NC-2009 SSc6.1:Stormwater Design—Quantity Control

Drainage Pipe Capacity

Can we count the capacity of underground drainage pipes as the retention capacity? The pipe capacity will then add to the stormwater retention capacity. This method will significantly reduce the need for a large retention tank. Does anyone try this method in a simulation program and what about the response from the reviewer? thanks
