What is required for the discharge of rainwater downspouts in terms of drainage?

Discharging rainwater downspouts into an approved drainage system is essential for several reasons. Firstly, an approved drainage system is designed to effectively manage stormwater runoff, reducing the risk of flooding and erosion, and directing water to appropriate treatment or discharge locations. This ensures that the rainwater is handled in a manner that complies with environmental regulations and community standards.

Furthermore, discharging directly onto the ground may cause localized flooding or erosion, while using barrels for water collection might not serve the purpose of drainage, especially during heavy rainfall. Sump pits, on the other hand, are typically used for collecting and pumping away groundwater rather than managing roof runoff specifically.

By directing downspouts to an approved drainage system, compliance with building codes and guidance set forth in the National Plumbing Code can be maintained, safeguarding both the property and surrounding areas.
