San Isidro Permaculture can create catchment systems to suit your site and to fit any budget.
Current drainage systems and designs try to quickly direct water off your site to avoid flooding problems. Our approach uses your land to redirect, absorb, and hold rainfall, thereby reducing flooding problems and irrigation needs. Rainwater from a roof can be filtered and stored in rain barrels, underground tanks (cisterns), or aboveground tanks, and then used for irrigation or other outdoor uses. (Also see
ferrocement
tanks.) Stored rainwater can be easily treated and become a potable water source.
Impermeable surfaces — roads, sidewalks, patios, etc. can be redesigned to infiltrate water or direct runoff to vegetation areas.
These catchment techniques can decrease your irrigation water consumption while recharging the groundwater table. Vegetation responds more positively to rainwater than treated (city) water due to its low dissolved mineral content and because it has no residual chlorine.
