Surface Water Management (SWM)
Surface Water Management (SWM) provides water quality protection for the community by implementing programs, which reduce pollution in our rivers, streams and wetlands caused by urban stormwater runoff.
Stormwater runoff is the most significant source of water pollution in our state. It washes pollutants into storm drains and drainage ditches, carrying silt, oil, chemicals, trash and pesticides to the nearest creek, stream or wetland. The polluted runoff can harm fish, aquatic life, and threaten our drinking water.
Through watershed protection and planning, Water Environment Services (WES) is taking a long-term approach to protecting the health of our water resources.
What does the SWM program do?
- Maintains stormwater facilities
- Responds to customer service enquiries
- Monitors water quality
- Requires buffer zones between new development and wetland/creek areas
- Plans and designs regional water quality and flood reduction projects
- Provides long-term watershed planning
- Provides public outreach and partnerships for pollution prevention
Why do I pay a SWM fee?
Each resident of the community contributes to the cost of the program because we use the buildings, streets, parking lots and sidewalks that add to the need for a surface water management program. Developers also pay for the cost of building, the drainage systems and water quality facilities serving their development.
