Siphonic Roof Drainage System

ROOF DRAINAGE SIPHONIC

Siphonic system with fewer drains and a small-diameter horizontal pipework system underneath the ceiling. More water is transported through the pipework due to faster flow and a filled pipework system, reducing if not completely removing below-ground drainage.
