SWMM - LID Controls - Rooftop Disconnection

Relhado Disconnect - causes downspouts to discharge into landscaped areas and permeable lawns instead of directly into storm drains. It can also model roofs with directly connected drains that overflow into permeable areas.

Schematically:

• Rooftop Disconnection
  • Flow Capacity - Maximum Flow RateUse zero if not applicable
• Surface
  • Gutter Height - Storage Height
  • Slope - Surface slope
  • Surface Roughness - Roughness
