The main functions of the PP rainwater module include rainwater collection, storage, and regulation. Before the rainfall reaches a high level, the rainwater in the collection pond is slowly drained, temporarily maintaining the peak flow rate of the runoff. This method can avoid the rainwater flood peak, achieve the reuse of rainwater, and also prevent the initial rainwater from polluting the receiving body of water, while also having a positive effect on flood control and scheduling.

The function of the PP Rainwater Collection Module:

1. The rainwater collection PP module's rainwater pollution and purification function: During the daily rain, as raindrops hit the ground, the PP module transfers initial waterway debris in the surface area for automatic disposal, conveying floating matter and large-volume objects in the rainwater sediment to prevent clogs in pumps, drainage pipes, and various piping systems. The popular rainwater collection PP module system stores rainwater in the PP module water storage tank, then uses the natural treatment device of the distribution system under the influence of waste flow gravity to settle floating matter, especially settleable solids, separating rainwater and clarifying water quality.

2. The PP module's water recycling function after filtration, collects and stores natural rainwater in the PP module water storage system. After the salt is dissolved and the poison is filtered through the purification system, it can be used for underground water layer drainage pipes, road sprinkling, water feature recirculation, and balanced lawn irrigation. Additionally, rainwater can be infiltrated below the reservoir using a pressure control pump to supplement groundwater resources and improve the ecological environment.

3. The function to improve the pressure of the water circulation system; the rainwater collection PP module can enhance soil and water quality, ensure free exchange of water flow, improve the ecological environment, significantly reduce groundwater extraction, and also alleviate the pressure on the overall groundwater circulation system, highlighting the advantages of the durable rainwater collection PP module.
