#1: The strength and integrity of the outlet structure.
It’s important to discover cracked concrete and other visible signs of damage as soon as possible. All grates should be cleaned and checked for debris and sediment blockage. If the facility has a low flow orifice, it needs to be free and open. The low flow orifice lets the water drain slowly after rain so that the suspended particles have time to settle. If the outlet structure has a concrete box, nothing should be present that may impede the flow of water. Signs of erosion should be checked for above where the structure meets the pipe. This is often an indicator of a gap in the seal and the beginning of a sinkhole.
#2: Functionality of emergency spillways.
In the event of heavy rainfall over a short period, debris can quickly block the outlet structure before anyone has a chance to clear it. An emergency
