Drainage of the agricultural pond is implemented inexpensively using siphon drainage! Achieving a drainage rate of 2m³ per minute with a φ100mm device!
A company that was considering lowering the water level in a reservoir in Iga City, Mie Prefecture, contacted us regarding the hybrid Yamata siphon. Considering the local conditions, we installed a φ100mm siphon drainage system. Through siphon drainage, we were able to lower the water level of the reservoir, which is 100m wide and 100m deep, by 20cm per day. The site was inaccessible to large machinery, so transportation and installation were carried out using a small all-terrain transport vehicle and seven workers. Additionally, due to the difficulty of transporting a 4-inch submersible pump and a three-phase generator for starting the siphon, we used three 2-inch submersible pumps and a portable generator that could be carried by hand to initiate the siphon. With a 100m extension of the piping and a height difference of 10m between the water level in the reservoir and the discharge outlet, we achieved a drainage rate of 2m³ per minute with zero fuel consumption through siphon drainage. This drainage rate of 2m³ per minute was comparable to that of a φ150mm submersible pump powered by electricity.

Yamachin Group is supported by the understanding and guidance of many people, and with the corporate philosophy of "creativity, ingenuity, and tireless effort," we are committed to contributing to the local community alongside the development of our company. By engaging in civil engineering projects that involve nature, we consider how to conduct construction with respect for the natural environment, learn many lessons from it, and aim to create a "distinctive company" among numerous construction contractors. In 1991, we established the Environmental Division and began "environmental conservation activities unique to the construction industry," developing and proposing various environmental products such as natural stone block series for river environment conservation, various fishway series tailored to installation locations, and the "Hybrid Eco Pump," an underwater pump that operates without electricity. We have worked on promoting and raising awareness of environmentally friendly construction methods. Thanks to this, we have been adopted in numerous projects, and we are grateful to be contributing to environmental conservation. Yamachin Group will continue to take on challenges through the construction industry, working on "proposals dedicated to the natural environment of our hometown" and contributing to global environmental conservation.
