Water Solution Provider

Nihon Rensui Corporation, our predecessor, was established in 1952 and is a comprehensive water treatment company that provides a one-stop service from drinking water to wastewater, offering a variety of water treatment-related proposals to customers in various fields.
We offer pure water production equipment using ion exchange resins and ion exchange membranes, beverage production equipment utilizing groundwater, separation and purification equipment for pharmaceutical and food materials, wastewater treatment equipment applying membrane separation activated sludge method, and design, manufacturing, construction, and maintenance of medical water production equipment for hospitals. Furthermore, in 2021, we launched a plant factory business selling hydroponic cultivation systems, advancing towards a circular economy of water and resources.

Among these, our Wellthy division serves as a pioneer company in groundwater membrane filtration systems (beverage systems), providing services that ensure the water lifeline even during water shortages caused by disasters, to over 1300 public facilities, hospitals, nursing facilities, commercial facilities, factories, educational institutions, and more nationwide. Wells have been proven to be less susceptible to earthquake damage in past disasters, and groundwater membrane filtration systems serve as effective preparations for securing lifelines during disasters.
We are committed to contributing, albeit in a small way, to disaster preparedness efforts through this system.
