Cross Connection and Backflow Prevention
All backflow prevention assemblies will need to be tested by a certified backflow
assembly tester annually and a copy of the test results mailed to PWSSP.  It will be
the responsibility of the owner/operator to ensure that testing is conducted annually
and the results reported to the PWSSP.  PWSSP may inspect these devices and
request to view the test results during a sanitary survey inspection.
