Participation of 4 Companies Including Suido Kiko: Completion of the 'Masaki Town Water Purification Facility Construction Project'

Suido Kiko Kaisha, Ltd. (Headquarters: Setagaya-ku, Tokyo; President: Toru Furukawa; hereinafter 'Suido Kiko'), whose main business is the design, construction, and management of water and sewage facilities, as well as environmental conservation and sanitation facilities, participated in the completion ceremony of the 'Masaki Water Treatment Plant (Masaki Town Water Purification Facility Construction Project)' held on Saturday, March 28, 2026. For the construction of this facility, we built a strong cooperative system with experts in each field: 'Nakanihon Engineering Consultant Co., Ltd.' in charge of design, 'Ichimiya Komuten Co., Ltd.' in charge of construction work, and 'Masaki Kensetsu Co., Ltd.' in charge of on-site piping and site development work.

The Masaki Water Treatment Plant was constructed as part of the 'Masaki Town Waterworks 6th Expansion Project' to address issues such as changes in source water quality and large-scale earthquakes. It handles the water supply for the Masaki and Nishikoizumi blocks, which target the largest water supply population in the town, and is a facility capable of treating 7,550 cubic meters of water per day. The treatment method for this facility adopts 'Membrane Filtration Equipment for Water Supply' that brings together the membrane technology of Toray Industries, Inc., ensuring a stable supply of safe and secure water by reliably separating and removing impurities from the raw water.

Moving forward, through our long-cultivated water treatment technology and the introduction of equipment such as the latest membrane filtration systems and emergency power generators like the ones used this time, Suido Kiko will continue striving to stably deliver safe and high-quality water, addressing changes in source water quality and disaster countermeasures.
