Types of Water Main Breaks

• Uncontrolled Outage• Loss of positive water

pressure in the potable water distribution system.

• Outage occurs before implementation of corrective action.

• Results in intermittent water service.


March 2017


• Controlled Outage• Partial loss of water pressure within

the water distribution system. • Positive water pressure is

maintained. • Requires a section of the water main

to be isolated and wholly/partially dewatered to facilitate repair.

• Due to implementation of corrective actions and not directly caused by the water main break.

March 2017


• Low Pressure Event• Positive pressure is maintained in

the water main during repair. • Water flows continuously. • It is unlikely the water main is

contaminated. • NJDEP/Customer/Boil Water

Advisory (BWA) notification and water quality testing are not required.


March 2017

Temporary Water Service

• Repair through the use of hydrant-to-hydrant connections• Dedicated for potable use only.• Must be ANSI/NSF 61 compliant.• Must be properly disinfected and flushed prior to use. Please note, the items listed above refer to the pipe/hose material.

• Failure to meet requirements will result in the issuance of the following:
