Siphonic Roof Drainage

A Siphonic Roof Drain System is about half the size of a conventional system. The advantages include a material cost savings, a labor cost savings, concealed pipes with reduced or even eliminated wall furring and a savings of square footage. These systems are also installed with level horizontal pipes (no slope). This allows for greater ceiling heights, lower overall building heights, reduced coordination conflicts, minimized pipe bracing  and additional labor cost savings. The system has no moving parts, uses virtually any pipe material and requires only a specialized drain that incorporates a baffle over the drain body. Overall, the system provides a reduced water depth on the roof and higher self-scouring velocities.

  • Generating and managing building data during its life cycle.
  • Using three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction.
  • Encompassing building geometry, spatial relationships, geographic information, and quantities and properties of building components.
