context_page_description: A catchwater device is a large-scale man-made device for catching surface runoff from hills and the sky from precipitation by channeling it to reservoirs for commercial and domestic use later. Freshwater is a scarce natural resource due to pollution, droughts, and overpopulation. Catchwater is a sustainable mechanism to increase freshwater in areas facing droughts or polluted waterways.
context_section_description: An earthship drain is water that is collected from impervious surfaces that are channeled into cisterns. A cistern is a well located underground. The water within these underground wells is heated by the sun. The water that is stored is used in domestic ways for washing dishes and bathing. Once water is used it is cycled and filtered in a module to be reused again
