Water Treatment


Fontana Water Company's goal is to provide the highest quality of water for its customers. In order to meet this goal, Fontana Water Company owns and operates three water treatment facilities, treating a combination of well and surface water.

Plant F10 - A 5000 gallon-per-minute (gpm) liquid phase Granular Activated Carbon (GAC) filtration system consisting of eight vessels to treat two wells for removing volatile organic compounds (VOCs) from the water down to non-detect levels.

Plant F17 - A 6000 gpm ion-exchange filtration system consisting of ten vessels in a lead-lag configuration to treat two wells for removing perchlorate from the water down to non-detect levels.

Sandhill Water Treatment Plant - A 20 million-gallon-per-day (mgd) surface water treatment plant consisting of diatomaceous earth filtration technology, treating Lytle Creek surface water and State Water Project water. The Sandhill plant is currently undergoing upgrades consisting of pre-treatment facilities (coagulation, sedimentation, and flocculation) and plant expansion with additional conventional filters that will increase the plant capacity up to 29 (mgd) and enhance the plant's ability to treat an additional amount of Lytle Creek water and State Water Project water.

Fontana Water Company plans to install additional treatment systems similar to the system at Plant F17 in order to utilize wells currently not in use. The cost of the treatment system at this plant will be partially funded by the Department of Defense.
