A well-thought-out dewatering plan is important to the success of any jobsite. Dewatering pumps often are necessary to remove groundwater and rainwater in order to perform work safely, but it is crucial to abide by the applicable laws and regulations and consider how selected dewatering methods will affect the environment. Each site has its own dewatering challenges, and it is important to consider all options, especially regarding discharge of water on a jobsite.

Another example is the rice terraces of the Philippines, which are still in existence today. More sophisticated rainwater systems have been uncovered by archaeologists in Crete, Istanbul and throughout the Mediterranean region.
