Roof rainwater utilizing system

Abstract

The invention discloses a roof rainwater utilizing system. The roof rainwater utilizing system comprises an eave gutter, a rainwater hopper, a vertical rainwater pipe, a filter, a rainwater collecting pipe, a rainwater storage tank, a water pump and a water supply hose, wherein the rainwater hopper is arranged at a lower position of the end part of the eave gutter of a house, the upper end part of the vertical rainwater pipe is connected with the lower end part of the rainwater hopper, the lower end part of the vertical rainwater pipe is connected with an upper port of the filter, the upper end part of the rainwater collecting pipe is connected with a lower port of the filter, the lower end part of the rainwater collecting part is connected with a water inlet pipe of the rainwater storage tank, a water inlet of the water pump stretches into the inner part of the rainwater storage tank, and the water supply hose is connected with a water outlet of the water pump, and extends to the ground. Rainwater collected and filtered by the system is applicable to general applications such as irrigation, greening, toilet flushing and the like; and good-quality tap water is saved.

Description

technical field [0001] The invention relates to a rainwater utilization system, in particular to a roof rainwater utilization system. Background technique [0002] At present, municipal tap water is still used as the water supply source for greening of most buildings, and it is a great waste to use tap water with good water quality as greening water, which aggravates the shortage of water resources. At the same time, a large number of rainwater collected by the roofs of many buildings has not been effectively utilized. The rainwater is of good quality and can be used for general purposes such as greening after simple treatment with low-cost processes. It is relatively low, and most of them enter the sewage treatment plant through the drainage system for centralized treatment. These high-quality water sources that can be treated at low cost and sewage must be treated with complex processes after being mixed, which increases the cost of water treatment and is also a great reso...
