"Rainwater Recycling and reuse"

 

Taiwan is a rainy island country, according to statistics Taiwan is rich in water resources, but the rain did not properly interception measures, resulting in each per capita water scarcity, the country is also a high shortage of water crisis, is ranked 18. All public construction in Taiwan, ditch cement replaced the original pebbles of silt, so that the area of impermeable pavement is more and more wide, relatively weak recharge function of groundwater. Taiwan's policy on water resources management, still in the construction of reservoirs and river Weir stage, such a policy not only to build the cost of the system is staggering, the destruction of the ecological environment is also very serious, seemingly progressive approach to the environment so backward.

 

Generally speaking, rainwater is a fairly clean source of water, unless it is a serious area of air pollution, buildings or campuses should plan and use roofs as rainwater harvesting areas, and then dispose of rainwater properly and in storage. and set up two Yuan water supply system (that is, tap water and rainwater respectively used in the pipeline), rainwater as a miscellaneous water, such as flushing toilets, watering, supplementary air-conditioning water or landscape pool and ecological pool of supplementary water. Therefore, rainwater utilization measures can save precious water sources and reduce water charges, so as to truly implement the target of effective utilization.

 

This time our Minglun team to visit the "safe countryside" has rainwater harvesting equipment. A total of four rainwater storage barrels, each 10 metric tons of capacity, a total of 40 metric tons. Rain before the use of sand filtration and ultraviolet sterilization before used for irrigation or fertilization, although the capacity is limited, but to reduce the extraction of groundwater is still a great help.
