​Course Duration: full work day, 7 hours
CEU Value: 0.7

​Learning Objectives: 

Students will learn that destructive forces can be generated as a result of the presence of air pockets, and that pipeline efficiency is greatly diminished if air is not purged effectively on an on-going basis. 

Trainees will become familiar with the many ways that air can be introduced to water pipelines. 

Trainees will learn that the water industry has only recently come to a better understanding of the formation and behaviour of air in water supply pipelines. 

The course will explain Boyle’s Law, Henry’s Law, and Charles’ Law, the 3 fundamental Gas Laws that govern 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.

The course introduces newer air management products, and examines operational procedures that can help minimize air accumulation in water systems.

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

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

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

Target Group: 

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