For years, Palmdale has complied with an important Regulatory Water Safety Compliance Program known as Cross-Connection Control. This web page serves to assist Palmdale Customers with their participation in this important safety program. The city has selected HydroCorp to assist with Coordination, Site Visits, and Data/Compliance Management.
This State Mandated Program focuses on non-residential (commercial) water service connections and onsite visual inspections to identify potentially harmful interconnections to the Palmdale CSD Public Water Supply.
The California Cross-Connection Control Policy Handbook requires water suppliers to undertake cross-connection control programs to protect the public water systems from pollution and contamination. This rule includes requirements for developing a written program, hazard assessments, regular testing of backflow prevention assemblies, and public education.

The anti-siphon fill valve device is located in the tank of your toilet. This device has a dual purpose: To fill the toilet and prevent backflow. This device must be placed at the proper height in order to insure that water from your toilet does not backflow into your drinking water. Proper placement is typically done during the installation process but can be easily overlooked. This device must be raised or the overflow pipe must be cut down in order to achieve a 1” air gap separation between the “critical level” of the assembly.

These require periodic performance testing by a Certified Tester.
