Water Cisterns: Tree People & The Center for Community Forestry

Tree People Cisterns: http://www.treepeople.org/cistern

The coolest interactive demonstration I've seen in awhile from a nonprofit organization allows you to model out your own cistern project and look at rainfall collection as it can be used throughout the year for agriculture, fire safety & other essential needs.

This allows for easy water collection across a whole village area, reducing the need to hike long distances or drill for water in desert regions that receive some rainfall during a rainy season.

Cisterns are fabulous inventions that have been around for centuries -- in Los Angeles the Tree People put cisterns beneath schoolyards so that they can keep grass year-round without watering from an outside source. Cisterns in other regions provide essential drinking water in places where no other options exist, such as island nations where all ground water is salt. Rain catch systems can be a beautiful sculptural addition to areas where the flow of water is essential for aeration. In other regions consider closed systems to reduce environmental contamination: for example regions such as Haiti where sanitation issues are extreme during rebuilding and cleanup.

How big is the cistern?

The TreePeople cistern is a circular tank, 70 feet in diameter and 8 feet deep. It is made of concrete and has a steel-reinforced roof held up by concrete pillars. This enables it to withstand the weight of fire trucks in times of emergency – when the water in the cistern can be used by our local fire department.

I know this post is about water but the sustainability model for Los Angeles also on the website is an encouraging approach to solving the issues of a big city.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle.

In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
