Stormwater Management

Why SWM plan?

– Among the civil engineering disciplines in construction projects, the SWM is one of the most important ones; especially in the Metro Vancouver with 1000-3000 mm annual rainfall.

– Nobody likes to have a building with risk of basement flooding, leakage, foundation scouring and settlement, un-functional  sump pump and un-necessary pumping electric bill during the building life cycle.

– The new developments increase the quantity and affect the quality of the water, and those both are the biggest threat to our infrastructure, creeks, and more importantly to the wild life habitats in the creeks and ocean.

– New architectural plans cause new pattern of run-off and ground water movement, so we need to consider SWM carefully.

– As per the global climate change, the rainfall patterns are changing, and we have to see this in our plans for future.


– Nobody likes to underestimate the safety, functionality and quality of any development plan because of negligence and ignorance for miscalculation or lack of knowledge of the hired professional. Having dozens of successful SWM plans in the Metro Vancouver, ITMBC’s goal is set to make sure that all plans and designs are being technically prepared and comply with the latest standards and codes. Beyond the technical criteria of the design, we do an extensive risk assessment of stormwater management in our projects which has many years of experience and knowledge behind it.

– Considering this job as a challenging task, like a large watershed hydrological studies, many uncertainties and lack of information are involved in the SWM design for residential and commercial buildings. Our professionals at ITMBC use the latest, most advanced and up to date methodologies to mitigate the risk of flooding and water damage during the building life cycle.

– At the ITMBC, we have understanding about the Hydrology, Groundwater, Hydraulics, Sanitary and Stromwater Infrastructures, Habitat Related River Engineering, Pump Station and Automation, Material Knowledge about the water and sewage supplies which we normally use in our SWM plans.

– Upon your call, we normally visit your site and meet with you to understand the needs and to define the scope of work. Then we present our proposal for design of SWM plan for your project. This is a no obligation step and we   enthusiastically follow  this manner as a part of our daily job. We deliver this service and assessment to the property owners, builders and developers in any stage of development from conceptual plan to permitting and during and post construction.

“This job is a science and needs to be done very carefully”
