A pressure surge, also known as a transient event, occurs in the distribution during a rapid change in normal operations, including:

  • Booster pump or supply well sudden shut-down, or booster pump / supply well sudden restart
  • Valve closing or opening
  • Rapid opening of fire hydrants

These events may be the consequence of either power failure or equipment failure, or other operator errors. When they happen, these events may cause pipeline failures in the distribution system.

Akel Engineering Group work with distribution system operators and successfully track historical incidents and identifying if they were caused by a surge or other system condition.

We recommend realistic mitigation measures, including surge suppression devices, to improve system operations.
