Introduction to "Koiwai's Waterside Greening"

We are working on the restoration and creation of waterfront environments from the perspective of plants with a broad vision!

Our company is engaged in the following activities through the utilization of waterfront plants: 1. Proposals for river development and eco-enhancement of waterfronts 2. Wastewater treatment using plants 3. Wastewater treatment through constructed wetlands 1. By planting waterfront plants, we propose various benefits, including the formation of ecotones, habitats for wildlife, and nurseries for small fish, as well as the creation of landscapes. 2. Focusing on the water purification functions of waterfront plants, we are primarily working on the technological development of horizontal flow wastewater purification systems using bulrush and reeds. 3. We are also incorporating hybrid artificial wetlands that combine vertical and horizontal flow, which significantly expands the range of wastewater treatment options and enables responses in various settings. *For more details, please download the PDF or feel free to contact us.
