The following is a typical construction sequence to properly install an infiltration practice:
#The area should be fully protected by silt fence or construction fencing to prevent compaction by construction traffic and equipment.
*The area should be fully protected by silt fence or construction fencing to prevent compaction by construction traffic and equipment.
#Installation may only begin after entire contributing drainage area has been either stabilized or flows have been safely routed around the area. The designer should check the boundaries of the contributing drainage area to ensure it conforms to original design.

#The pretreatment part of the design should be excavated first and sealed until full construction is completed.

#Excavators or backhoes '''working adjacent to the proposed infiltration area''' should excavate to the appropriate design depth.

#The soil in the bottom of the excavation should be ripped to promote greater infiltration.
