Stormwater Management - Design, Inspection and Operation/Maintenance of Stormwater Control Facilities
Dec 1 - 2, 2022 /
Course Code: 13-1219-ONL22
This course is held online over 2 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:
- examine design applications in new and existing developments
- apply emerging techniques for stormwater quantity, quality and erosion control
- adjust to your changing role and responsibility
- employ cost effective operation and maintenance methods
The success of long-term cost effective operation of a stormwater management facility depends on the 1) appropriate design, 2) an efficient inspection program undertaken during the construction phase and 3) the adoption of well organized operation and maintenance practices. This workshop describes all the above aspects of stormwater management by assisting the designer to produce a cost effective design, with low maintenance cost and long-term trouble free operation.
Similarly, the workshop will assist those involved in the operation and maintenance program to understand the design principles, the required performance of the facility and to ensure that the BMP facilities are operating at their maximum efficiency over it useful life.

- Aquatic habitat protection
- Erosion, meandering, morphology
Selection of Design Criteria
- Post and pre-development criteria
- Flood and flood plain
- Water quality
- Erosion control
- Major-minor system
- Water balance and recharge
- Effect of climate change

Questions and Answers and Feedback to Participants on Achievement of Learning Outcomes
Nav Sandhu, P.Eng., is a Senior Water Resources Engineer with over 18 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, 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, coupled with municipal, and development, and highway experience, makes him an excellent resource for a range of clients. He has also provided expert opinion and reports or legal proceedings related to drainage throughout BC.
