COURS.

APERÇU

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 & 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 & stormwater drainage systems design, & stormwater management.

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

Who Should Attend

FORMATEUR

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.
