Drainage design for green wall collection trough

Bracket-mounted and made of weather-resistant material, suitable for indoor and outdoor use, it can effectively collect and discharge excess irrigation water.

Featuring a modular design for quick installation, it provides a stable and reliable drainage solution for green wall systems.

A well-designed drainage structure is key to the success of a green wall. In most green wall systems, water moves down the wall and eventually collects and drains out at the bottom. A collection trough ensures this process proceeds smoothly, reducing the risk of seepage, corrosion, or problems caused by plant roots.

This collection trough has been proven in field projects to provide stable and reliable drainage performance, while supporting subsequent cleaning and maintenance operations, reducing management costs and improving the overall performance of the green wall system.

Q: How do I choose the appropriate length for the collection trough?

When selecting the length of the collection trough, decide based on the width of the green wall surface and drainage requirements. The general principle is to allow water to flow smoothly into the collection trough to prevent overflow or stagnation. Large walls can adopt multiple modular segments, while short walls can use a single-segment collection trough; this also makes installation, maintenance, and cleaning easier.

Q: What should be considered during installation?

• Ensure the drainage slope is correct to avoid water pooling or stagnation.
• Modular components must be securely fixed to prevent displacement during use.
• Ensure a tight fit between the collection trough and the drainage pipes to prevent leaking.
• Regularly clean the collection trough to prevent leaves or sediment from blocking the drain.
• If the wall environment is special (such as high temperatures, strong winds, or frequent rainfall), it is recommended to use weather-resistant materials or strengthen the support frame.
