Chinese purified water service provider Fresh Water Group Limited has raised additional capital to build a new manufacturing facility in Xi'an.

In this round of financing, Goldman Sachs joins an investor group that already includes SAIF Partners and Ares Management. The management team of Fresh Water, including founder Shu Xiao, will continue to be the largest stakeholder of the company.

The new factory will triple Fresh Water's existing production capacity, enabling the company to satisfy robust customer demand for its patented Ozner-branded water purification systems.

Fresh Water claims ownership of over 60 patents around its proprietary developed ozone purification technology as well as air filtration.
