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



A: Yes, all pipes and fittings are made of environmentally friendly HDPE (high density polyethylene) and is 100% free of PVC. HDPE does not break downwith timeand is 100% recyclable. Furthermore, siphonic drainage can "transport" the rainwater over longer distances, and hence makes it more practical to collect a larger area of roof to a rainwater storage tank compared to a conventional drainage system.
