Stormwater Infiltration Drains

Eco-friendly PP material, space-saving design, high permeability, ideal for urban drainage, enhances groundwater recharge, optimizing project efficiency.

The increasing sealing of land surfaces has led to significant challenges, such as rising stormwater drainage costs and flood damage. This has prompted a rethinking of stormwater management, shifting from centralized treatment to decentralized infiltration, where excess rainwater is absorbed on-site. Stormwater infiltration drains play a crucial role in this approach, designed to mitigate surface runoff by allowing rainwater to percolate into the ground, thus recharging groundwater, reducing flooding, and filtering pollutants.

Constructed from environmentally friendly polypropylene (PP) through a single-step injection molding process, these drains serve as vital components of urban drainage systems. They modify traditional rainwater pipes into perforated infiltration pipes, facilitating effective drainage with minimal space usage. Gravel backfill around these pipes enables rainwater to infiltrate the soil efficiently, and their skeletonized plastic modules offer up to 95% clearance for optimal water flow.

Authorities in Germany and other countries increasingly advocate for decentralized infiltration measures, promoting them through reduced wastewater charges and subsidies for unsealing and infiltration initiatives. With Yude’s complete range, ensuring the successful implementation of sustainable stormwater management projects, we provide you with a unique all-round service for the success of your project.

Advantages of rainwater Infiltration Drains

  1. Flexible Connections: Infiltration drains can be connected individually or in conjunction with other drainage facilities, providing a high degree of design and application flexibility.
  2. Water Flow Dredging and Groundwater Recycling: These drains not only help to divert surface water flow and prevent ponding and flooding, but also support rainwater infiltration and increase groundwater recharge for water recycling.
  3. Wide range of application scenarios: Infiltration drains are suitable for use in a variety of settings, including green areas, permeable pavements, small car parks, industrial areas and residential areas, providing effective stormwater management solutions for cities.
  4. Increased stormwater retention: installing infiltration drains underneath grassed swales can expand the amount of stormwater retained and reduce stormwater runoff, thereby reducing pressure on downstream water bodies.
  5. Enhanced Infiltration: Infiltration swales can be configured under bioretention ponds and rain gardens to enhance surface water infiltration and purification, improving water quality in the area.
  6. Multi-functional combination: Infiltration trenches can be combined with a gravel infiltration layer to increase storage space and improve infiltration efficiency. This combination is particularly useful in narrow municipal roads and back green spaces.
  7. Environmentally friendly: by increasing groundwater recharge and improving water quality, infiltration drains have a positive impact on environmental sustainability and ecological balance.

Stormwater Infiltration Drains installation process

  1. Site Preparation: Clear the area of debris and vegetation. Ensure the site is level and has proper drainage patterns.
  2. Excavation: Dig a trench or pit according to the specifications of the infiltration system. The size will depend on the design and anticipated water flow.
  3. Base Layer: Place a layer of gravel or crushed stone at the bottom of the excavation to facilitate drainage and support the infiltration pipe.
  4. Pipe Installation: Position the perforated infiltration pipe (drain) within the trench. Ensure the perforations are facing downward for effective infiltration.
  5. Backfilling: Surround the pipe with additional gravel, covering it adequately to promote water flow while allowing for infiltration. Leave space for soil cover if needed.
  6. Final Grading: Level the top layer of soil to ensure proper runoff toward the infiltration system.
  7. Vegetation (optional): Plant grass or other vegetation over the system to enhance aesthetics and further improve infiltration.
  8. Maintenance Access: Ensure access points for future maintenance and inspection are included in the design.
