In recent years, as a measure against flooding and ground subsidence, many municipalities have begun to require the installation of rainwater runoff control facilities during construction and development activities. However, the required measures differ from one administration to another, and the methods for calculating infiltration rates also vary, making this complexity a significant burden for those in charge of design. Our company possesses extensive know-how regarding the planning and calculation of rainwater runoff control facilities for the "Rainwater Retention and Infiltration Facility 'New Trench-kun' and 'New Pla-kun'," which we have developed through discussions with various administrations. Based on this expertise, we offer a service for creating rainwater calculations tailored for design professionals.

In accordance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology, we have launched a model-changed new standard "New Trench-kun II" (product dimensions remain unchanged). Improvements have been made compared to the conventional model as follows: - Compliance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology - Improved connection pieces for easier assembly - Elimination of transport pipe ribs, allowing for internal inspection of the tank with a camera The plastic rainwater retention and infiltration facility, infiltration trench "New Trench-kun II," significantly reduces construction area with its excellent void ratio. No piping work is required, assembly is extremely simple with one-touch connections, and construction time is shortened. It is compatible with T-25 and can be installed under parking lots. The unique internal maintenance function of New Trench-kun II makes maintenance very easy. Due to these features, a cost reduction of 0-40% compared to conventional crushed stone trenches is possible (this varies by administration, so please contact us for details). *New Trench-kun II is a previously registered product in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system 'NETIS' (old registration number KT-130092-A).
