It is possible to carry out construction at a low cost and in a short period of time! This is a groundbreaking system for storing rainwater, realized through joint research with Kyushu University, featuring an "underground" design.
"Tametotto" is an underground rainwater storage tank that collects large amounts of rainwater with a quality comparable to drinking water through a simple construction process over a short period. The rainwater is purified in the gravel layer inside the tank, allowing it to be used safely in a state almost equivalent to drinking water quality. Additionally, this tank has been recognized for its advanced initiatives and has received requests from the United Nations Human Settlements Programme (Habitat). 【Features】 ■ Easy installation, capable of being completed in a short period ■ Can be used safely in a state almost equivalent to drinking water quality ■ Microorganisms living in the gravel purify the water in about two weeks, maintaining a stable quality comparable to drinking water (alkaline) ■ The impact on construction and material costs due to variations in void ratio is minimal ■ Water temperature remains stable around 20°C for almost the entire year *For more details, please refer to the PDF document or feel free to contact us.
