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.
