Technical implementation 

The rainwater storage system is designed to 200 cubic adjustment ponds, and two 100 cubic adjustment ponds are used to meet the requirements. The period of project construction is 8 days, and the main components: Germany imported centrifugal device, abandon flow filter well, glass fiber reinforced plastic rain adjusting pool, jet pump, water pump and drainage pump group, automatic electric control integrated system.

Application effect

Compared with the cost of steel and concrete, the cost of the FRP is 105,000 yuan, and the FRP storage tank can last up to 70 years, the product is covered with soil and the road is hardened to ensure to meet the design requirements. When the flow of rainwater is large, it flows into the glass-steel-adjusting pool, temporarily storing the peak rainwater in the pool, and then discharging the rainwater to the municipal network after the flood peak has subsided. 

The 320,000 yuan glass reinforced plastic rainwater infiltration system is used to handle 22,400 tons of water. The outdoor green water was 19,260 tons and the landscape water was 2,970 tons. The electricity consumption is 6,416 degrees. The cost of electricity consumption is 5,456 yuan and the cost of rainwater recovery is 48,020 yuan.
