About Us
Our water specialists collect samples throughout the distribution system for testing at our advanced water quality laboratory, certified by the Environmental Lab Accreditation Program (ELAP). Our team of researchers, chemists, and microbiologists examine water for approximately 292 constituents using equipment capable of detecting levels as minute as one part per trillion.
To maintain ELAP certification, all scientists must complete annual blind-study proficiency tests for each water quality assessment performed. Test results are recorded in our Laboratory Information Management System (LIMS), sophisticated software enabling quick responses to water quality changes and trend analysis for effective future planning.
Cross-Connection Control Program
To preserve the quality of delivered water, Cal Water implements a comprehensive cross-connection control program. This crucial initiative ensures that activities on customer properties don't compromise the public water supply. Our specialists oversee annual testing of existing backflow prevention assemblies, assess non-residential connections, and manage installation of new commercial and residential assemblies. Last year, our team supervised installation of 2,826 new assemblies and testing of 36,433 backflow prevention devices company-wide.
Our customers serve as the first line of defense against system contamination from backflow. Even minor home improvements can create potentially hazardous situations, so adherence to plumbing codes is essential for community water safety. Please consult a qualified plumbing professional for any water-related modifications.
Common cross-connections include:
- Garden hoses attached without simple hose-type vacuum breakers (available at home improvement stores)
- Improperly installed toilet tank fill valves lacking required air gaps
- Landscape irrigation systems without proper backflow prevention assemblies on supply lines
