Rainwater Collection is a means for collecting, storing, and using rainwater to irrigate landscapes and provide an alternative water source for household use (after filtration). This natural and traditional practice reduces our need for treated municipal water and enhances the quality of the natural systems that utilize it by providing a pure source of local and free water. Plenitud demonstrates multiple methods for collecting rainwater off of hard surfaces such as our classroom roof as well as techniques for harvesting rainwater through earthworks.
Active Rainwater Collection
Active Systems-Design Principle & Components: collection surface, gutter, downspout, first flush, cistern, outlet plumbing
Cisterns and Tanks: different materials, placement, foundations, algae growth
Using the water: Outlet plumbing, filtration, pump versus gravity feed, irrigation systems
Passive Rainwater Collection
Passive Collection is in the soil and in the plants and treesand how it fits within Permaculture design
Methods: through earthworks, mulches, and plants & Precautions and key design principles for safe and effective earthworks
Start small with a shovel and micro-earthworks to plant the rain!
Earthworks: Terraces; Swales, “berm n’ basin”; Infiltration basins; Ponds and dams; Check dams with rocks, wood, or brush
Using mulches and appropriate plants to use the water you harvest in earthworks
Integrating your earthworks and planting patterns into the larger garden or farm system
