Roofing rainwater drainage and collection system has dual
function of rainwater drainage. Following the flow pattern in
the roof rainwater drain line, the system includes three
systems namely gravity flow, semi-pressure flow and siphon
flow. Rainwater in gravity flow system is not fully filled;
rainwater in semi-pressure flow system is demonstrated via
mixture of air water in pipeline; rainwater in siphon flow
system is fully-filled on way. Different system should apply
professional roof drain.

During raindrop, roofing runoff rainwater is converged in the
gutter that enters drain pipe through rainwater of various
forms. By installing rainwater sundry sewage inception, part
flow arrangement or split-flow devices in the rainwater
vertical drainage pipe and blow-off pipe so that it discharges
rainwater to rainwater pipe network at the outset of rainfall
and when rainfall runoff rainfall reaches the pre-set data,
spilt-flow device would automatically turn off the split-flow
pipe and the system enters rainwater collection stage with
rainwater collected entering water storage pond.
