Metawater

Metawater builds and runs water for a living. The company was created on April 1, 2008 by merging the water-environment arms of two Japanese industrial names, NGK Insulators, which brought ceramic-membrane and mechanical know-how, and Fuji Electric, which brought the electrical and control side, making it the first Japanese firm to fuse machinery and electricity in water treatment. Metawater is an operating company first and an investor second, the engineer that designs, builds, and maintains a large share of Japan's municipal water and sewage plants.

Metawater invests the way industrial companies do, for strategic fit rather than financial return, which is why (don't) Waste Water classes it as a Strategic Corporate backer and rates its water commitment Occasional. It puts money into technology that plugs into its own plants, not into a broad venture portfolio. Its two tracked water bets fit that pattern exactly: WOTA, the Tokyo startup whose small, self-contained units recycle water on site without mains pipes, and Novity, a Silicon Valley spinout whose AI predicts when industrial equipment will fail before it breaks.

As of April 2025, Metawater completed its acquisition of Schwing Bioset, a US specialist in sludge and biosolids handling, folding it into Metawater USA alongside Aqua-Aerobic Systems. Metawater's sharpest moves are acquisitions, not venture cheques, and the Schwing deal shows where the money tends to go: buying proven hardware companies that widen what its plants can do, in this case across North America.

Metawater is the investor a water founder meets when the product is really plant infrastructure, a membrane, a control system, a treatment module a utility would install for decades. It backs technology it can sell through its own engineering business, often beside other Japanese strategics such as Mitsui and ShinMaywa Industries, which makes it a patient, deeply technical partner rather than a fast-moving financial one.
