“Water Resources Engineering (WRE) connects engineering hydrology and hydraulics with global, economic, environmental, and societal issues. Our student Katarina Bagri makes this connection here…”

The news article, “What is Earthship Malaysia?” published by Clean Malaysia on March 20th 2016 reports on the new Earthship that will be built in Malaysia. After describing what an Earthship is, the article then continues to go in depth on the grey water system that Earthship utilizes in their designs. The grey water system they lay out in detail begins with harvesting rainwater that then goes through several filters and transported to outlets through the house for external use only (washing hands, clothes, & shower). Once that water is used, it’s carried to planters where it serves as a water source for the plants as well as gets filtered through a series of soil and bacteria filters. After this step, it’s officially called grey water and is pumped into the toilets of the house. And then once it’s used in the toilets, it becomes grey water and it sent to the on site septic tank. This type of grey water system conserves water, a vital and depleting resource, as well as decreases the money needed to be spent on water for a home. This system not only makes individuals more responsible for their part in the water cycle but also entails them to think about water on a more personal level than they would in a regular home water plumbing system. Having worked with Earthship Biotecture and having been an apprentice to a grey water system plumber, on top of taking hydrology & hydraulics, I can confidently conclude that the article was very accurate in their WRE facts. Since the article was reporting on more of what an earthship is rather than what a greywater system is, there wasn’t really any important information missing in regards to WRE.

On a WRE broader context, this article deals with both global and economic as well as environmental areas of hydrology and hydraulics. Water is a global resource that is very quickly depleting so that it tied in. Grey water systems are a much cheaper route to take when it comes to obtaining water in a home, so that’s how it encompasses the economics side of it. And it’s clearly environmentally aware article because recycling and reusing your water is one of the most environmentally friendly things you can do with water. In the scientific journal titled, “Overview of Greywater Use: The Potential of Greywater Systems to Aid Sustainable Water Management” by the Pacific institute the various greywater technologies along with policies and regulations are discussed in depth. The article does a great job of corroborating with the WRE issues impacted previously examined from the original article.
