Learning Objectives:

Students will learn that destructive forces can be generated as a result of the presence of pressurized air pockets in distribution piping.

Trainees will learn how pipeline transmission efficiency is greatly diminished if air is not purged effectively on an on-going basis.

The course enables trainees to understand how air can accumulate in any type or size of water main. The course will explain Boyle’s Law, the Gas Law governing how air behaves in a pressurized piping system.

A detailed examination is provided of older air valve designs, to highlight performance deficiencies that can affect the draining and filling of pipelines.

A collection of air valve demonstrators, of varying technologies, is made available for hands-on trainee examination.

A number of related videos are embedded into the presentation to support trainee understanding of the phenomenon of air/water interface.

Trainees and the client utility will be supplied, and taught, a comprehensive air valve inspection procedure that can serve as a suitable Standard Operating Procedure for this pipeline component.

Target Group: 

Water distribution management and field staff, roster contractors, consultants, water utility construction inspectors, water system designers
