branched drain systems rely on gravity to distribute water through a yard. greywater is collected at one or more fixtures (showers, baths, and sinks) and re-routed through a diverter valve in the crawl-space or basement. in the yard greywater flow is subdivided into progressively smaller branches, irrigating up to 8 mulch basins. this type of system is simple, reliable, and almost entirely maintenance-free. it's slightly harder to modify than some other systems if in future years your irrigation needs change, and harder to fine-tune greywater flow to each irrigation zone. |
