1. What does a Water Quality Control Facility (WQCF) do?

A WQCF (also called a wastewater treatment plan) removes impurities contained in wastewater. This treated water can then be safely discharged to the environment. This same process occurs in nature. Treatment plants enhance this natural process and speed it up to treat larger volumes of wastewater in a shorter period of time. Treatment includes chemical, physical and biological processes to reclaim the water.

2. Are Wastewater Treatment Plants really necessary?

Yes! Modern wastewater treatment plants are critical to a safer, cleaner environment by reducing the organic load and controlling bacteria and waterborne diseases.

3. Where is Patterson’s WQCF located?

Our plant is located at the end of Walnut Avenue near the San Joaquin River. If you are interested in taking a tour of the plant, please see the quick links to request a tour.

4. Where does the water go once it is treated at the WQCF?

The treated water is discharged to one of fifteen evaporation and percolation ponds for disposal. These ponds have a combined total area of more than 100 acres.
