Lake Titicaca, the highest navigable lake in the world (3.500m), is to be freed from contamination in an effort by its neighbouring countries Peru and Bolivia.
Bolivia is said to have already invested US$1.5 million in the construction of water treatment plants last year, now a clean-up project of both countries´ naval institutions have been confirmed.
Both Bolivia and Peru are to invest US$ 63 million during the first phase of the project in order to cleanse lake water by building sanitation services for the adjacent villages.
By this means the contamination by sewage is hoped to be avoided. In a further step, the countries want to reduce pollution from mining industry, livestock and agriculture.
