Reliable water access is vital for urban landscapes as well as residential and industrial use. To support irrigation at a local golf course in Toyota City, Sansui Kaihatsu Co., Ltd., a Japanese underground construction company based in Miyoshi City, Hiroshima Prefecture, completed the drilling of a 250-meter water well using an Atlas Copco Y35 portable air compressor.
Sansui Kaihatsu specialises in underground and boring works, including water wells, geothermal systems, and foundation piling. For this project, consistent airflow and pressure were required to maintain drilling speed through varying ground conditions. The company selected the Y35 compressor for its ability to sustain stable performance throughout the drilling process.
“The Atlas Copco Y35 offers strong airflow and pressure, making it suitable for many of our drilling applications. It has performed reliably and improved our project efficiency,” said Kazuyoshi Ikawa, CEO of Sansui Kaihatsu.
Beyond this golf course application, Sansui Kaihatsu has used the Y35 compressors on a range of projects including hot spring wells, geothermal installations, seismograph drilling, and temporary piling. The company owns two Y35 units, providing flexibility to adapt to diverse projects across Japan.
According to Jaehoon Ahn, Product Marketing Specialist at Atlas Copco Korea & Japan, the Y35’s pressure and flow range make it well-suited to contractors operating in different ground and environmental conditions. “Its versatility allows users to handle varied underground works efficiently, from water wells to geothermal drilling,” he said.
For Sansui Kaihatsu, the Y35 compressors have reduced drilling time and fuel consumption compared with previous equipment. This has improved cost control and reduced downtime on site.
Tatsuo Seko, Sales Engineer at Atlas Copco Japan, noted that reliability and after-sales service are key factors in the company’s relationship with clients. “Our goal is to provide durable machines supported by responsive service, ensuring contractors like Sansui Kaihatsu can maintain productivity over the long term,” he said.
The use of Atlas Copco’s Y35 portable air compressors has strengthened Sansui Kaihatsu’s capacity to deliver dependable water and energy infrastructure projects across Japan. Whether applied in water well drilling, geothermal works, or civil engineering, the equipment provides consistent high-pressure performance to meet the growing demand for efficient, sustainable underground construction.
