Rainwater Harvesting and Utilization – Several Method of Roof Rainwater Utilization
What is roof rainwater utilization?
Roof rainwater utilization is a kind of rainwater utilization method, which uses roofs or other buildings to collect rainwater. Urbanization interferes with the natural hydrological cycle, resulting in a large loss of rainwater. It is also a remedy for the damage of natural water circulation by pouring rainwater into the underground water after collecting rainwater. Besides, the water quality of roof water is relatively good, and the rainwater recovery and utilization cost is low, so it can be reused with simple filtration.
Method of roof rainwater utilization
1. Use green building to harvesting rainwater
It is widely used to use Drainage Plate to plant green plants on rooftops or buildings. Using green buildings to harvesting rainwater can reduce the consumption of tap water, increase the green area of the city, beautify the urban environment, clean city air, absorbing urban noise and reduce the urban heat island effect.
2.Using rainwater harvesting module to building a roof rainwater system
Install rainwater pipes and other equipment on roof to store rainwater from roofs in Underground Water Tank, reuse after sterilized and filtration. The method of rainwater utilization is relatively high, but it can be considered as a way to construct rainwater collection system for water quality requirements.
City construction of roof rainwater utilization system need according to the condition of different climatic conditions and water resources as well as the size of the available rainfall. Comprehensive analysis of various factors, to design the practical benefits of roof rainwater utilization system, can alleviate the water shortage.
