BUILDING RAINWATER HARVESTING AND ECOLOGICAL UTILIZATION SYSTEM

摘要

The present invention relates to the technical field of rainwater recycling. A building rainwater harvesting and ecological utilization system. A drainage funnel is provided in a building downspout. A drainage water pipe is provided below the drainage funnel, and is in communication connection with a municipal pipeline in the ground soil. Both ends of a water harvesting pipe are respectively in communication connection with the building downspout on an upper part of the drainage funnel and the top of a water harvesting tank. Both ends of an overflow pipe are respectively in communication connection with the water harvesting tank and the drainage water pipe. Both ends of an ecological downspout are respectively in communication connection with the water harvesting tank and an ecological water permeable pipe. The beneficial effects of the present invention are: the construction is simple, the processing is easy, the volume is small, and the cost is low. The toxic rainwater is quickly and effectively drained in the early stage. The rainwater is effectively harvested in the middle and late stages. After the harvesting is full, the rainwater can automatically overflow the ecologically nourishing land, and is drained into the municipal pipeline after the soil is saturated to make full use of rainwater resources and ensure the water safety.
