Introducing various practical examples, starting with "rainwater collection and retention" that gathers and retains rainwater on the premises!
In recent times, with the frequent occurrence of "abnormal weather" and significant changes in rainfall patterns, existing sewer systems and rivers alone are insufficient to manage stormwater runoff. It is necessary to manage stormwater across entire watersheds. Therefore, the role of individual building sites is becoming increasingly important. The "rainwater storage" indicated by the Japan Architectural Institute's environmental standards emphasizes the necessity of efforts for flood control and disaster prevention, which is a key point. Our company engages in "rainwater collection and retention," which involves gathering and storing rainwater on-site, as well as "rainwater management and distribution" and "utilization of rainwater." **Features** - **Rainwater Collection and Retention**: Collecting and storing rainwater to keep it on-site. - **Rainwater Management and Distribution**: Removing debris mixed with rainwater to improve water quality and distributing the stored rainwater to terminal devices. - **Utilization of Rainwater**: Controlling and effectively utilizing rainwater within the building site to contribute to environmental improvement. *For more details, please refer to the PDF materials or feel free to contact us.*
