[[Weirs]] are generally less prone to clogging from ice than [[orifices]] under all flow conditions, proprietary low flow devices are also available which are designed to mitigate clogging from ice or other solid debris.

===Plowing===
Rubber plow blades are increasingly available and required in many jurisdictions. Their use reduces damage to all kinds of pavement surfaces and they are particularly recommended for application on LID systems including permeable pavements and curb cut inlets of bioretention, bioswales, swales and stormwater tree trenches.
===[[Rainwater harvesting]]===
===[[Rainwater harvesting]]===
Freezing temperatures can cause problems with exposed collection pipes and portions of cisterns and pipes located above the foundation frost penetration depth. For standard drawings see [https://www.library.mto.gov.on.ca/SydneyPLUS/TechPubs/Portal/tp/opsViews.aspx Ontario Ministry of Transportation] OPSD 3090.100 for northern Ontario, and OPSD 3090.101 for southern Ontario. Rainwater harvesting systems designed for year-round operation in cold climates like those in Ontario are typically limited to underground cisterns and outlet pipes located below the foundation frost penetration depth, or cisterns integrated with buildings.
