	"[[Construction]] of many conventional water projects such as dams, dikes, [[canals]], [[siphons]], and pumping plants requires some degree of excavation, which often extends below the local water table.

			"Design of WR&C systems should rely as much on experience as on the theory and calculations. Each site is unique, and no two systems will be exactly alike. Additionally, there is no one correct design, although some designs may be more applicable than others to specific site conditions. A well-suited design may include multiple features employing different technologies and configurations to achieve the desired goals."<ref name="DS13-21"/>
