The Benefits

Siphonic Roof Drainage Vs. Conventional Roof Drainage

Siphonic systems are gaining traction in the roof drainage market as a substitute to conventional drainage methods. Designing a system that runs full bore and with out any fall has obvious benefits over the traditional conventional method.

Some of the benefits of a siphonic system over a conventional system are listed below.

• Time and cost reduction
  Significant savings of time and money in overall construction and facility operation
• Less need for groundwork
  The horizontal collecting pipework runs just below the roof rather than below ground so there is limited need for site trenching, bedding and backfilling
• Fewer roof outlets required
  Typically there is one horizontal siphonic downpipe to every 8 to 10 conventional downpipes
• Single vertical downpipe and smaller diameter pipework
  Several outlets are connected by horizontal pipework to a single vertical downpipe
• Greater asthetic appeal and design innovation
  Allows architectural and design solutions that would not be available with conventional systems
• Flexibility and simplicity in routing of pipework
  No fall required on horizontal pipes
• Self cleansing
  Due to far higher flow velocities in the pipework
• Rainwater Harvesting
  Rainwater can be easily routed for storage and reuse
