SAWS Cross-Connection Control and Backflow Prevention Program
The goals of SAWS Cross-Connection Control Backflow Prevention Program are to safeguard public drinking water and protect the health of our customers by maintaining a high level of backflow prevention and cross-connection control.

Cross-Connection Control and Backflow Prevention Program
To protect the water system, backflow prevention assemblies (devices that prevent the backflow of water) are required for all connections that may present a potential source of contamination of the public water system. There are two kinds of assemblies installed:
- External backflow assemblies are used to protect the public water system from possible contamination resulting from the customer's premises.
- Internal backflow assemblies are used to protect the customers from potentially hazardous cross connections within their own drinking water system.
Backflow Prevention Assemblies used to protect the public water system
To keep the drinking water safe, SAWS reviews and stamps the utility plans of each new customer for compliance with cross-connection control/backflow prevention requirements. SAWS inspects the installation, repair or replacement of external backflow prevention assemblies, and monitors and enforces the annual testing requirements for those assemblies.
Backflow Prevention Assemblies used to protect the customer's drinking water system
Intitial permitting and inspection for backflow assemblies, including new installations, repairs and replacements, are administered through the City of San Antonio Development Services Department, 1901 S. Alamo, 210-207-1111.
SAWS will monitor and enforce the annual testing requirements for backflow prevention assemblies.
