Syphonic systems are self-cleansing because of the high flow rates, thereby minimising maintenance costs
Downpipes are generally located inside buildings which provides visual enhancement in the majority of situations
Demands from architects and contractors on modern buildings can often make the installation of conventional rainwater drainage a difficult task.
Several factors have to be considered to make syphonic
rainwater system work effectively. Specially designed
roof outlets take into account rainfall intensity rate and to
design the pipework configuration to optimise
Rainwater removal from roofs has to be quick with a high level of safety. Occasional high rainfall rate over a short
time has to be considered with the design of an overflow system to cope with the high demand.
Rainwater can be easily routed to collection tanks for future recycling, e.g. irrigation, fire ponds, sanitation etc.
Syphonic outlets are designed to reduce the entry of air into the system and stops vortices forming that will draw more air into the system rapidly. Pipes are designed to run 100% full of water at high velocity from roof level to ground level, vastly increasing the capacity of the system when compared to traditional methods of roof drainage.
Acceleration of construction programme due to reduced installation period.
Software packages save time and provide: Isometic drawings, Hydraulic calculations, Material lists including fixing components. All documents are available in hard copy or can be emailed anywhere in the world.
