Very Basic Question on Testing Potable Water Lines
Very Basic Question on Testing Potable Water Lines
(OP)
I have just a very basic question on tests run on potable water lines after repairs have been made. Among other things such as flushing and disinfecting lines you have to perform a hydrostatic test on the lines. This makes sense from an integrity view point because you want to ensure you're not losing water thus creating other problems. But in addition to that, does a leak represent a potential point of contamination? If so I assume it would have to be during a system pressure loss. Any general comments would be appreciated!
Thanks
Thanks

Anything that will delay returning a water line to service after fixing a leak is problematic from a customer service perspective. Admittedly, you want to ensure that the water does not have contamination. That is one of the reasons for maintaining a disinfection residual. The other thing that needs to take place is ensuring that the repair crew practices good protocol for keeping the area disinfected and disinfecting any parts that are used in the repair.

Policy for Determining When Loss of Positive Pressure Situations in the Distribution System Require One-Hour Reporting to the Department and Issuing Tier 1 Public Notification
It's 9 pages and the bulk of it deals with what they consider best management practices for main breaks that result in loss of positive pressure.
