Rainwater harvesting system

Rainwater Harvesting and Utilization: The Jiayun'er Rainwater Collection System enables the rainwater in the reuse water pump to flush the bottom of the plastic modular assembled reservoir through the flushing pipeline, disturbing the sediment settled at the bottom. Then, by activating the sewage pump, the turbid rainwater is discharged into the downstream municipal sewage network. The buried integrated treatment room is also equipped with a sewage pump, which can remove impurities filtered by the filter.

To prevent the impermeable geomembrane from being punctured by sharp objects such as surrounding stones, which would affect the reservoir's impermeability, the plastic modular assembled reservoir should be wrapped with polystyrene boards before backfilling with earth. Rainwater wetlands generally consist of seven parts: the inlet, forebay, marsh area, outlet pool, overflow outlet, spillway, and maintenance access.

Plants in rainwater wetlands should be selected from flood-tolerant and pollution-resistant aquatic species, such as rushes, willows, foxtail grass, and reeds. To prevent soil erosion from rainwater冲刷, energy dissipation measures using cobblestones are typically implemented at the inlet and outlet of rainwater wetlands.

Rainwater Harvesting and Utilization: The Jiayun'er Rainwater Collection System; a trash rack should be installed in front of the overflow outlet and emptying pipe to prevent impurities from clogging the pipeline. The plastic modular assembled reservoir is a new type of water storage device for rainwater utilization. Its difference from traditional reinforced concrete reservoirs and fiberglass reservoirs lies in the use of plastic modules for water storage, combined with different coating materials to form reservoirs with various functions.
