TRAINING.

Overview

After participating in this course, you will be able to:

• Analyze existing systems for any possible problems, maintenance and rehabilitation
• Recognize the numerous issues to consider when planning sewer and stormwater drainage systems at a given site
• Design sanitary sewer and stormwater drainage systems to meet given planning objectives

Description
Eighty percent of a municipality’s problems are caused by twenty percent of its sanitary sewers and stormwater drainage systems. The best way to avoid future problems is to pay greater attention to them during the design phase. This three-day workshop is aimed at those who want to hone their skills in sanitary sewer and stormwater drainage systems design, and stormwater management.

In a workshop setting, under the guidance of your instructor, you will complete a sanitary sewer and stormwater drainage system design and use a case study to discuss and develop a plan to mitigate the environmental impact caused by urban development and the management of stormwater.

Instructor

Nav Sandhu, P.Eng.

Nav is a Senior Water Resources Engineer with 20 years of experience.

He has extensive experience in stormwater management and drainage planning and design throughout Canada, ranging from servicing /planning studies to detailed design of complex systems. His stormwater infrastructure design experience includes storm sewer systems, culverts, above and below-ground detention and water quality facilities, diversion structures, control and outfall structures, infiltration systems, rip-rap protection works, and instream rehabilitation works. He’s also experienced in base-flow augmentation, source control/rainwater management and other LID systems-relatively new techniques that support sustainable design.

His stormwater engineering knowledge, municipal development, and highway experience make him an excellent resource for a range of clients. He has also provided expert opinions and reports on legal proceedings related to drainage throughout BC.
