Catch basins are typically used tocollect surface runoff from developed parcels of land, while manhole structuresare typically used to change pipe size, pipe material, direction, gradeand elevation. For commercial developments, PVC or HDPE catch basins arepreferred. Concrete does not bond to HDPE pipe.Regardless of the type of structure or type of pipe being connected to,there are basic engineering areas of concern: differential settlement betweenthe pipe and the structure, and the connection between the pipeand structure. Addressing these two concerns with proper installationtechniques helps ensure that the system will meet long term expectations.Proper installation techniques to address these concerns are addressed inthe next few paragraphs.3.4.1 Transitions to Manholes, Catch Basins andEAGLE CORR PE INSTALLATION GUIDE29
