Stonehouse Water Technologies, a Milwaukee-based startup developing energy-efficient water purification systems, said it raised more than $1.5 million from investors. Launched in 2012, Stonehouse is developing a water purifier about the size of a dehumidifier that’s designed for use in residential, commercial, and agricultural properties. According to a press release, the company’s water purification system will be available for purchase starting in early 2018.

Mark Sellers, a former executive at the plastic injection molding business MGS Mfg. Group, led the round, Stonehouse said. Mason Wells, a Milwaukee-based private equity firm, acquired MGS in 2016 for an undisclosed sum.
