Dissecting the Average Shower and Its Impact on the Planet: An Invitation to Collaborate — Part Two: The Recirculating-Shower Design Elements

By Linda Pope

Abstract: Part Two of a two-article series describes water conservation through graywater use and rainwater harvesting. Sustainable methods of heating water for a recirculating shower, and potential methods for water filtration and purification are presented. Also addressed is the feasibility of sustainable showering alternatives. An opportunity for educators and students to collaborate in the development of an off-grid recirculating shower is provided as well.

Dissecting the Average Shower and Its Impact on the Planet: An Invitation to Collaborate — Part One: Human Water Usage and Global Impact

By Linda Pope

Abstract: Part One of a two-part article outlines a brief history of showering and questions current showering practices. Current global levels of water use and availability are discussed, plus water use in the United States, relative to Americans’ frequency of showering. The energy requirements for cities to provide clean water is outlined as well as the carbon dioxide emissions that are subsequently released during water delivery and wastewater disposal. In Part Two, water conservation through graywater use and rainwater harvesting is described, and sustainable methods of heating water are offered. Possible methods for water filtration and purification are presented. The feasibility of alternatives for a more sustainable shower is addressed. Both articles conclude with an invitation to students and instructors to collaborate with the author to construct a prototype of an off-grid recirculating shower.
