All water lines and services shall be hydrostatically tested to conform to AWWA C-600 (latest version).  The PSU hydrostatic testing plan must be submitted to and approved by PSU Engineering Services’ Utility Systems Engineer –  Water.  PSU Water Services (for University Park Projects) and PSU Engineering Services’ Utility Systems Engineer –  Water shall be notified of the testing a minimum of three (3) business days prior to the testing to allow scheduling for observation of the testing.  At University Park, all hydrostatic tests must be observed and approved by PSU Water Services personnel.  At locations other than University Park Campus, all hydrostatic tests must be observed and approved by  PSU Engineering Services’ Utility Systems Engineer – Water.
2. Disinfection shall conform to AWWA C-651 (latest version).   The disinfection plan must be submitted to and approved by PSU Engineering Services’ Utility Systems Engineer –  Water.    The University shall retain the services of a PA DEP certified water testing laboratory to analyze  the potable water samples .  The water line must be thoroughly flushed after disinfection and achieve ambient free chlorine residual concentrations prior to collecting the sample. PSU Water Services shall be notified of the testing a minimum of three (3) business days prior to the testing to allow scheduling for observation of the testing and perform chlorine residual testing.  At University  Park, all flushing and sampling/field tests must be performed by PSU Water Service Personnel.  At locations other than University Park Campus, all flushing shall be performed by University Personnel and sampling/field tests must be performed by the PSU Engineering Services’ Utility Systems Engineer – Water .  All test results shall be provided to Engineering Services prior to activation of services by PSU Water Services at University Park or University Personnel at other locations.
3. At University Park, meter and backflow prevention device(s) shall be inspected and tested by PSU Water Services prior to service activation by PSU Water Services.  At locations other than University Park, meters and backflow prevention device(s) shall be inspected and tested by properly certified backflow preventer technician prior to service activation, and the testing report sent to the PSU Engineering Services’ Utility Systems Engineer – Water.
