Rainwater Harvesting Example Systems
How Much Can I Harvest?
Did you know that your home is a potential powerhouse of rainwater catchment? For example, a home of 1,000 square feet can capture over 10,000 gallons of rain a year in an area of moderate rainfalls. This free water can be used to irrigate your garden and lawn, refill your toilets, wash your laundry and many other uses. Use this FREE Site Analyzer tool report tol help you determine how much rainwater your home and lot can potentially catch. Then you can take the next step toward building your own rainwater harvesting system.
Exciting demonstration site at Zilker Park in Downtown Austin, in the heart of downtown Austin, is set to become the prime Rainwater Harvesting demonstration. The recently completed system is fully visable and signed for public viewing and is meant to educate visitors in the forgotten benefits of rainwater. >> more
Starting Small and Grow
Most rainwater harvesting systems start small and grow with us. Many have been with us for years, starting with rain barrels then going on to bigger tanks or more sophisiticated systems over time.
Amy has grown her tanks in gallonage and overall numbers over the years. Most recently linking rainbarrels together and installing water measuring devices to ensure she does not over water her fruit trees.
Jody - Homemade Water
Have you ever dreamed about living off the grid and enjoying a totally self-sufficient lifestyle in a house you helped build? Jody Drew is living her dream. Years of dreaming and a ton of hard work came to reality in 2003. She harvests both rainwater and solar energy to live simply and more sustainably.>> more
Action Learning at Florida House: A Rainwater Harvesting Case Study
The Florida House Learning Center is a demonstration home and yard featuring an environmentally-friendly building, rainwater harvesting, and sustainable landscaping materials and methods. >> more
The Emerald Home
Completed in the Santa Fe area in the Fall of 2009 which included both active and passive rainwater catchment. It is a large awarding win green home built to the highest LEED standards and incorporates a state of the art building envelope, the most efficient windows and skylights on the market, geothermal heating, massive photo-voltaic arrays, low-water use appliances, new trees to provide passive summer cooling and a state-of-the-art water system. >> more
Duke Installs Rainwater Harvesting System
The LSRC (Levine Science Research Center) at Duke University has started up and commissioned a highly efficient rainwater harvesting system designed to flush toilets and urinals in the new facility. Rainwater is being collected from the roof of the facility pre-filtered by the WISY WFF 300 Rainwater Pre-filter before it is stored in a 12,000 gallon below ground storage tank.
Active Water Management
There are many ways to save water — conservation, passive rainwater catchment, onsite recycling (i.e., greywater) and active rainwater catchment. All of these methods require that you actively manage your water use, as opposed to just paying your bill each month and not thinking about how much water you use. >> more.
Bringing Green Home
Converting a shed to a home office in Santa Fe, N.M., took time, research and planning, but was worth the effort. By investigating products and working closely with the contractor, the 700-square-foot (65-m2) home office now is in business.
Tanks Can Be Beautiful
Because temperature swings are common in New Mexico, a basement below the shed helps regulate temperatures year round. Using the Earth’s constant temperature of around 55 F (13 C) and moving air from the warm parts of the shed to the cool sections in the winter and vice versa in the summer, the need for an HVAC unit was avoided. The basement walls are concrete block and covered with 1 inch (25 mm) of insulation board for an estimated R-value of 14 to 16. >> more.
To the delight of the green building community and many other Washingtonians throughout the state, the Department of Ecology issued a policy statement issued on October 12th clarifying that water rights are not required for either the use of or the on-site storage of rainwater collected by a rooftop system or a guzzler (Guzzlers are devices used to catch and store rainwater and dew to provide wildlife or livestock with drinking water.) >> more
A Simple Rainwater Harvesting Design
Australia mandates it. In Tucson’s 100-plus degree summer days, one well-known harvester has created a natural cooling and humidity system using it. Earthships and off-the-grid builders need it to survive. What is it? It is the next renewable revolution: rainwater harvesting. If you ask old-timers and the Native Americans here in New Mexico, they’ll tell you it is nothing new but merely coming to forefront as we take greater care to use our local resources in economical, sustainable ways. >> more
The Willow School: Teaching Sustainability
first thing that you notice at The
Willow School is the closeness of nature to each classroom.
Each room has its own door so children can move outside at a moment's
notice, and the ample windows draw the outside into the room. Preserving
the natural beauty of the area, the grounds design features include
many outdoor learning spaces and constructed wetlands for the
filtration of wastewater. >> more
