Why Choose Our Modular Rainwater Tanks?

Our rainwater tanks feature an innovative modular design, allowing for flexible configuration and expansion based on your specific needs (e.g., collection area, water consumption, and installation space). Whether for a small residence, community project, or large commercial facility, we offer the perfect size and layout, offering flexible installation and adaptability. Precision-engineered and manufactured from high-strength materials, these modular units offer excellent pressure resistance and can be safely buried beneath green belts, roads, or parking lots, maximizing underground space without impacting surface planning. Our rainwater tanks are constructed from food-grade, environmentally friendly PE or high-strength PP materials, offering corrosion resistance and a long lifespan. The structural design facilitates inspection and cleaning, minimizing maintenance costs.

Installation Steps

1. Site Preparation

1.Survey the Site: Conduct a site survey to assess the conditions (e.g., soil type, water table, traffic load) and determine the optimal installation location.
2.Excavation: Excavate the ground to the required depth and size to accommodate the modules. The trench should be wide enough to allow for proper installation and water flow.
3.Level the Base: Ensure the base of the trench is level and compacted to provide a stable foundation for the modules.

2. Foundation and Bedding Layer

Install Bedding Material: Lay a bedding layer (usually crushed stone or gravel) at the bottom of the trench. This ensures proper drainage and provides support for the modules.
Compact the Bedding: Compact the bedding material to create a firm base for the modules, ensuring a stable, uniform surface.

3. Stormwater Attenuation Tanks Placement

Position Attenuation Tanks: Carefully place the Modular Rainwater Tanks into the trench. Ensure that the tanks are aligned properly and the connectors (if applicable) are facing the correct direction.
Stacking (if applicable): If stacking is required, ensure that the rainwater attenuation tanks are stacked in a stable and secure manner, following the hualin guidelines.

4. Stormwater Attenuation Tanks Connection

Connect Stormwater Attenuation Tanks: Depending on the system design, connect the Stormwater Attenuation Tanks using interlocking mechanisms or connectors to ensure the system is secure and watertight.
Connect to Drainage System: Link the Stormwater Attenuation Tanks to the surrounding stormwater drainage system, ensuring proper inlet and outlet connections for water flow.

5. Backfilling

Backfill Around Tanks: Once the tanks are in place and connected, backfill the trench with appropriate material (e.g., gravel or sand) around the tanks. Avoid using materials that could cause compaction or block water flow.
Compact the Backfill: Gently compact the backfill to ensure stability without damaging the tanks.

6. Installation of Surface Layer

Reinforce Surface: Install a surface layer (e.g., asphalt or concrete) above the stormwater attenuation tank system, depending on the application (e.g., road, parking lot, or green space).
Ensure Proper Drainage: Make sure that the surface layer allows for proper water drainage into the tanks. This is particularly important for areas like roads or parking lots.

7. Final Inspection & System Testing

Inspect Alignment & Connections: Ensure all tanks are properly aligned, with secure connections and no gaps.
Test the System: Simulate rainfall or runoff to verify water flows correctly through the tanks, checking for any leaks, blockages, or drainage issues.

8. Maintenance and Monitoring

Establish Maintenance Schedule: Set up a regular inspection and cleaning schedule to ensure the system continues to function optimally.
Monitor for Damage or Blockages: Check the system periodically for signs of damage or blockages and address any issues promptly.
