Why is stormwater management important at UBC?

UBC operates a separated sewer system, whereby the stormwater and sanitary systems and flows remain separate through distinct piping infrastructure.

Stormwater is water that originates during precipitation events and snow/ice melt. When stormwater is absorbed into the ground, it is filtered and ultimately replenishes aquifers. Stormwater runoff is water from excess rain or melting snow that “runs off” across the land instead of seeping into the ground. This runoff is not treated in any way and usually flows into the nearest stream, creek, river, lake or ocean.

Surface runoff at UBC could be a significant source of water pollution. It includes all flows discharged from the University’s land uses into the stormwater conveyance systems, and may carry a variety of materials that have potential negative impacts on water quality. It may include sediment, excess nutrients, metals and trace elements, organic contaminants, floatable materials, oxygen demanding materials, oil and grease, and harmful bacteria and viruses. Most of these materials also have a negative impact on the survival of fish, either through toxicity or degradation of habitat.

UBC Catchments

The UBC stormwater discharges either directly into the marine environment or enters small streams which flow into steep ravines in the Pacific Spirit Regional Park and eventually into the Musqueam Marsh, an area of estuarine marsh and mudflats on the North Arm of the Fraser River.

Refer to the UBC Drainage Map. There are four stormwater catchments, which drain surface water runoff from the UBC Vancouver Campus:

  • North catchment – drains the northern campus area, west of Wesbrook Mall & north of Agronomy. Flows are collected and conveyed to the spiral drain shaft (a large diameter vertical pipe) at Cecil Green Park House, which redirects stormwater directly into the ocean.
  • West catchment – includes Hawthorn Place, Totem Park Residence and UBC Botanical Garden.  Flows are collected and conveyed to the ravines at the Trail 7 outfall.
  • 16th Ave catchment – drains an area along 16th Ave, near SW Marine Drive.  Flows are collected and conveyed to the ravines west of the UBC Botanical Gardens.
  • South catchment – drains southern areas of campus including Thunderbird Park, Acadia Park, Hampton Place and all south campus. Flows are collected and conveyed through ditches along Marine Drive to a culvert that crosses Marine Drive and discharges to the Booming Ground Creek outfall.

What are the UBC stormwater pollution prevention guidelines?

Depositing or permitting the deposit of any substance which is likely to be rendered deleterious to aquatic habitat (e.g. fish, organisms, plants, etc) is prohibited.

Several UBC operations and activities may have a negative impact on our storm water if not managed properly. SRS Environmental Protection works with staff, faculty and students to ensure proper management practices are in place to prevent stormwater contamination and the potential impact on aquatic habitats. Follow UBC’s Stormwater Pollution Prevention Guidelines
