(1)Catchment Area ? Roofs (residential, industrial, public buildings) ? Ground surfaces (squares, roads, green spaces) ? Other hard surfaces (e.g., parking lots);(2)Diversion System ? Gutters and downspouts: Direct rainwater into storage devices. ? Initial diversion devices: Filter out initial rainwater (which may contain pollutants).(3)Filtration System ( ? Coarse filtration (e.g., screens, sedimentation tanks) removes large particles like leaves and sediment. ? Fine filtration (e.g., sand filters, activated carbon) improves water quality for higher-demand uses.;(4)Storage Facilities ( ? Above-ground storage tanks (plastic, metal, or concrete) ? Underground storage tanks (modular storage systems, space-saving) ? Rain barrels (small-scale household systems);(5)Purification Treatment (optional) ? Ultraviolet (UV) disinfection: Kills bacteria, suitable for non-potable uses requiring higher water quality. ? Reverse osmosis: Further purification for uses like car washing or industrial cooling.;(6)Water Supply System? Water pumps: Transport stored rainwater to points of use. ? Pipeline network: Connects to uses such as irrigation, toilet flushing, and industrial cooling.

Eco-porous fiber cotton and carbon fiber rainwater collection modules do not expand or deform after absorbing water, with a load-bearing capacity of 5-25 tons per square meter, preventing collapse. Since the product is made of rock-based materials and its properties are similar to soil, its water release rate closely mimics natural soil, slowly releasing water into the ground as needed. This characteristic prevents rainwater from accumulating underground. The load-bearing capacity of the surface it supports is closely related to its burial depth and the upper fill materials, such as soil, gravel, or pebbles. Traditional synthetic buffers are prone to surface damage and overall collapse.
