What is the maximum flow rate for the Z882 Trench Drain System?

  • ​The maximum flow rate of each numbered section of open ended channel can be found on the spec sheet for the product listed above.   The flow rate increases as the trench gets deeper.  However, if you were to put an end outlet or bottom outlet on this channel to direct the flow to a specific sized pipe, the flow rates will decrease and be dictated by the flow capacity of this pipe.  If you provide Zurn with the specific pipe size and depth of trench you are interested in, we can estimate the flow through that outlet.
