For the decrease in water level of the agricultural pond! A siphon drainage system with zero fuel costs!
Developed a siphon drainage system that allows for zero fuel costs and can be manually transported to prevent water level decline and dam failure! Drainage using the principle of siphoning can be easily activated!
This is a device that easily initiates drainage due to a decrease in water level in places with elevation differences, such as agricultural ponds, using a suction hose and dedicated components. Because it operates on the principle of siphoning, fuel costs are nearly zero. This allows for significant cost reductions in fuel expenses, and it also reduces the hassle of refueling. The device with a diameter of 100mm can be transported manually and can be installed in locations where heavy machinery cannot access. The greater the elevation difference, the more drainage capacity increases; in practice, the 100mm device has recorded drainage rates of over 2m³ per minute. This is roughly equivalent to the drainage volume achieved using conventional 150mm submersible pumps powered by electricity.

basic information
For drainage based on the principle of siphoning, it is a condition that the installation position of the drainage outlet is lower than the water level of the reservoir. Additionally, it is also a condition that the height of the top of the dam, which is the highest point of the piping relative to the water level of the reservoir, is 7 meters or less. The discharge amount varies depending on the length of the piping and the difference in height between the water level of the reservoir and the height of the discharge outlet for siphon drainage, but as a rough guideline, a height difference of 4 meters or more is desirable. The installation of the device depends on the conditions of the installation site, but for a piping extension of 100 meters, it can be installed in about half a day by a team of five people. The suction hose with dedicated connection fittings is available for purchase, while other dedicated components are available for rent. Please feel free to contact us for estimates and other inquiries. To initiate the siphon, a submersible pump, generator, etc., will be used for the first few minutes. We kindly ask you to prepare the generator and submersible pump.

Applications/Examples of results
- Fresh valley water was supplied to the fish tank of a ryotei (traditional Japanese restaurant) near the construction site through siphon drainage. This supply was maintained for about seven months without using any fuel, achieving significant cost reductions. - In a construction project at a reservoir in Mie Prefecture, this device was adopted due to the lowering water level of the reservoir. Since the site was inaccessible to heavy machinery, materials were transported using a small all-terrain vehicle and manual labor for installation. The site conditions were favorable for siphon drainage, resulting in a pipe extension of 100 meters and a drop of 11 meters, measuring a drainage rate of 2.1 m³ per minute, achieving water level reduction at a low cost. - This device was adopted at a reservoir in Kyoto Prefecture due to the lowering water level. Installation was carried out using a small backhoe and manual labor. With a pipe extension of 80 meters and a drop of 10 meters, a drainage rate of 1.7 m³ per minute was achieved, resulting in water level reduction at a low cost.

Company information
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.
