The primary function of bibliographic citations is to assist the reader in finding the sources used in the writing of a work. To these basic citations, the annotated bibliography adds descriptive and evaluative comments (i.e., an annotation), assessing the nature and value of the cited works. The addition of commentary provides the future reader or researcher essential critical information and a foundation for further research.
French drain. A French drain or weeping tile (also blind drain, rubble drain, rock drain, drain tile, perimeter drain, land drain, French ditch, sub-surface drain, sub-soil drain or agricultural drain) is a trench filled with gravel or rock or containing a perforated pipe that redirects surface water and groundwater away from an area.
The drain itself is an NDS 12-inch catch basin. I strongly recommend this over a drain grate unless your french drain is being fed by a downspout. By connecting your pipe to the catch basin, you're allowing water to flow into your drain without the silt or any other muck that might enter the grate.
