“Greywater is a fabulous, though often underused, household resource that should be used wherever possible. Here’s a home made 3 bathtub greywater system that’s simple but effective.

If you live in an area where water is precious at certain times of year (and when is it not?) then catching, storing and using every drop you can to create a more liveable home and surrounds is an excellent idea.

At Melliodora in Victoria, the studio cottage does its best to do just that, by catching, filtering and re-assigning the greywater to useful purposes in the garden.

While this design will not suit everyone, it will suit some, and it’s a simple, cheap and effective way to deal with, process and make the most of a small household’s greywater…”

Explore the world’s new coastlines if sea level rises 216 feet. The maps here show the world as it is now, with only one difference: All the ice on land has melted and drained into the sea, raising it 216 feet and creating new shorelines for our continents and inland seas.  There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all. If we continue adding carbon to the atmosphere, we’ll very likely create an ice-free planet, with an average temperature of perhaps 80 degrees Fahrenheit instead of the current 58.

A low-tech water filter system made from a branch of a tree can filter up to four liters of water per day, removing up to 99% of E. coli bacteria and producing fresh, uncontaminated, drinking water.

A team at MIT used a small piece of sapwood, which contains xylem tissue that transports sap inside the tree, to build an effective water filter that could make a big difference in places where contaminated water is the norm. By using this type of filter, rural communities may be able to solve some of their water issues in a low-cost and efficient manner.

“Today’s filtration membranes have nanoscale pores that are not something you can manufacture in a garage very easily. The idea here is that we don’t need to fabricate a membrane, because it’s easily available. You can just take a piece of wood and make a filter out of it.” – Rohit Karnik, associate professor of mechanical engineering at MIT…

Types of Water Bodies

Lakescientist.com writes…

…River systems make up about 0.0001% of the Earth’s water. While this may not seem like much, rivers drain more than 75% of the Earth’s surface. Rain and other types of precipitation move water overland, through terrestrial ecosystems and into river systems. The resulting runoff brings inputs of sediments, nutrients, and materials into the river, causing running waters to be highly influenced by their surrounding landscapes (see land use and runoff). The flow of river systems carries the sediments, nutrients, and other materials through the landscape and into other systems, providing vital linkages between the land, lakes, wetlands and oceans. It is because of this that rivers are often referred to as the environment’s circulatory system…”

As part of a permaculture design we are creating for Center for Sustainable Community (CSC – our local non-profit) we developed a few educational tools to help us explain several concepts we wished to convey to them.  One of these is the idea of planting in linear-food forests all along the downhill side of several hugelkultured swales.  We thought you might like to see these explanations as well.  

While the tress and shrubs are in the early stages of growing (small) we will use the open space to grow some of our annual vegetables. We will also plant some nitrogen fixing ground covers and dynamic accumulators to help build the soil.
