Q: How far can a siphonic drainage system run horizontally?

Q: Does siphonicroof drainage improve the green star rating of my building?

 

 

A: This depends on the flowrate and the height of the building but as a rule of thumb; the horizontal pipe run can be 10 times the downpipe height (e.g. with a 8m height from the gutter to ground, the siphonic drainage system can drain 80m horizontally without the need for gradient). Even at ground level, the siphonic drainage system can run flat in normal (siphonic) pipe size to a drainage point (swale, soakwell or culvert) away from the building.
