The 2320 South Storm Drain Project involved the installation of 320 feet of 24" x 38" Elliptical Reinforced Concrete Pipe and a Cleanout Box.

The purpose of the project was to divert storm water that drained into a small drainage ditch to another ditch several parcels of land could be improved and improved.

The phases of the project included an intial survey phase, the design phase, and the construction phase.

The intial survey phase involved a GPS survey to locate all utilities and create a general topo model of the area. Further surveying using a transit was used to get flow line elvations of the existing storm drain system.

The design was performed in MicrostationTM using InRoads(R) software. The pipe sizing was chosen based on flow capacity using Manning's Equation. Because the terrain was relatively flat a large pipe was needed for adequate flow capacity. In addition, the existing pipes were at shallow depths, so elliptical pipe was used to provide adequate spacing for the road base.

The construction phase was inspected using surveying and visual inspection. Compaction testing on the road base was performed with Nuclear Density Gage testng. To verify the pipe was clean of debris material and proper connections were made between pipe segments, a robotic camera was used in the pipe to look at the interior of the pipe.
