Design of Sanitary Sewer and Storm Water Drainage Systems - Workshop
Fee: $2,415 / Online / Sep 14 - 16, 2026 / Course Code: 17-0924-ONL26
OVERVIEW
Please note, This instructor-led course has specific dates and times:
This course is held online over 3 days on the following schedule (All times in Eastern Time Zone): 10:00 am to 6:00 pm Eastern (Will include the usual breaks)
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.

INSTRUCTOR
Senior Project Manager | Water Resources
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.
