Why should we care about managing our stormwater?
Prince George's stormwater drainage system collects runoff water from rainstorms, snow melt, and residential and commercial water usage. The water - collectively called "stormwater" - travels through a network of pipes, culverts, and ditches, eventually making its way to a natural water course or retention pond.
Managing this stormwater is essential to prevent:
- Sedimentation/degradation of water quality
- Negative impact on aquatic life
Urban development, in particular, impacts peak flows by increasing the number of areas that can't naturally absorb stormwater (unlike creeks and rivers). Instead, stormwater from building roof drains and asphalt parking lots flows into catch basins and from there enters the storm sewer system or a recharge chamber.
Our stormwater story
Our stormwater system at a glance
Prince George's stormwater system consists of a massive network of pipes, drains, and other infrastructure that works together to divert water to its intended destinations. We have:
- 385 kilometres of below-ground piping.
- 690 kilometres of open ditch or drainage channels.
- 962+ culverts
- 5,789 catch basins
- 6 stormwater pumping stations
- 4,087 manholes
- 25 storage basins (detention and retention ponds).
- 224 inlet structures.
- 73 subsurface infiltration facilities.
- 293 outlets to receive water.
Spring melt and flooding
Spring is a time for renewal, but it also means renewed risks of flooding as snow melts and our stormwater system works to avoid being overwhelmed by the sheer volume of water entering the network.
Here are some things you can do to help us and, in a worst-case scenario, mitigate flooding on your property or in your neighbourhood.
The Integrated Stormwater Management Plan
Stormwater management is becoming a higher priority in Prince George because of more intense storms, aging infrastructure, and urban development.
As our community grows, there is potential for a drastic decrease in natural areas and an increase in "hard" impervious surfaces, such as roads and buildings, that can't naturally absorb stormwater. Failing to manage stormwater properly can lead to issues such as erosion, contaminants in our creeks and rivers, and flooding on roads and properties.
