Central to the maintenance of human health is the supply of safe drinking water and the disposal of wastewater. Much of our water supply and water removal infrastructure is now in poor condition, and civil engineers and the society they serve face an increasing challenge to maintain these basic services. Aging infrastructure can however be renewed using “Trench less” techniques that minimize the disruption associated with trench excavation and buried pipe replacement. This course will focus on three technologies: pipe lining, pipe bursting, and horizontal directional drilling. While these operations are generally conducted by specialist contractors, the selection of the pipes to be installed depends on knowledge of the loads and load capacity of the pipe or pipe liner to be used. The course instructor builds of these three Trench less Technologies over the past decade. The important limit states for these systems are explained, methods of estimating pipe and soil response are outlined, and pipe and installation design procedures are explained.

Upon successful completion of this course, the delegates will be able to:

• Calculate length of pipe systems using the metric and inch system
• Calculate the Volume of cylindrical forms
• Interpret drawings to fabricate pipe systems
• Identify typically used materials, tools and equipment used in Pipe Fitting & Pipe Bending
• Identify common fittings, valves, pressure gauges, flow meters
• Know the common methods to fit pipes together
• Layout, cut thread and install pipes for water supply systems
• Know different possibilities on how to bend pipes (hydraulic pipe bender and hot bending)
• Know the basics about installing a building water supply system (circular pump, different valves, flow meter, pressure gauge etc.)

This course is suitable for consultants, municipal and transportation engineers, technologists and contractors in related industries.
