A Natural Solution
Water is one of our most important natural resources. Oceans, lakes, rivers, streams, and ponds cover well over 70 percent of the earth's surface. It's part of every living thing.
All of us depend upon water for survival. We use it for drinking, cooking, bathing, irrigation, farming, industry, travel, and recreation. In fact, there isn't a day that goes by that any one of us can go without water.

The Central Valley Water Reclamation Facility treats millions of gallons of wastewater a day and returns them safely to the environment.
Yet, the actual supply of clean fresh water is limited. It comprises only 3 percent of the world's entire water supply. And every time we use it, we pollute it. It becomes used water - what we call wastewater - contaminated with human waste, paper products and other trash, hair, bacteria, salts, soaps, personal care products, foods, oils, chemicals, and more. If returned to our waterways untreated, this contaminated water would harm fish, plants and wildlife, and spread diseases. Eventually, it would harm all of us.
When untreated wastewater enters our rivers, lakes and streams, the organic pollutants decompose and consume the dissolve oxygen in the water that is necessary to support fish and other aquatic organisms. In addition, wastewater can contain a multitude of different compounds such as ammonia which are toxic to aquatic organisms. When small amounts of wastewater pollute waterways, nature's own microorganisms purify the water by consuming the organic wastes and restoring the oxygen balance. These microorganisms also detoxify the wastewater by breaking down the ammonia and other toxic compounds.
However, when large amounts of pollution occur, the natural water purification process is overwhelmed and Mother Nature is at a loss to restore the balance. It is then up to us to give a helping hand, and that is what the Central Valley Water Reclamation Facility is designed to do. Central Valley uses several natural biological treatment processes for treating both the water and solids. These processes are engineered to mimic, but speed up, the natural purification processes found in lakes, rivers and streams.
