lake has begun cleaning up the waste water and supplying fresh, drinking water. Experts are also working on using the abundant dried sewage sludge as an alternative to synthetic fertilizers. The aim is to save money, slash carbon emissions and help restore the lake’s strained ecosystem (click here for more information).
