Detailed Product Description



      Rainwater module tanks are part of the rainwater collection system for sponge city construction and can effectively infiltrate, intercept, store, purify, utilize and discharge rainwater. The rainwater resources collected by the rainwater module can be used for flushing toilets, watering sidewalks, watering lawns, watering water features and firefighting. In addition, it can be used to supplement water resources and alleviate water shortages in cities.

Rainwater Module Tanks Application:

      Building rainwater collection system: It is suitable for collecting rainwater from the roof of buildings, parking lots and other areas. By installing rainwater collection modules, rainwater from these areas can be collected and used for toilet flushing, irrigation and so on.

      Urban Green Space Infiltration and Drainage System: Structures such as recessed green belts or grass-planted trenches are designed in urban green areas to utilize the absorptive capacity of the soil and vegetation to perform preliminary filtration of rainwater and discharge it into the rainwater harvesting module for further treatment.

      Road runoff control: Collecting rainwater by installing permeable paving materials on roads or through a network of underground pipes and directing it to rainwater harvesting modules for storage. This approach helps to reduce waterlogging on roads and improve driving safety.

      Rainwater Reuse in Residential Areas: Roof gardens and ground infiltration devices are established in residential areas to collect and utilize rainwater as a non-potable source of water for landscaping and miscellaneous domestic drainage. Rainwater harvesting modules can be used as a core component of these systems to provide a stable water supply.

      Rainwater Harvesting Project for Public Buildings: Rainwater harvesting modules are installed in parks and squares as well as large public facilities such as parking lots to store and redistribute rainwater resources. These modules can be combined and assembled according to the actual demand to form different sizes and shapes of water storage tanks.

      Industrial Cooling Water Replenishment Application: Industrial areas can utilize rainwater collected by rainwater collection modules as one of the water sources needed for equipment cleaning and cooling and for replenishment during industrial processing. This approach helps to reduce the operating costs of enterprises and improve the efficiency of water utilization.
