Rainwater harvesting is the English "Rain Harvesting", which means the same as harvesting rainwater harvesting crops. Compared with the traditional rainwater harvesting resources with multiple functions: green energy, which will help save water, to mitigate water crisis; increased groundwater by infiltration, improve the ecological environment; rain displacement reduction and mitigation, to reduce urban stormwater disasters. Construction is to use rainwater in the sky rain water cycle natural terrain or artificial methods to collect, closure, storage, treatment and reuse for residential construction and daily use of water. Rainwater harvesting combination of technology and residential construction will change our lives because of the increasing depletion of water resources to a large extent. We use rainwater sponge Shenzhen Technology Co., after four years of casting international quality, specialized in the production and sale of rainwater collection system, drainage system equipment. The company doing PP plastic rainwater collection module, drainage module, rainwater infiltration module, pp rainwater collection tank, plants fixed module, the drainage board. PP rain module has the following features: rainwater tanks to collect rainwater from multiple modules. 1 capacity: PP rain module in standard modular design, can be designed into a variety of shapes and sizes according to the project. From a fundamental change in the conventional basin subsidence, cracking, leakage and other problems. 2, rainwater collection simple and quick: PP rainwater module to collect rainwater from roofs, gardens, lawns, paved areas and driveways to increase water storage and supply capacity. Owns 95% of the reservoir porosity rate, and more than 6 tons of compressive strength. . 3, saving time and effort; PP module rainwater quickly assembled without tools, dramatically reducing the use of construction machinery and construction strength. Installed in the ground, set in green on demand, roads, squares, parking lots, playgrounds underground, do not take up floor space, and will not affect the landscape effect. 4 Water storage capability: rain rain PP module before entering through the abandoned flow, filtration, water module is maintained under optimal conditions, and there is enough space for aerobic activities. This prevents stagnant due to rain and water quality impacts of anaerobic bacteria. 5, environmentally friendly products: 100% recycled material (polypropylene) manufacturing, safety and no pollution. 6, garden reservoirs: PP module can create maintenance of rainwater storage reservoirs, year round to collect rainwater for watering landscaping provide a lot of water. Comparison of traditional irrigation methods, can save a lot of money on. Material: 100% recycled environmentally friendly PP (polypropylene) gap: 50 to 70 spaces chemical and biological resistance: from soil, algae, soil microbes, bacteria and other items affecting asphalt temperature: -30 ℃ to 120 ℃ Compressive strength: 151.28 T / m water flow rate: 105Ltrs / min
