Rainwater utilization

Rainwater utilization refers to the process of collecting, storing, treating, and reusing rainwater that has fallen to the ground. Rainwater utilization is mainly applied in urban greening, agricultural irrigation, landscape water replenishment and other fields, effectively reducing dependence on traditional water sources such as groundwater and tap water, and providing strong support for urban sustainable development.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The water cycle refers to the continuous and cyclical movement of various forms of water on Earth through processes such as evaporation, water vapor transport, condensation, infiltration, and runoff, under the influence of solar radiation, Earth's gravity, and other factors (the process of water phase transformation). For example, the water on the ground is evaporated by the sun into water vapor in the air. The state of water on Earth includes solid, liquid, and gas. Most of the water on Earth exists in the atmosphere, ground, underground, lakes, rivers, and oceans. Water can move from one place to another through physical processes such as evaporation, precipitation, infiltration, surface and subsurface flow. The various forms of water on the Earth's surface are constantly transforming into each other. The process of water circulating in gaseous, liquid, and solid forms between land, oceans, and atmosphere is called the water cycle. The water on the Earth's surface undergoes morphological transformation and migrates in the surface and adjacent spaces (troposphere and shallow subsurface). according to.
