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 frost penetration depth, or cisterns integrated within buildings. | Freezing temperatures can cause problems with exposed collection pipes and portions of cisterns and pipes located above the foundation frost penetration depth.
