Gravity Sewer Storm Drain Design: 

Grated (In Sump) - Low Flow
  • Calculate the capacity of flow volume (Q) of a grated inlet in a sump with depth of water flow less than or equal to 0.4 feet.
Grated (In Sump) - High Flow
  • Calculate the capacity of flow volume (Q) of a grated inlet in a sump with depth of water flow greater than 1.4 feet deep.
Curb - Low Flow
  • Calculate the capacity of flow volume (Q) of a non-depressed curb inlet with depth of water flow less than or equal to 0.4 feet.
Curb (In Sump) - Low Flow
  • Calculate the capacity of flow volume (Q) of a curb inlet in a sump with depth of water flow less than or equal to 0.4 feet.
Curb - High Flow
  • Calculate the capacity of flow volume (Q) of a curb inlet in a sump or not, with depth of water flow greater than 1.4 feet deep.
Slotted (In Sump) - Low Flow
  • sump slotted inlet for a flow volume (Q) with depth of water flow less than 0.18 feet.
Slotted (In Sump) - High Flow
  • Calculate the required length of sump slotted inlet for a flow volume (Q) with depth of water flow greater than 0.18 feet.
