Stormwater Open Curb Inlet Survey Guide
Fabco’s Stormwater Open Curb Inlet Survey Guide is a step by step set of instructions to help you work through the stormwater grate inlet survey.
Fabco Industries Water Quality Inserts (WQIs) are manufactured to properly fit inlets by using specific information compiled in a survey of the “as-built” inlet. Below are a set of guides to help with any issues you may have when completing the open curb inlet survey.
