Adequate difference in height of at least four metres between the roof and the buried drains.
Several of these drains tie into a horizontal collector that is routed to a convenient point where it transitions into a vertical downpipe this downpipe once it reaches the ground is piped to a.
Conventional gravity fed roof drainage systems rely on gravity and water s ability to spread out and flow to the lowest point channeling from the roof down through the gutter outlets and downpipes to the ground below.

Drainage of large roof surfaces requiring a minimum outflow capacity of 1 0 l s.
Siphonic drains are like other roof drains in that they are connected from the roof to the storm drain by a series of leaders or downspouts.
This air baffle is engineered and tested to prevent air from entering the piping system at peak flows.
We look forward to working with the professional team at mullen corporation.
