I work as a freelance electrical engineer to build this equipment.

During the process of redirecting the water underground, Land Engineering Consultants Ltd (abbreviated as LEC) normally use an very heavy and outdated equipment made by OYO.

Despite OYO had already discontinued its development and support few years ago, LEC couldn't find any better solution to replace that OYO machine. They also worried about the machine will stop working someday.


After understanding the problems from LEC, I started designing a new device later called GWL-01. Using similar principal as the existing device, I managed to build a much smaller/lighter device and it can just use the power from a laptop(the OYO one needs to use a car battery and weigh 20kg)
