The unique features of siphonic drainage make it ideal for commercial buildings, especially those covering a large area such as warehouses, shopping centres or factories. The smaller number of easily accommodated downpipes makes it particularly suitable for cutting edge architecture where conventional drainage would impair the aesthetics of the design.
The benefits of siphonic drainage include:

• Reduced costs due to fewer, narrower pipes and limited discharge points
• Less complex underground drainage requirements
• Horizontal pipes laid internally make positioning of other services easier
• Greater architectural freedom
• Smaller and fewer pipes lead to easier installation and maintenance
• Self-cleaning of pipes through higher water velocity
