In a natural areas, rainfall or melted snow soaks into the soil, is absorbed by trees and plants, evaporates into the air, or flows into streams, lakes, rivers, and wetlands.
In cities, rainfall and melted snow
travel much more quickly over roofs, driveways, and roads.
Water runs off these surfaces, collects pollutants like dirt,
oil, fertilizer, grass-clippings, pet waste, litter etc. and
carries them too our rivers and waterways.
After storms, heavy rains or snow
melts, water levels can rise and cause flooding.
Stormwater management is an important part
of Guelph’s plan to withstand and recover from more frequent and severe storms
caused by climate change.
Help keep storm drains clear
Keeping storm drains and catch basins clear
of leaves, dirt, litter and ice helps reduce the risk of flooding during heavy
rain and storms.
Storm drains and catch basins let rain and
melted snow flow into our storm sewer system which drains into the nearest
stormwater pond, creek, river or lake.
Stormwater runoff is not treated before
flowing into local waterways – only rain should go down the storm drain.
Stormwater management ponds may look like
natural areas, but they’re actually an important part of the City’s
Stormwater management ponds collect melted
snow or water runoff from storm sewers, and slowly release it into our
Please don’t add or remove plants near
stormwater ponds. Plants and long grass help ponds function properly. We remove
debris and invasive plants regularly, without using pesticides. We also maintain
gates, locks, valves, etc. and perform repairs and bank stabilization, when
