Integrated Rainwater Harvesting Underground System

The buried integrated rainwater collection system collects rainwater from rooftops and pavements as per demand, treats it to meet water quality standards for reuse, thereby reducing the city's reliance on tap water. The rainwater processed by this system also complies with national energy-saving and environmental protection requirements.

Trench-mounted Integrated Rainwater Harvesting System Overview

The buried integrated rainwater collection system collects roof and road rainwater as per requirements, treats it to meet water quality standards for reuse, reducing the city's consumption of tap water. The rainwater processed by this system also complies with national energy-saving and environmental protection standards.

Subsurface Integrated Rainwater Harvesting System Process Flow

Collected rainwater flows through the urban drainage network to the overflow system via storm drain wells. The overflow system automatically discharges initial rainwater, with water meeting treatment requirements entering the storage and regulation system. The water in the storage system is purified by the rainwater treatment unit before entering the clean water system. Once the water quality in the clean water system meets usage standards, it is then transported to various water points by the reuse equipment. Depending on the water quality requirements of the reuse points, additional dosing and disinfection units can be installed. Additionally, a small amount of impurities generated during treatment and excess rainwater that the system cannot handle promptly are discharged as overflow into the downstream pipeline through overflow wells.

Advantages of Underground Integrated Rainwater Collection Equipment

1. Subsurface integrated rainwater collection system, without affecting the landscape. It is completely buried and occupies a minimal footprint.

2. Excellent water output quality, meeting the users' water requirements.

3. The system features multimedia purification with strong backflow resistance, strong deodorization, stable water quality output, low backflush water usage, and a long purification cycle.

4. The system features an integrated clean water tank and variable frequency pressure pump unit, capable of meeting the user's requirements for constant pressure water supply for landscaping irrigation or toilet flushing, thereby saving on construction investments.

The application of buried integrated rainwater collection systems can be utilized in urban communities, parking lots, gardens, sports fields, and other areas for rainwater collection. The collected rainwater, while not suitable for direct drinking, can be used for bathing, laundry, flushing toilets, washing cars, etc. It helps save costs for businesses with high water consumption, such as car washes, water clubs, and golf courses.

Widespread utilization of buried integrated rainwater collection systems nationwide has promoted the effective use of rainwater resources, minimized the impact of urban development on the ecological environment, and achieved the ambitious goal of 70% local consumption and utilization of rainwater. Enhancing the quality of urbanization and promoting green and low-carbon urban development is of great significance.
