The Paranaíba River marks the border between the states of Goiás and Minas Gerais.

The Meia Ponte's basin furnishes water for 2 million people, fifty percent of the population of the state, and a large part of the economy depends on it.

A preliminary evaluation of water quality downstream from Goiânia indicates that the river has a stretch of 60 kilometers below Goiânia with low levels of dissolved oxygen and therefore a limited capacity to sustain aquatic life or provide conditions for agricultural activity.

In addition, the dry summers last up to six months, which means that the Meia Ponte cannot supply all the population that depends on its water.

Recently a project was initiated to try to recover this important river and a sewage treatment plant is under construction in Goiânia.
