Itaipu dedicates special care to the preservation of water, its main asset.

To protect it, the power plant maintains a watershed management program, whose purpose is to decrease the entry of sediments and chemical products into its reservoir.

According to the monitoring of the Paraná Environmental Institute (Instituto Ambiental do Paraná - IAP), the reservoir water at Itaipu is free from fecal coliforms and bacteria that could cause diseases in humans beings. According to IAP, there is no form of sewage emissions that may influence the quality of the water.

The concern for water quality led the company to create in 1977 a program for the permanent monitoring of the Paraná River and its tributaries, which contribute the water that feeds the Itaipu reservoir, formed in 1982.

The environmental programs developed by Itaipu have helped preserve the aquatic biodiversity and ensure its multiple applications without compromising the power plant's operations.

Maintaining the water quality includes soil conservation initiatives like the construction of large heaps on contour lines, adjustment of roads, maintenance of community supply stations, recycling of pesticide packages, and encouragement of direct planting, besides rural indoor plumbing systems.

The activities are developed with full support from the community: in all, there are 1,247 partner institutions among universities, organizations from various governmental spheres, NGOs and associations.

Itaipu water-oriented initiatives also aim to record the data obtained to create a scientific information bank and study the evolution of multiple parameters of scientific interest along the reservoir's working life.
