A subsidence water storage device for landscaping maintenance irrigation system

technical field

The invention relates to the technical field of irrigation systems, in particular to a subsidence water storage device for an irrigation system for landscaping maintenance.

Background technique

With the development of urban construction, the landscaping area is getting larger and larger, requiring a large amount of irrigation water. Regardless of whether the city's tap water is used directly or the water in the river is transported by tanker trucks, the cost of irrigation is relatively high. Combined with the development of the sewer pipe network, using urban rainwater as the water source for landscaping can automatically irrigate the landscaping in a certain area, saving tap water and reducing irrigation costs. The urban rainwater irrigation system needs to have a certain storage capacity, and the rainwater collected by the sewer pipe network cannot be used directly. After simple filtration, the rainwater will still carry more impurities, which is easy to block the irrigation pipes. In the process of storing the pre-filtered rainwater in the pool, silt or scale will be generated at the bottom of the pool, which is difficult to clean up manually and the cost of cleaning is relatively high. It is necessary to design a rainwater settlement device, which can be used for irrigation at low cost while storing water. Provide clean water.
