The increasing degradation of the Reventazon River Basin, mainly through water pollution, was the reason for the establishment of the Committee for the Management and Planning of the Reventazon River Basin (COMCURE), who takes measures in its control and protection. The contamination of water promotes the proliferation of waterborne diseases, reduces the number of available water sources, raises the costs for supplying drinking water and is a threat to many species of flora and fauna.
The Municipality of Talcahuano, due to its geographic location, natural conditions and closeness to energy supply centres, such as coal from Lota and Coronel, had from the 50´s an important economic growth, a greater military presence, and an increased port capacity; all this led to an accelerated urban growth. The co-existence of active urban and industrial areas in an uneven territory, with abundant water bodies and a surface area of only 142.8 km2, have made the city specially sensitive to natural resource degradation. A situation was made critical and gave rise to the municipal strategy started in 1993. This situation was being aggravated by the chronic scarcity of resources in the Municipality and the lack of infrastructure and control mechanisms faced with environmental deterioration.
The Municipality, as the institution in charge of administering this serious environmental deterioration that affected the quality of life of its inhabitants, in co-ordination with other public, private and community organisations, manifest their outmost commitment and concern for decreasing water contamination. A program to appropriately zone the city in order to harmonise the different activities was implemented.
