Understanding our Urban Stormwater Drainage System

Stormwater Drainage System Function
💧 Streets are designed to be part of the stormwater drainage system, channeling rainwater from properties into gutters, drains, and underground networks.
🌊 During severe storms, water flows to the nearest outlet, like a drainage basin, creek, or river.
⏱️ Clearing time for flooded streets can take several hours, depending on the storm's severity.

Flood Risks and Causes
⚠️ Flash flooding in streets occurs when drainage basins or river levels are high, meaning the stormwater system outlet is overwhelmed.
🚫 High water levels above the outlet point cause a backup, as there is nowhere for the stormwater to go.

Community Responsibility and Safety
🧹 Keep the system clean by not washing debris like lawn clippings or leaves into drains; use the green bin instead to prevent blockages.
🚗 Do not drive through flooded areas, as this pushes water back into homes and businesses.
📞 If you see stormwater backing up from drains, do not attempt to stop it; call the customer service help desk for assistance.

Key Points & Insights
➡️ The primary goal of community care is protecting homes and businesses by ensuring the stormwater system remains clean and clear.
➡️ Green bins are the correct disposal method for yard debris that could otherwise cause dangerous drainage blockages.
