In the next few weeks I'm planning a trip to toronto where I'll hopefully explore a few drains. Because it's the winter though there are a few worries on my mind.
- I live outside Toronto need to know if there's too much snow melt or not to go draining.
If you're entering via the outfall, you'll know if there's going to be a problem or not. But I think your main concern will be rain on melt days, not the melt itself.
|- am also wondering if the ice and snow will cause any problems opening outflows to get into the drain itself.|
Sometimes, yes, although typically the outfall stays warmer. Watch yourself on surrounding surfaces. Swing gates don't typically have a point that can freeze. Also don't forget that some spots inside will still be slippery, and that if it gets really cold outside you can even see ice form internally in shallower storm sewers. Also manholes become unusable at cold temperatures, the rims ice.
