Rainwater Harvesting Roof Surfaces.
|
Information modified from Jesse Savou, ARCSA https://www.bluebarrelsystems.com/blog/roofing-materials-for-rainwater-harvesting/

|
Roof Surfaces Recommended for Potable Use
|
Standing Seam Metal Interlocking panels run vertically from the roof’s ridge to the eave with seams that are raised above the roof’s flat surface. Water runs off without seeping between panels.
|
EPDM Ethylene propylene diene monomer A rubber-like compound used in roofs in the U.S. since the 1960s. One of the most common types of low-slope roofing materials. This is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional built-up roofs.
|
Slate or Tile Slate is a good surface to harvest rain from as long as it is kept clean and does not deteriorate. These materials do not include asbestos tiles, which have been mainly used as siding in the past but could potentially be found on some roof surfaces.
|
Composition tiles Particles like those coming from composition shingles can be easily filtered out.
|
Corrugated metal Corrugated metal also makes an efficient collection surface, however, most corrugated material is galvanized, which will leach some zinc into the rainwater. Many people collect from galvanized roofs with no problem, but this is something to be aware of. Collect a sample of rainwater and use a home test kit or send it to a lab to make sure zinc levels are below allowable limits for drinking water.
|
Roof Surfaces Not Recommended
|
Asphalt Crumbling asphalt roofing material debris can be separated during filtration, but this type of shingle can also leach petroleum products into the water. These contaminants can also be removed from the captured rainwater, but it is preferable to keep them from entering a system in the first place.
|
Unprotected metal Can contribute to heavy metal levels that are unacceptable. Some modern metal roofs may be exempt especially if they include protective coatings.
|
Tar and gravel This type of roof can overwhelm filtration necessary for potable rain harvest.
|
Wood shingles Wooden shingles are porous and can be a fertile medium for the growth of mold and fungi. They are also treated with chemicals that are intended to protect the wood but are neither intended nor acceptable for human consumption.

short-cycle animal species, such as poultry, rabbits, guinea pigs, as well as mid-sized livestock such as pigs, sheep and goats, although cattle and even buffalo are also raised for meat or dairy production. Urban aquaculture systems can be associated with a multitude of different production locations, species used, environment, and production intensity in rivers, ponds, lakes or canals.

Institutional food growing

--------------------------------------------------- Unstructured Sub-Title End
|
covers a wide variety of gardens and farms around the world. It includes projects on institutional land belonging to schools, universities, religious bodies, prisons, municipalities and other governments, public authorities, hospitals and clinics, prisons, among others. The projects include gardens for own consumption, therapy, leisure, development of knowledge and skills, and job creation, as well as commercial farms for profit and economic development. A few institutional projects are set up and managed by the institutions themselves; in other cases, institutions provide land and other support (from water to training) to projects that have been established by diverse groups, while in other instances, institutions simply lease the land or offer it for free.
|
To highlight one subset of institutional food growing, educational gardening covers a particularly wide range of forms. School and university gardens offer an important opportunity for ecological and nutritional education. In these non-traditional learning environments, youth become familiar with healthy and nutritious food, especially fruits and vegetables. Programmes in these gardens teach skills and establish a lifetime hobby that provides exercise, mental stimulation and social interaction. Some schools and universities have teaching farms that incorporate marketing skills and advanced knowledge. Beyond schools and campuses, educational urban agriculture includes extension services for farmers, rehabilitation for troubled youth and former convicts, and intergenerational learning.
