What is water? Why is it important in our daily lives?

by The Brazos River Authority

Water is a substance that is essential for the survival of all known forms of life. It covers more than 70 percent of the Earth’s surface, though much of that water is too salty for consumption without treatment.

On a molecular level, water is a mixture of hydrogen and two oxygen atoms, and is found most often as a liquid. Below 32 degrees Fahrenheit or 0 degrees Celsius, it becomes a solid, in the form of ice. At its boiling point, water becomes a gas or vapor.

Though the Earth’s population continues to grow, water is a finite resource. Planning for the development of additional potable water sources through new treatment technologies or through conservation efforts will be essential to our future.

About us

The Brazos River Authority was created by the Texas Legislature in 1929 as the first state agency in the country with the purpose of developing and managing the water resources of an entire river basin. Today, the Authority develops and distributes water supplies, provides water and wastewater treatment, monitors water quality, and pursues water conservation through public education programs. Although the Authority is an agency of the state, it does not levy or collect taxes and is entirely self-supporting.

The information provided on this site is intended as background on water within the Brazos River basin. There should be no expectation that this information is all encompassing, complete or in any way examines every aspect of this very complex natural resource.

We invite you to post comments and expect they will be made in good taste. The Authority reserves the right to reject or remove any comment that is not constructive in the education of the general public on issues regarding water in the Brazos basin.
