Rainwater storage tank - Plastic rainwater storage infiltration facility "Pradam-kun"
High storage capacity with a porosity of over 95%! Excellent seismic strength and easy to assemble.
"Pradam-kun" is a rainwater storage tank that has a significant retention effect due to over 95% void space (in cases where the facility height is 1.2m or more), reducing excavation and residual soil volume, thereby lowering total costs. The accumulated sand and other materials can be easily removed using an inflow device, making maintenance simple, and it can be installed under parking lots due to its excellent compressive strength. 【Features】 ◆ Achieves high water retention with over 95% void ratio! (in cases where the facility height is 1.2m or more) ◆ Excellent seismic strength, usable even under parking lots! ◆ Main components are one part, and assembly is completed by simply connecting dedicated joints! ◆ Usable for both storage and infiltration facilities! *For more details about the product, please download the catalog or contact us.
basic information
【Product Features】 ■Easy Maintenance →Installed a "Sediment Tank and Non-Dust System" as an inflow tank Easily maintainable by removing the sand accumulated in the inflow tank without allowing soil particles to enter the storage tank. ■High Porosity of Over 95% →Ensures a practical porosity of over 95% after assembly (for facilities with a height of 1.2m or more). ■Cost Reduction →Reduces excavation and residual soil volume due to high porosity, thereby lowering total costs. ■Simplification of Construction Work →Each unit weighs only 6.8 kg, making assembly easy by simply connecting dedicated joints. ■Sufficient Compressive Strength →Compatible with T-25 load, suitable for installation in areas requiring strength, such as under parking lots. It meets Level 2 seismic motion and has sufficient earthquake resistance. ■Reliable Performance and Quality →Obtained technical evaluation certification from the Public Interest Incorporated Association for Rainwater Storage and Infiltration Technology. Certification updated as of April 1, 2019. ●Construction Status and Installation Example Photos ●Layout and Structural Diagrams ●Photos, Dimensions, and Materials of Each Component ●Introduction of Associated Facilities such as Inflow and Inspection Facilities for "Pradam-kun" For more details on the "Rainwater Storage and Infiltration Facility / Rainwater Storage Tank 'Pradam-kun'," please refer to the 【Download Catalog】.

It was selected for the JICA 2017 project formulation survey.
In the fiscal year 2017, our proposed project "Feasibility Study on Plastic Rainwater Storage Structures" targeting Thailand was selected for the "Support Project for Overseas Expansion of Small and Medium Enterprises - Feasibility Study" by the Japan International Cooperation Agency (JICA). The contract was signed on August 18, 2017. In Thailand, which experiences heavy rainfall, flooding damage occurs frequently, and the lack of sewerage and drainage facilities is a significant issue. The impact of the 2011 Thailand floods on the Japanese supply chain is still fresh in our memories. This study will investigate the actual conditions of flooding damage, rainwater utilization, and ground conditions, primarily in Bangkok, and will examine the feasibility of deploying plastic rainwater storage structures.
