l Practical skills and familiarization with the equipment.

l The key features of the various categories of pipe sewer survey.

l How to recognise and code: structural conditions; service conditions; construction features; miscellaneous details from photographs and video.

l How to use the continuous defect facility for coding.

l Define typical drainage terminology

l Manipulate drainage gradient information

l Describe the basic principles of drainage bedding

l Explain the alternative access provisions

l Determine wastewater design flows

l Explain Basement pumping and anti-flooding considerations





This training course will combine presentations with instructor-guided interactive discussions between participants relating to their individual workplace. Practical exercises, video material and case studies aiming at stimulating these discussions and providing maximum benefit to the participants will support the training.

This interactive training course includes the following training methodologies as a percentage of the total tuition hours:

l 30% Lectures, Concepts, Role Play

l 30% Workshops & Work Presentations, Techniques

l 20% Based on Case Studies & Practical Exercises

l 20% Videos, Software & General Discussions

l Pre and Post Test





The course is designed for professionals involved in planning, design, construction, operation and maintenance and management of urban drainage and sewerage systems, as well as researchers and modelers in the field of urban drainage and sewerage
